Francis "Frank" Gallagher is the protagonist of Shameless and the father of the six (children.
A hopeless alcoholic and troublemaker, Frank is usually shown passed out drunk on the floors around the house when he's not at the bar spending what little money the family has. Frank is careless, selfish and completely narcissistic as he hasn't done anything in his life but collect disability checks and get intoxicated. He is also abusive, conniving, being in Lip's and his own words, a "total f*cking asshole." He provides next to nothing in the way of parenting or financial support and usually serves as one of the main headaches in the Gallagher household. Frank has also shown that he would give up his own children if it meant he could get booze (or money to get booze).
Despite being easygoing, he has been shown to get very frustrated or fall into a rage at certain times. In these moments, he scares those around him and leaves them shaken. The best examples are when he attacked Ian for indirectly getting him beaten by Eddie, he threatened Fiona and V for trying to stop him from obtaining his settlement from Monica, fought Sean Pierce, when he expressed anger that shook Kev, V, and Svetlana after he remembered they were part of throwing him off a bridge, he intimidated his children into allowing him to have Liam after they kicked him out, when he attempted to burn down the homeless shelter for kicking him out and caused the homeless to flee from his actions, attack Monica, fought against Bill Darrgen, being unfazed from the threats of an armed killer that scared two of his sons who are capable fighters, and demanding that Liam’s school actually educate him.
His upbringing from his similarly abusive mother, Peggy, is most likely the cause of his manipulative, selfish, and neglectful tendencies. Frank had even wished pain on her after she continued her ways on him and putting him in his place, which is something nobody else could do. Frank heavily resented his mother, though he showed care for her as he attempted to make amends with her and was quick to prevent her from kidnapping children since she would go back to prison. He even stopped himself from nearly killing her in her sleep but did lash out at her for her verbal abuse. However, he rejoiced at his mother's death because he was freed of her. Not much is known of his status with his father, though it is suggested he resented his father too, as he told Sammi about him being beaten by his father. However, Frank did express nostalgia when telling Carl that his father took him on his first heist. He seemed surprised to learn that the man was not his father, since he realized he was the result of an affair after Liam's paternity was revealed to him. While not much is known about his status with his siblings: Jerry, Clayton, and Wyatt, Frank suggested that he extended his resentment to them and stated he alone suffered while his brothers were the favorites and supposedly got off free. Despite that, he and Clayton were once alter boys together as children but had a falling out. Even as an adult, Frank continued to harbor this disdain to his brothers: as he never told his kids about them, was angry one of them was Ian's true father from an affair with Monica, that his mother sent them money while he got none, despite him being dragged into caring for her and Clayton sending him off with nothing.
Despite the fact that Frank is quite intelligent by finishing high school and going to college, the people who know him often regard him as nothing more than a rambling drunk who provides amusement or aggravation (depending on the day). This often includes his children, who spend extraordinary amounts of time cleaning up whatever mess Frank has thrown himself into at the moment. Frank is a master manipulator, possibly because he studied psychology in college and because of his time with his controlling mother. In college, he met his future wife Monica, and dropped out of school after only one semester.
In spite of his many faults and treatment, Frank does love his children and at times proves himself a better parent than either his mother or Monica, even rivaling Fiona and Lip. This is best seen when he stayed to raise them, expressed pride in his children when describing them, felt guilt about attacking Ian, bonded with his family while getting sober and had fun with it, was upset to learn Ian wasn't his son, where he begged forgiveness from Lip and allowed him to urinate on him as his punishment after he supposedly slept with the latter's girlfriend Karen, felt guilt at losing Liam in a bet and worked to reclaim him, spoke highly of all his children when talking to his mother about them and later firmly told her to stay away from his family, bonded with Fiona over neglectful parents, felt guilt about his past neglect when Fiona brought it up in court, took the fall for Carl in a robbery and stated that's what family does, celebrated Lip's graduation with him, justified Carl's attack on bullies since he was defending his little brother, while recovering from surgery he mistook a dying little girl (whose real father abandoned her) for Fiona as a child and made promises on being a better father while being devastated the girl died, he appreciated Carl helping him with his liver problem by sharing a beer and hug with him after the surgery, and supporting his daughter Debbie throughout her pregnancy and being a teen mother. He continues to call Ian his son, despite learning that he is biologically his nephew from an affair. He also does not scorn Ian for his sexuality after discovering it and treats him like his other children. While he did not think much of his estranged oldest daughter Samantha, he bonded with her enough to confide in her about his upbringing with his parents and siblings, something that he rarely did with the other kids. He also appreciated her caring for him in his time of need and expressed pride in her knowledge of scamming people, deeming her a true Gallagher. He bonded with his grandson Chuckie after he came to accept him as part of the family, despite once not thinking highly of him and getting him imprisoned. He indirectly protected Carl from angry thugs by picking up his business after he decided to give up his gang life ways, wanted to go to his daughter Fiona's wedding because he missed many other events in her life and tried to pay for the event by blackmailing the family of his granddaughter. He was happy that his granddaughter Franny was named after him and bonded with the new addition to the family. He soon warned Fiona not to marry Sean after the latter had a relapse, even though doing so got him kicked out of the house and estranged from the family for a while. He was hurt by Carl's statement that the family (kinda) hoped he'd die after being thrown off the bridge by them. He was also hurt by their cold treatment of him in his moment of pain in the wheelchair. He named his new adopted children after his real children and spoke about them constantly, showing that he missed his family despite disowning them and their actions on him. He still got along with his youngest son Liam, allowing him to stay his child and later getting him into private school after seeing him being bullied in public school and was happy to be called a good father by him. He agreed to help Debbie out after she changed his granddaughter's name back and happily held the infant. After being abandoned by his adoptive family, he slowly made amends with his real family and fixed up the house for them and helped in other ways until he was accepted again. At Monica's funeral, he called all his children strong for how they turned out, showing he is proud of them in spite of his neglectful ways. After the funeral, he is seen very happy to be accepted by them again and forgave their transgressions on him. In the month after Monica's death, he resolved to put in the effort to change his ways and apologized to his kids for what he has done to them and while they are not properly convinced he still tried hard. However, he showed his change was genuine by threatening an armed meth head who came after the family and promised death on him if he ever came near his children again as they were surprised at his defending of them. He was seen proud of himself as he accepted Fiona's gratitude for the event. Frank continued by choosing to show real parental affection to his son Liam after realizing he was never fatherly to him and he even had fun bonding with him. He later made sure that Liam got a proper education, gave helpful advice to the oldest children, such as telling Lip to internally ready after making a change and telling Ian about religion something that caught both by surprise and to thank him. He supported the union of his son Carl and Kassidi, most likely because they resembled himself and Monica. Even after falling back into his old ways, he continues to show his love for the family such as when he empathized with Fiona over her drunken slump and told Lip to cut her some slack, since he knew the pain she was going through. He even gave his daughter advice on stopping her drinking, presumably because he realized she was turning into him. While dealing with his leg injury, he bonded with his granddaughter to pass the time by reading her a story several times. When Fiona was preparing to leave, Frank took the time to tell her of how she did a good job in helping to care for the family, nearly breaking into tears at parting with his daughter as she took his words with a smile and knew that he was just wishing her well and they parted on good terms.
Frank has a very disheveled appearance, often wearing dirty clothes. He is generally unshaven with long, greasy hair, and he often appears thin and underfed. Frank generally looks homeless (because half of the time he actually is), but is occasionally able to clean himself up when the circumstances call for it. He has several scars, some of which are from surgery or injuries.
Frank grew up as the son of Peggy Gallagher and an Unnamed Father. He had three brothers Jerry, Clayton, and Wyatt. Not much is known about his childhood, though he mentions to being abused by his parents even when he did nothing. Frank mentions that his parents favored his brothers, more than they did him but stated his father took him on his first heist as a young child and they stole plenty. As a teenager, he and his brother Clayton served as ushers together.
Frank later finished High School and went on an internship in college. He studied a semester of Psychology, using his time from his manipulative mother to advance himself. At some point, he had a relationship with a woman named Queenie Slott and she got pregnant with his child. At the time, Frank believed himself unfit to be a parent and tried to get her to have an abortion but she refused and Frank abandoned her, though they kept in touch since he knew she gave birth to a daughter named Samantha. According to Frank, he met Monica at a concert when she was being chased by a man who raped her. They fell in love and married about two weeks after dating, with Frank dropping out of college to be with her. The two soon had a family though neither were attentive to their children because of their bad habits and their series of affairs.
Twelve years before the start of the series, Frank's mother was imprisoned for running a series of meth labs and causing the death of two people in an explosion and he always hoped she die in prison. At another point, his Aunt Ginger died of an overdose at a party and he buried her body in the backyard while scamming the state that she was alive to not lose his house.
Sometime later, Monica left the family prior to the series starting, something that devastated Frank and he began to neglect the Gallagher children who came to resent him to some degree (Fiona, Lip, and Ian especially) but still love him in a way since he stayed around.
Throughout the Seasons
Frank is introduced as the deadbeat, at times absent father who is constantly drunk. The Gallagher children often find him passed out in the kitchen, the bathroom, or even the backyard.

Soon Frank bonds with his family and friends to pass the time and has fun doing so. Frank even does housework around the house by cooking and telling stories. The children are surprised that he can be a great father when he is sober, but Lip advised Fiona, Carl, and Debbie to "enjoy the moment while it lasts." It is mentioned by Lip that Frank got sober once for a bet and went to Lip’s little league game, where his son was pleased with him expressing pride in his achievements. Eventually, Frank's soberness becomes too much for the elder children when he tries to break a supporting wall with Carl.

Late on, he is able to get rid of the investigator by making him think that he injured Carl who already injured himself. At the Alibi, Frank is celebrating his victory when he is visited by Fiona, Lip, Carl, and Debbie who he tries to shoo away since he wondered where Monica was. However, they inform him that Monica was getting a paternity test for Liam and tell him he is the latter's biological father. Frank is obviously shocked to learn this, though remembers his mother's rumored affair and realizes its true. He argues with his kids before Lip punches him, out of disgust while Fiona criticizes him. At dinner, Frank argues with Monica and soon learns from Lip that he is not Ian's father, to his shock. As Frank struggles to understand Ian explains that Frank isn't his father but they are still related, since Ian is revealed to be the child of one of Frank's estranged brothers, making him Frank's nephew from a drug fueled affair of Monica. Frank is upset at both her doing drugs without him as well as cheating on him with his brother. Frank also kisses her in the argument until Bob breaks it up.
Very soon, he is upset when Monica leaves with Bob and goes on a rant.
After he allegedly had intercourse with Karen in Daddyz Girl, it is later revealed that no penetration actually occurred. Frank had to hide from an angry Eddie since he saw a recording of the event. Lip also attacked Frank for the incident until Kev stopped it. Much later, Frank was able to evade Eddie and returned to the Gallagher House where he called out for Lip and apologize for the deed. He genuinely asked him what he needs to do for his forgiveness, to which Lip responds by urinating on him from his window. At first, Frank is upset but allows this to be his punishment and lets this occur. Without saying another word, Frank laughs and walks away, with both father and son unknowingly sharing a smile.

Terry supplies Frank with a good alibi but charges him and Frank goes to get it, though is arrested.

However, Frank is released and he goes to the Jackson House where he finds that Karen told Sheila the truth about the encounter. Frank thanks Karen who also thanked Frank for supposedly killing her father.
In Can I Have a Mother, Frank is trying to do a scam for Eddie's life insurance but has to deal with the return of his overbearing and controlling mother Peggy Gallagher and gives him commands for a scheme. On the drive, he attempts to make amends with her by talking about his children and complimenting them, though Peggy is not interested. After he brings her to a surgeon named Noah Pitts that used to be her old partner, he learns that he owed her money and is worried about her plans to kidnap the man's kids. He gets involved by meeting Noah (who is familiar with him) and warns him of his mother's plot and offers him a way to avoid it and is paid seventy five grand. He meets with Peggy who says he ruined the scheme for her since she was trying to get more and stabs him in the leg for trying to swindle her. Later on, Frank's childhood habit of wetting the bed returns and he urinates in Sheila's bed, to his dismay.

That night, he secretly enters his mother's room and nearly shoots her while she is asleep but can't bring himself to do it. The next day, he argues with Sheila who orders him out of the house and he goes back home where Peggy tries to order him around. Reaching his breaking point, he angrily lashes out at her and orders her to leave him and his family alone. However, Peggy is not fazed by his outburst and puts him in his place while coldly calling him a loser who made his own life terrible. A saddened Frank sits on the porch where he is approached and comforted by Fiona who now sees why Frank is the way he is and actually empathizes with him by stating her parents are terrible too. Frank takes her gesture with a smile as they sit on the porch and share a beer. That night, as Peggy took his room, he sleeps in the old van in the backyard with Carl who wakes him up to tell him that he wet the bed. Dismayed at this, Frank tells his son to move aside for the dry area and goes back to sleep.
During A Bottle of Jean Nate, Frank later tries to get his mother back in prison but nothing works and he is forced to submit to her will.

Frank decides to visit his brother Clayton Gallagher along with an ill Monica to get money. Once there, Clayton is not pleased to see him and Frank tries to guilt him by mentioning him taking care of their ill mother before her death. After Clayton clarifies that he didn't know she was released, Frank asks his brother for some of the money to make amends. However, Clayton had already used the money to pay his mortgage and orders him out. Clayton also resists Monica's advances and watches as they leave.
Frank loses the support of his daughter Debbie after he ruins her project, this causes her to physically attack him with a bag of soap until he loses consciousness and he is thrown away by Lip and Ian.
Frank later calls Child Services at the Alibi in an attempt to get back into the Gallagher house, as he has been kicked out by Fiona. In the episode "The Sins of My Caretaker" an Asian woman is hesitating to go into the Gallagher house. A bloody Mickey is seen being carried into the house from getting shot at a failed robbery attempt. Fiona walks in when she hears Mickey screaming in agony as Dr. Lishman is removing a bullet from his buttocks in the kitchen. The daycare is out of order and Debbie, wearing a bathing suit walks in excited about her growing up moment at the pool. Fiona is surprised to see an unknown woman in the house and asks who she is. The Asian woman replies that she is with CPS. Much to Fiona's surprise and dismay, she later finds out that Frank had called child services. When she searches for the rest of the Gallaghers to see what homes they were placed in, she eventually convinces Frank to participate in a parenting class. In exchange, Frank asks for a free room back at the house and Fiona agrees. She at first looks for Monica. She calls her grandmother, Monica's mother, who apparently didn't remember her own daughter, but failed to find her and resorted to Sheila with the help of Frank. Sheila was again bothered that Frank showed up again to her house but agreed. Fiona asked the social worker who contacted CPS on her family to which the worker reluctantly allowed her to listen in secret due to violation rules. Fiona hears the tape and recognizes Frank's voice.
Afterwards, Fiona moves to file suit and convince the courts to terminate Frank's parental rights. A custody fight in court gave Fiona the position of legal guardianship of the Gallagher children but Frank still has rights as a parent. As a result, Frank has been kicked out of his home and finds himself sleeping on the subway and fighting with homeless men.
Eventually in Order Room Service, he runs into Carl, who sneaks him in the van in the backyard. After a moment with Carl that night, Frank and Carl come up with a plan to steal from Carl's previous foster parents once he tells him his father took him on a theft. That night, he and Carl celebrate their acts but when Carl leaves, he is caught by the cops. Frank overhears Lip trying to defend his brother before he appears on the scene. Frank tells Lip that he's come home and the officers tell him they are bringing Carl in for questioning. In a rare moment of fatherly compassion, Frank takes the fall for his son by claiming it was him who stole, proving it by revealing some of the stolen items and stating he forced Carl to give him the code. After turning Carl over to Lip, Frank tells the officers to arrest him before he gets disorderly. As a result, Frank is charged with theft and arrested by the police and tells his children to hang on as he is taken away with a surprised Lip, Carl, and Ian watching in surprise at his actions.
During Survival of the Fittest, while in jail Frank's alcoholism begins to catch up with him as he can barely stand as his body and health begins to deteriorate. He is released from custody on technicality, he tries to spend time with Lip when he runs into him at The Alibi Room and tells him that he took the blame for Carl since he was family. He then hears Lip graduated school and congratulates him, where the two challenge each other on doing push-ups. Afterwards, Frank decides to continue the bond by having Lip join him for a steak dinner, in Lip calls him Dad. Frank is further proud of him when he suggests they dine and ditch before they go skate at the park. It was there when Frank is rushed to the hospital after falling down unconscious and vomiting blood. Fiona visits him in the hospital denying Carl and Debbie access. After she tells Lip to go home, she sits down and talks with Frank. Fiona tells Frank that she would have preferred that he died since the thing she fears the most about Frank is him not caring for his own kids. Fiona then informs Frank how much her and the rest of the kids love him and want him to change. Carl visits Frank at the hospital and shaves his head, as it's presumed Frank may have cancer. Eventually Frank decides to get out of bed and walks out of the hospital and on to the streets. He walks alone alongside an empty bridge as the winter snow begins to fall.
As seen in Simple Pleasures Frank's liver fails, leaving him to make a life-changing decision to either find a donor or live out his last days. Frank's health is declining and he's becoming too ill to take care of himself. It's revealed that Fiona has allowed Frank back to live in the Gallagher house.
In My Oldest Daughter Frank is tended to by Carl who supplies him with prescription drugs to ease his pain. He is also proud of the latter's activities of trying to help him and his suggestions of painkillers for him. Afterwards, Carl begs Fiona to donate her liver since they are a match but she refused to be a donor for him, since it was his own fault. Frank watches his depressed son leave but tells Carl that if Fiona won't help, he'll go to his other daughter for help. When Fiona states Debbie is too young for surgery, Frank tells her that he was talking about his oldest daughter Samantha, which greatly surprises Fiona. Frank leaves while glaring at Fiona for her refusal to help him.
During Like Father, Like Daughter, Frank and Carl locate Samantha now a grown adult with a successful career and a kid of her own Chuckie, making Frank a grandfather. Frank arranges a scheme to look good in front of his daughter and it works with him meeting Samantha. Unaware that he's her father upon meeting him, she is sexually attracted to him, to his discomfort though he plays along.
In Strangers on a Train, Frank accidentally reveals the truth when she informs him that she cannot give him her liver, as she is not a match. Although intensely enraged at her unintentional supposed moral crime, she tracks him down and quickly accepts him back, reconciling and bonding.
As of There's the Rub, Frank continues to bond with Sammi and Chuckie since they are aware of their relation. Frank introduces them to one of his other children Carl, much to Sammi's delight. Frank tasks his son to build a sweat lodge, after Sheila's boyfriend gave him advice on this potentially helping his liver.
Very soon in Iron City, an ill Frank is taken care of by Sammi. Frank takes the time to explain that his estrangement from her stems from his youthful immaturity when he became a father, with his initial desire to abort her, and his uncertainty about how he impregnated her mother. While Sammi is hurt at first, she lets it go after he calls her a miracle for how she turned out and has him look into hospices for help but he refuses to stay and she takes him home. Due to Frank having parental rights, he is needed by the Gallagher children to get Liam discharged from the hospital. Lip searches for him but is unable to find him though Carl locates him at the house and tells his brother. The next day, Frank introduces Samantha and Chuckie to his other children (except Fiona and Ian) and they are surprised by the new addition. Also, they are able to reclaim Liam with his presence at the hospital.
As of A Jailbird, Invalid, Martyr, Cutter, Retard, And Parasitic Twin, Frank has returned home with Sammi being allowed stay to tend to Frank when her siblings give her a chance though warn her of Frank's real personality. Sammi forbids the protesting Frank from any drugs since it could put custody of Liam or any other Gallagher child at risk, to which he begrudgingly agrees. While resting Frank takes the time to let Sammi learn more about their family, telling her his upbringing with his siblings, his life with abusive parents and how he alone suffered. Soon Frank persuades Sammi to give him drugs after calling her like the rest of his kids and she relents. Hours later, he was found unconscious on the bathroom floor by his kids. Seeing this, Lip kicks Frank out along with Sammi and Chuckie. They move into the house of Sheila, since she left for a while.
They are later visited by the other Gallagher children Carl and Debbie in Hope Springs Paternal, with Carl helping Sammi in tending to Frank. Later on, Frank has to appear at Carl's school conference for his attack on bullies who made fun of Liam. Frank is taken there by Sammi and defends his son's actions, as he was defending his brother and he may have helped better the victim's lives and uses examples of those bullied that gained success. His act caused the school to drop the trouble against Carl.

He is later visited by Carl, who tells him of Sammi and Sheila are arguing with security to see him before he is wheeled out by Carl while they see the argument. Carl takes Frank along the Chicago waterfront where Frank takes out a can of beer and victoriously rejoices about surviving and still being able to drink.

In Tell Me You F**king Need Me, he comes back to his house where he ignores Sammi's threats to leave. Frank tells Sammi that he doesn't have to leave his house, as she aims a gun at him but Frank challenges her to shoot. She appears to not go through with it but shoots, grazing Frank's arm. The other Gallaghers watch while Frank is on the ground with Sammi pouring salt on his wound and demands Frank state he needs her. Frank complies and the gleeful Sammi once more calls him "Dad". Frank is taken to a hospital by her and gets an arm cast.
He pretends to make nice with her but secretly plots to get even with her act.
Frank bumps into Bianca, a doctor who has been diagnosed with Stage 3 Pancreatic Cancer. He encourages her to try many drugs for the first time and because she has decided to avoid treatment, she does many life-threatening stunts. The pair goes overseas where Bianca disappears.
Frank starts off the season by trying hopelessly to find the reason why his beloved Bianca was taken from him. He spends time making visits to every religion and trying them out, hoping to gain peace of mind. After Bianca's co-worker tells Frank she stayed with him because she was at life's end, Frank runs similar scams trying to get more money.
Eventually Frank supports Debbie through her pregnancy, with her calling him "Dad" again. He also supports the recently released from juvie Carl in his thug life by asking for money. After the Gallagher house is sold, he tries to find Debbie (and selfishly himself) a place to live and a means to make money for her pregnancy by setting her up as a nanny in a household with a dying mother. The pair leaves when the mother is in remission.
Frank later returns to the abandoned Gallagher Household where he finds his grandson Chuckie camping under the porch, he sees that the latter was not told of the family being thrown out and has been there for two days. Feeling sympathy for him, Frank stays with him for the night and they bond over food and he starts to accept Chuckie as family. When Queenie (Sammi's mother and Frank's ex) returns to Frank's life to claim Chuckie, he is happy to reconnect with her even more so after the house is brought back. Frank then tries tirelessly to prevent her from leaving him again. He is later proud of Chuckie's outspoken (though misguided) views and speech.
After Carl decides to quit the thug life, he goes to Frank for help and the latter decides to pickup where Carl left off. He does well at first but soon he and his temporary accomplice waste through half of the drugs he was assigned to deliver and he is chased violently by G-Dogg's crew. Frank takes refuge with Debbie at Queenie's commune in the woods. Debbie hates it and nearly gives birth in a hospital, naming her daughter after Frank who was taken by G-Dogg's men. Frank narrowly escapes death by telling them of the opium at the hippie camp, he is lucky when the hippies attack the gangsters and presumably kill them while he narrowly escapes, abandoning Queenie and Chuckie. He returns home and learns his granddaughter Frances Gallagher was born and was named after him. Through less-than-honorary means, Frank blackmails of his granddaughter Franny's relatives and raises money to help pay for Fiona's upcoming wedding. After getting into a fight with Sean, Frank attempts to place a hit on him and fails, so he proceeds to purchase a gun.
Before Fiona and Sean's wedding, Frank arrives and is greeted with disdain. He demands to give Fiona away at the wedding, a manipulation so he can tell his entire family their wrongdoings - including Debbie - and reveal he broke into Sean's office and found heroin. This is the last straw for the Gallagher children, as Lip punches him until he is stopped.
Much later, Kev, Veronica, Svetlana, Caleb, Ian, Carl, and Debbie kidnap Frank and throw him off of a bridge into the freezing river. They leave the area while happy to supposedly be free of him.
A month later in Hiraeth, Frank has survived the event once he was found and pulled out of the river being only in a coma before he wakes up in the hospital with mild amnesia and leaves the hospital after receiving a heavy bill as well as learning nobody looked for him. He receives a wheelchair and returns to the Alibi for a drink while Kev, Veronica, and Svetlana are shocked to see that he has survived the fall and he explains his condition. He talks with Kermit and Tommy about his injuries being temporary as he calls Kev and the others out on not looking for him.
He is confused by their reactions after they state he doesn't remember what happened after the wedding and how he ended up in the river. Looking upon their worried expressions, Frank soon recalls the event after the wedding and that they along with his children were the reason he was thrown off a bridge. Frank is angry at this and curses them for what they did to him before leaving, with the three being left scared at what he might do now. Kev was the only person who actually felt guilt about throwing him away after seeing his condition. He tries to move back in his house by getting Liam to let him in. Frank passes out while eating, he is found by his other sons who aren't too surprised to see that he is alive. Frank later learns from Carl that nobody tried to find him, since they kinda hoped he'd be dead, depressing him. This is further seen when the family treat him with disdain and displeasure at his return. Very soon, Fiona forces him out for his wrongdoing at her wedding, though it was later revealed Fiona appreciates his act of ruining the wedding, since he did her a favor. He is angry and later sneaks back in after nailing the door to his room shut, though Fiona again kicks him out.
After recovering and being back on his feet in Swipe, Fuck, Leave, Frank sees that The Gallagher children no longer want anything to do with him. However, Kev states his relief to see him on his feet again, while Frank glares at him. Believing that his family was the one who ruined his relationship with them, Frank disowns his children who are more than pleased by this and kick him out as Debbie begins using her daughter's middle name to distance her child from Frank. However, Frank promises to get even with his family for trying to kill him and insulting him since his return. He carries out his agenda by taking his only loyal child Liam for a while and ignores the older kids' protests at this. Using a stolen credit card from Debbie, Frank hires contractors (who he promises to pay fully) to block the other children out the rooms of their house with walls of cement and force them into cramped spaces, something they already realize was because of him and are angry at his revenge. He also gains a new girlfriend after having Liam charm her and celebrates his victory over his children by drinking the night away in his old room. His children try to get rid of him but he maintains his stance and continues to get payback on the family by throwing a raccoon to harass them, while insulting them for their treatment of him. Soon he and his girlfriend are forced out when the kids demolish the walls.
In Home Sweet Homeless Shelter, Frank moves into a homeless shelter and has several teens assume his family's names, including renaming his current adult girlfriend Delores to Monica. When he learns the shelter is closing, he has his new family search for a new home and they end up crashing a home realtor's showing on his old block. Getting an idea, Frank returns to the homeless shelter and has the dozen homeless people there join his Gallagher 2.0 family. Frank tells the realtor who was familiar with him that the old owner gave him rights to the house but she isn't buying it and calls the police for his trespassing. However, Frank manipulates the police officers who show up into having them think the homeowner okayed the trespass. The police were also well aware of who he was and considered him to be lying but they did not have it in them to throw so many people on the streets. Frank celebrates this victory before he and his new family go scavenging with Frank encountering Carl along the way and shares a tense glare with his son. That night, he finds a nun and asks her church to supply food. The next day, he throws a party at his new home before his real children and friends show up to protest his choice. Now having the upper-hand against them, Frank tells his former family (except Liam) to leave him alone since they have shown him their real feelings with their acts on him and sends them off while he continues to bask in his fortune.
As of I Am a Storm, his shelter starts to earn controversy by the neighborhood so Frank decides to make money from donations. He is introduced to Ian's new friend Trevor who works with homeless and likes him for his efforts. Frank is somewhat annoyed with Ian though he is thankful for Trevor's words. Despite disowning them, Frank continues to talk about his old family who still claim Frank as their father. Later on, he chains himself to the railings of the house on a televised interview in the rain, receiving both compliments and disdain from the people who know him.
Very soon in Own Your Shit, Frank is told of how his recent act has caused him so much support that he technically own the property. He is happy with this as he bonds with his make-shift family since they have made the shelter stronger. Frank is basking in his victory, as he is visited by his daughter Debbie and granddaughter. She tries to make peace with him long enough for him to help teach her in the art of scamming. Frank (still holding a grudge against her) refuses to help a "Gallagher traitor" and she makes him consider his granddaughter and he brings up on how she changed her name to distance her from him. Debbie offers to change her name back if he does help. Hearing this, he agrees and happily holds Franny before telling his daughter to go begging, since she fits the part and people will love to help her. Afterward, Frank and his family take a picture with the house's new owner and Frank has him send furniture and necessities for the house. He continues to treat his new family well by getting them things, though starts to horde money from the shelter to treat himself.
During The Defenestration of Frank, he is still hording money but does treat his adopted family. Later on, while counting his money, he is visited by his daughter Debbie. She tries to make peace with him long enough to give his consent for her marriage to Neil Morton. Frank refuses and tells her marriage is important but this causes an argument that reveals his money hording to his new family. That night, he goes to his old house where Carl is displeased to see Frank returning. Carl insults his father but is angry when Frank tells him about the new items in his shelter and takes Liam to enjoy those things while insulting Carl. However, when they get back, Frank's new family reveal the money and proceed to kick him out by throwing him out a window, breaking Frank's arm and injuring his leg in the process. Abandoned by both his families, Frank is forced to sleep on a park bench for the night after being treated for his injuries.
In You'll Never Ever Get a Chicken in Your Whole Entire Life, he goes back to the house where he angrily rants about all of the residents being "ungrateful", as he tries to burn the house down in retaliation while his former adopted family secretly run out in fear of his actions. As he tries to light a match, Liam comes to him for advice and Frank talks with him. With Liam, Frank takes him to school only to find it closed for the day and the two go to Frank's old private school but are told to leave. When dropping him off to another school the next day, Frank sees Liam get bullied by his peers, to his frustration. In a rare moment of fatherly affection, Frank ends up getting his son enrolled in private school with a paid tuition after harassing the school enough to give his son a chance. As thanks, Liam calls Frank a good father and hugs him as he goes off with a proud Frank watching him.
As of You Sold Me the Laundromat, Remember?, Frank has recovered from his injuries and returns to his old home after stealing back some of his old possessions from the shelter (as revenge) to improve the Gallagher House. Despite this, he is still kept out by Ian who doesn't trust him while Ian's boyfriend Trevor criticizes him for his acts on the homeless. However, Ian allows Frank to walk Liam to school but threatens him if he takes Liam begging. Much later, he was chased off by a mob of the homeless for the theft but escapes them. By this point, he is now at a low state and doesn't have much to protest about, as seen when he doesn't argue with Svetlana about paying for drinks at the Alibi and his friends are surprised by this. He has started to try in making amends with his children by helping Fiona in remodeling her Laundromat, caring for Fiona's senile tenant, allowed to take Liam to school by Ian, and the rest of the children with other matters.
When Monica returns in Ouroboros, she attempts to reconcile with Frank who casts her aside until deciding to speak with her and learns she is dying from an brain aneurysm that she may have gotten from an infected needle.
They resort to their old habits in Ride or Die once again for the next few days and are able to go their old home since Ian had left to be with Mickey.
Afterwards they decide to renew their vows in Happily Ever After, they celebrate and have their kids join in. When morning comes, Frank tries to wake Monica up but realizes that she has died and he breaks down at his loss.
During Requiem For a Slut, the family go to the hospital with Monica. Fiona notices Frank was not present and Debbie tells her that he is outside on the curb. Devastated at losing his true love, Frank sits quietly while ignoring Fiona's attempt to comfort him and leaves to drown his sorrows in a bar. Soon he returns home, where he passes out on the floor. He is found by Fiona, who feeling sympathy for him gives him a towel to rest his head. learns that Monica left 70 pounds of meth for the children with Carl, Debbie, and Liam locates it. Frank later fights Monica's father Bill Darrgen who arrives at the Gallagher Household and blames Frank for supposedly ruining his daughter. Bill also paid for the funeral services and Frank watches as his children speak for her. Before anyone leaves, Frank has some heartfelt words about her and tells his children that their mother loved them and they are all strong and wouldn't be who they are without her before he leaves.
Afterwards, he finally returns home with all animosity with the family ended and him once more accepted. He celebrates his return by dancing with Fiona who allows him to lead. Frank and Carl later go to an alley, where Carl graffiti's a wall in honor of Monica. Frank is shown to be proud of the gesture, as he and his son share a beer to pay their respects together before leaving.
In We Become What We... Frank!, he meditates after smoking Monica's methamphetamine and is seen with only a mustache. Frank says that his time away has changed him for the better because it helped him move on after losing Monica. Monica's death truly devastated Frank, but he determines his life is so horrible because of her manipulation over the past 30 years. From this epiphany, Frank decides to turn a new leaf and become a responsible adult. By doing this, his children begin to believe he has lost his mind since he has taken to apologizing for some of the wrong he has done to them. He also apologizes to his old friends who are more less confused by his change in attitude but let him try to make it up.
As of Where's My Meth?, Frank gets a job at a hardware store by telling the manager his story and sympathizing with the latter over failed marriages with controlling women. He quickly climbs the ladder to management with his new upbeat and 'by the book' work ethic.
In God Bless Her Rotting Soul, he is told of how Carl and Ian were spotted by the meth head and his children ask what his plan is since he got them into the ordeal. Frank tells them that this was his old self but tells them to relax as they needed to keep their heads down and maintain their story of ignorance. He later asks to be referred to as 'Francis,' and discards 'Frank' as the name associates with his treacherous past. While continuing his work at the store, he becomes supervisor as Fiona comes there and he requests to be called Francis or Dad. Fiona ignores this and goes about getting tools since he denied her a family discount. When his children face problems with Monica's old partner Eric Stark, he refuses to rob his job for money though experiences guilt. He and Liam go to Fiona's apartment building, where he tells the rest of his kids that he has decided to help them. Fiona has him help with digging Monica up after he gets them tools from his job. After getting the meth, they go to the storage unit and pay Eric but its still not enough and Eric threatens the kids at gunpoint. Seeing this, Frank steps in and defends them by telling the angry meth head everything that he and his children went through with Monica along with her death. Staring Eric down, Frank tells him to accept their payment before he successfully intimidated the man by promising death on him if he ever came near his family again. His children were surprised at his actions and saw his new change was genuine as he leads them to safety. Because of his defending them, Frank earns gratitude from Fiona who calls him Francis as he requested. Frank is happy with this recognition and they go home.
During Fuck Paying It Forward, Frank has decided to act like being in his thirties and overhears from his sons that Sean Pierce returned. He tells them he has decided to forgive the man and act more fatherly shown by giving his elder kids useful advice as seen with telling Lip about readying for change and the latter is thankful for the help. Ian then remarked that Frank is out of kids to ruin with his new ways, but Frank states he still has his youngest son Liam and will raise him properly since Liam is his last chance. With that, he takes him to his school as his other sons look on. Walking his son to school, Frank asks him for tips about being a good father but the latter doesn't know. At the advice of a mother, Frank joins the PTA and decides to show what real labor is for the children. He has Liam join him and this ends up being fun for both of them as the two bond at a car wash. He even bonds with his granddaughter Franny who walks to him. While he continues to show change, his children are still skeptical but let him go on to humor him, since he's doing better as "Father Frank" or "Saint Francis".
Through his new behavior in The (Mis)Education of Liam Fergus Beircheart Gallagher, he has been rewarded with beautiful women of Liam's school who are aroused by his rugged appearance. He ages himself to his forties and opens a bank account and buys a new car for his commute, which he and Liam go riding in. Frank also makes sure Liam gets his education after seeing falling behind in school because of them using him as a token child, which allows him to excel. Because of this display, the older Gallagher children are surprised to see how fatherly Frank can be.
Frank continued to do good only to be fired from his job shortly after, due to downsizing. He attempts to do the honorable thing and find other work but only discovers minimum wage work willing to hire him. While drowning his sorrows at the Alibi, he meets several foreigners from the Middle East wishing to be smuggled into Canada. Frank starts a lucrative venture by helping smuggle them across the Northern border. While in Canada, Frank also buys cheap medicine and flips it at home for profit. This business quickly goes under when the Canadian Mounted Police discover his hiking trail and capture him. Frank barely escapes and gets home, but also barely escapes the angry mob that lost their investment in Frank's medicine smuggling ventures.
Frank reverts to his old self at this point, and only seems to care about his own interests again but still spending time with the kids. He later decides to retire and discovers his benefits would be next to nothing because he never held long-term work. In an attempt to earn his own retirement, Frank creates t-shirts to sell at Ian Gallagher's church rallies labeled "Gay Jesus," and pockets almost all the cash for himself.
Frank continue to spend most of his time with Liam who helps Frank with his schemes, but also offers an inside track for Frank to sample the upper class because Liam's friends all have wealthy families. Most of the wealthy families are first-generation wealth, and the parents have a peculiar relationship with Frank. The housewives collectively find Frank attractive because he is everything their white collar husbands are not, which some find irresistible.
In Are You There Shim? It's me, Ian, he continues to revert to his old self and continues his affairs with the rich women while stealing from them. He tells a maid (in Spanish) that he is not bothered by threats. He soon has Liam hold the loot while he keeps up his acts. It was shown at a PTA meeting, he has spread a series of STD's to most of the mothers at the school who spread it to their unfaithful husbands. Frank is named the source after it is revealed that he slept with all of them. He and the parents all get their STD's tended too and he is surprised when some of them become thrupples, while he is punched by angry man as the wife promises to call him.
During Mo White!, he picks up signs for congress candidates and profits from the campaign managers. Frank overhears Lip and Ian's talk while commenting to his son that the reason his Shim, an-invented word for the genderless God, isn't talking is because he was hallucinating. Frank talks to Ian about religion and talks about the basics of it and has him figure it out, as Ian considers it. Eventually, he makes a scam where he decides to nominate Mo White for congress.
In Weirdo Gallagher Vortex, Frank and Mo go out to gather supporters with things going good. At home, he tries to get his kids to support Mo while also telling Ian that prison wasn't bad from his experience. Later on, Frank is shocked to discover Mo is a sex offender but the latter asks him for his support.
With the election drawing to a close in Do Right, Vote White, Mo is in dead last and decides to call it quits, seeing no reason to continue, much to Frank's dismay. Knowing that the political runoff would be enormous if Mo were to win, he pays a visit to the released Terry Milkovich who asks for his help on election day to ensure that Mo White is victorious by having his neo-Nazi and white supremacists colleagues and surrounds the polling place to non-violently intimidate any minority from entering the building while only letting the whites inside. However, a violent riot ends up breaking out between the white supremacists and members of the Church of Gay Jesus.
Frank later meets up with Mo in Black Haired Ginger, where he admits that while it may not have gone smoothly like he hoped he was still proud of his efforts. They hear people cheering at the results of the election on television. They walk over to see the results and are shocked to learn that Mo White is the surprise victor with just over 52% of the votes. Mo's victory comes to a complete shock to South Side's residents with pollsters believing that his victory was in large part due to the vast number of Caucasian voters and their reluctance to admit to that they voted purely out of bigotry. Frank asks Mo what he plans on doing now that he's back in Congress, and pridefully responds "Absolutely nothing." He states that the beauty of being in Congress is that he doesn't have to do anything for anyone but himself.
During his first televised speech, Mo is seen with an underage girl and this surprises as well as disgust Frank to see he hasn't learned his lesson.
In Face It, You're Gorgeous, Frank has been dismissed from his duty by Mo and falls into a drunk stupor, found passed out at the Alibi by Veronica. He shows an illness after his urine is black, he is rushed to the hospital by Kev and Veronica. Frank is told this is because of his new liver acting up. He doesn't listen and falls into his habits again and heads back to hospital, who give him medicine that calms his liver but he gets erectile dysfunction and can't perform well. Frank goes to the hospital and meets Ingrid Jones, a manic woman who jumps him and sexually assaults him before running off from the room. Frank was confused but happy he had his charisma back and decides to pursue her. With Liam's help, he goes in search of Ingrid and finds her at a hospital, getting her medicine.
Soon in Down Like the Titanic, he and Ingrid form a relationship but where next door neighbor and ex-husband gets in the way. Frank manipulates him into taking a trip as a way of coaxing him out of worrying for her.
In The Apple Doesn't Fall Far From The Alibi, Frank is shown passed out as Fiona finds him and takes his drinks. Frank and Ingrid go out with her taking him to a clinic. She reveals that she wanted him to fertilize her stored eggs so she could have children. Frank agrees wholeheartedly at the chance of being a father again. However, he learns that because of his habits and medications that his sperm count is low, with the chances being severely low for him to reproduce. Frank takes a sample cup home for him to deposit in but plans to have one of his sons do it. With Lip out, Frank goes to Carl and bribes him with the hundred dollars Ingrid gave him. Carl fills the cup all the way, unaware of what Frank intends to do with it.
During BOOOOOOOOOOOONE!, Frank and Ingrid are at the lab and the doctor reveals their possibility of having a child are now up. However, Frank learns because of Carl's sperm, he and Ingrid are expecting septuplets and when the doctor reveals the risks of carrying the children to full term, he readily agrees to abort some of the kids. Ingrid is less than upcoming with this, but he seemingly convinces her. At the Alibi, he reveals the good news but is worried when Ingrid refuses to abort three of her kids and make him get a job to support them. Frank and Ingrid reveal this to the Gallagher children, who are shocked by this but doubt he could support more kids since he didn't do it with them.
During Los Diablos, Frank applies for the hobo loco and tells a fellow contestant he should win. Frank furthers his reasons as he mentions his depressing life by burying Monica, his cancer riddled girlfriend Bianca, and his unloving mother Peggy.
In The Hobo Games, he competes with Mikey throughout the games. At the end, he loses and Ingrid leaves him while telling him that she will reduce the embryos. Her ex-husband also pays Frank off and he allows this,
In You'll Know Bottom When You Hit It, Frank is at home before he learns of a blackout and takes the time to meet an old friend for help in scamming people for help in exchange for sharing profits. Frank also bonds with Fiona over being kicked out when Lip fulfilled his promise. Frank offers her a deal in his scam, she reluctantly decides to work with him in surviving the blackout for half of the profit. Father and daughter's plan was successful even though Frank told her to stop drinking because of her uncontrollable nature. During a party, he is so happy that he gives Kev free ice for his recovery of his vasectomy as a show of good will. At the end, he is passed out next to Fiona in her old apartment building and Fiona realized she was nearly like him, which caused her to revaluate her standing.
During Lost, Frank is left in the building by Fiona and is woken up from the demolition taking place. He narrowly runs out and is insulted by the crew for trespassing though they offer to tend to him after he injures himself but casts it off. He makes it home and passes out by the fence where he is spotted by Tami's father who mistakes him for a homeless guy. Frank wakes up as Carl spots him and hears his groaning. Carl nearly leaves his injured father but helps him when Frank begs him, along with Kelly and Debbie who finds his bone sticking out. Frank rests on the couch while refusing the hospital, as Tami's father questions this before Frank's kids find pills on him and deduce he didn't want ambulance because of it. After the people Frank called take the pills, an ambulance arrives, the paramedics are familiar with him and take him to the hospital with Fiona being by his side until he receives help. He is given surgery by a new but professional doctor and after given a prescription, the hospital staff have him sent home. He is loaded in a wheelchair and let out in front of his home.
As of Found, he is now sleeping on the couch and taken care of by the family. He tells Fiona his recovery will take months but he wants his meds though is refused as Debbie hid them and the children are fed up with his whining and needs. When the family leave, Frank is upset before his granddaughter Franny keeps him company and he uses the time to read her story but does so several times. Soon, Debbie hires a caretaker named Seamus, who Frank was familiar with to do most of the grunt work. When Fiona was preparing to leave, Frank noticed that she was skipping the party Lip was going to throw her. Frank sends his caretaker away and took the time to express his gratitude to his daughter for caring for the family, as she took it in stride and he told her to accept it if it helps her sleep. Fiona noticed that he nearly burst into tears and smiled at him as she realized that this was his way of wishing her well and said goodbye to her father. During the party, Frank mostly drank beer as he sat on the couch while his granddaughter approached him.
