Ian Clayton Gallagher was born in 1996 in Metz, and is often the most strong-hearted, persistent, and goofy -yet currently reckless- third oldest child in the Gallagher family. He is presumably the product of a PCP-fueled affair between his mother Monica Gallagher and Frank Gallagher's brother, Clayton Gallagher, in the summer of 1995. Ian has been diagnosed with Bipolar Disorder; he currently refuses to visit the doctor and does not believe he needs to take medication. For these reasons his behavior has been erratic and out of control, worrying his family. He is a high school drop out, having left his education behind when he illegally enlisted in the army at the end of Season 3. While in the army, Ian attempted to steal a helicopter, and was a wanted criminal on at least two charges: attempted theft of government property and impersonating his older brother, Phillip Gallagher. He has been in an on-again-off-again relationship with the aggressive neighborhood thug, Mickey Milkovich, and was best friends with Mickey's sister, Mandy Milkovich; he has complete hatred for Mandy's abusive boyfriend, Kenyatta, with whom she moved away to Indiana in Season 5. He helped around the house and assisted Mickey and Svetlana with the care of their son Yevgeny.
After spiraling out of control, Ian becomes a religious fanatic in Season 8 and is arrested. During Season 9, Ian is sent to prison to serve a two-year sentence, where he is reunited with Mickey Milkovich and his character was temporarily retired from the series, making an appearance in the season finale before Fiona leaves. Ian returns in Season 10 with Mickey and both are eventually paroled. Ian struggles with life after prison, building a future with Mickey and his own insecurities, but eventually he and Mickey get engaged and are eventually married.

- 6 Notes
Ian is not as intelligent as Lip, but he is more physically fit. He is described by Frank to having an excellent work ethic in nearly everything he does. He is often uncertain of what he wants to do in his life, but once he makes a goal for himself he goes after it 100 percent.
Ian is also self-conscious of his bipolar condition, which he inherited from his mother and often feels inadequate as it prevents him from certain things. He sometimes refuses to admit that he has a problem when his condition causes him to go off his usual path.
Ian gets along with all his siblings who were aware of his sexuality long before he revealed it and accepted regardless. He is closest to Lip and Fiona but does get along with his younger siblings and often help shield them from Frank's influence. Ian was devastated by the betrayal of Samantha Slott who told the army of his AWOL choices. However, he did try to redirect Samantha's son Chuckie Slott from his misguided views from juvie.
Ian like his siblings resents his father Frank for his neglect and his treatment of him since his mother Monica left them. For some time, Ian felt his father despised him the most. However, he was greatly surprised to learn Frank wasn't his biological father but rather his uncle. After meeting his presumed father (Frank's brother), Ian chose not to broach the subject and accepted Frank was his father, just as Lip and the others are his siblings. Interestingly enough, Frank also claims Ian is still his son while not scorning his sexuality and accepting him no matter what. Despite stating he hates him, Ian was worried when Mickey plotted to kill Frank for discovering he was gay. Ian also warned Frank of the danger he was in but listened to his father's words about his life. Ian was even present for Frank's time in the hospital when it looked he was going to die from liver failure and even seemed sad. However, he went back to his usual reaction to Frank after he got a new liver and survived. After Frank ruined Fiona's wedding, Ian took part in throwing Frank off the bridge, he wasn't surprised to see him alive when he returned and didn't try to help him in his moment of pain. Ian also expressed pleasure in Frank's disownment until Frank took revenge by taking Liam and blocking the family out of the house. This tension skyrocketed to the point where he and Lip were tortured by Frank with a raccoon and Frank created a new family while sending him away. Ian's anger mellowed when he introduced Trevor to Frank and still called Frank his father. However, his dislike remained as he tried to attack his father after he tried to return home but soon relented and slowly forgave his father when he helped Liam and fix the house. Ian made full amends with Frank after seeing his grief at Monica's death and hearing him express pride in them, despite their past. In the month after, Ian was also surprised to see Frank put in the effort to change and saved him along with the rest of the family from an armed meth-head while realizing Frank was holding back on him for years in his attacks on him. Though not entirely convinced but grateful for the rescue, Ian seemed to encourage Frank's actions and was pleased that he put in the effort to bond with Liam. Regardless, Ian does show that he cares for Frank and was pleased to see him happy when he turned his and Mickey’s wedding.
Ian is gay and has had several troubled relationships over the course of the series. He had several flings with Kash and Lloyd but neither of them worked out because of their complicated lives getting too much for him, resulting in Ian dumping them. His first relationship was the neighborhood thug Mickey, who was the person that he wanted to be with all the time but he was devastated Mickey's pride and reaction to his bipolar disorder blocked that. His second relationship was with firefighter Caleb who was different from all his partners in that they were doing normal things, as they went on dates and confided in personal secrets: Ian being bipolar and Caleb being HIV positive. Caleb was also more encouraging, as he pushed Ian to fight to be a paramedic, something that was a success. Their relationship lasted a month, as Ian discovers Caleb was bisexual and cheating on him with women. Ian's next partner was Trevor, who is transgender and showed a mutual attraction to him. Though Ian just broke up with Caleb, he felt different with Trevor and after moving past differences, they slowly built a relationship once they found common interests. Ian ruined his chances by cheating on Trevor when hooking up with Mickey and nearly running off with him. However, Ian returned to Trevor and they started to reconcile until Ian became a religious fanatic and arsonist. In prison, Ian reunited with Mickey and they resumed their status. Ian and Mickey had reconciled in the six months that passed but things became tumultuous due to the fact that they would constantly fight about small things. Regardless, they still cared for one another as Mickey prevent Ian from ruining his parole meeting and helped Ian in getting a phone for him to see his new nephew Freddie Gallagher. After they were both released from prison they moved in together and things were more smoothly than in prison. However, Ian hesitates at the idea of marrying Mickey, eventually revealing that a lot of it stems from insecurities over how Mickey could love Ian with all of his issues when Mickey could potentially find someone better. After overhearing Byron bad-mouthing Mickey and his qualities, Ian is inspired to not only leap to Mickey's defense, but to propose to Mickey himself. Despite the turbulence at their wedding plans and the reactions of Mickey’s father, Ian was ultimately able to marry Mickey with the help of his family, friends and even his old Gay Jesus followers. With Mickey as his new husband, Ian couldn’t help but be happy about finally finding the person he truly wanted. The only sadness Ian showed was that Monica couldn't be there to witness the wedding.

The following morning Ian is attacked in the kitchen by Terry Milkovich, father of Ian's beard Mandy, because he believes Ian has gotten her pregnant.
Ian spends the next few days avoiding Terry, but it becomes increasingly more difficult. Lip suggests they plant Grammy's old gun in the Milkovich home; this will violate Terry's parole and, if the gun is tied to a murder, could get him incarcerated for life.

Ian asks Mandy for some advice about knowing if a guy is attracted to you. Mandy says that he would know it when he looks in his eyes. The next day Ian saves a kid from Mickey's wrath. Ian then tries to stare at Mickey's eyes, seeing if there was the supposed "look", but Mickey only asks, "The fuck are you lookin' at?" Though later he realizes that Mickey must care about him when he follows him and Lloyd on a date.
Mickey starts becoming jealous because Ian is seeing the other men. Eventually, Lloyd reveals that he is pansexual when he is kicked out of his house and calls Jimmy soon after. When Lloyd and Jimmy come back to the Gallagher house after drinking at The Alibi Room, the older man seems to want to reach for Ian, but he falls down because of his drunken state. Jimmy offers him to let him sleep on the couch. When Lloyd wakes up in the middle of the night and decides to look for Ian upstairs with nothing but his boxers on he runs into Molly Milkovich while peeing in the bathroom. He apologizes, then continues walking down the hall. He climbs into Lip's bed with no clothes on, believing he is Ian. Lip reacts loudly, saying that Lloyd has a boner and almost beats him up until Fiona walks in to intervene. Lloyd looks around and then says he was looking for the bathroom because he was going to take a shower, trying to hide the fact that he was looking for Ian. Jimmy takes his dad downstairs, and Fiona asks Lip if he was sure Lloyd had a boner, leading Ian to admit that Lloyd had been looking for him and that the two have been dating. He adds he did not know Lloyd was Jimmy's father when he met him at the club.
Lloyd later asks Ian if he could break into his house to steal back his belongings since his soon-to-be-ex-wife changed the locks. He enlists Mickey and a couple of his cousins to do it.

Ian is still so bothered by the fact that Mickey is getting married to a woman that he starts to drink heavily, getting very drunk just before the wedding. He tries to confront Mickey again, pleading him not to go through with it. Mickey says it is just a piece of paper, but Ian does not think so. They have sex, and Ian tries to stop him from going through with the ceremony again, but they get interrupted by Mandy, who has been looking for Mickey, who then proceeds with the wedding. Ian continues to drink all through the ceremony and the party. He ends up calling out to Mickey and calling his wife a whore. During his ranting, he inadvertently reveals to Mandy that he and Mickey have been sleeping together. Lip tries to take Ian home, but he stumbles and passes out in some bushes.

Mickey tries to talk to Ian, but he tells him that he is enlisting. Mickey tries to persuade him not to leave, but still fails to express his feelings.

His appearance and behavior are different, he wears a glittery top and makeup, and he acts as though he is on drugs. Upon seeing his siblings, Ian approaches them very enthusiastically and acts as if nothing had happened. He appears manic, offering them drinks and seeming very distracted. He does not answer Lip's questions, but informs him that he has been working at the club for two weeks. He also comments that he finds the idea of the army police searching for him "hilarious", and that he did not "steal anything", he just "started the rotors". Lip tries to get Ian to talk outside, but to no avail; he is dragged away by security and Ian does not seem to notice. Debbie expresses concern for her brother, asking if there is something wrong with him. Lip tells her that at least they know where he is now, and says he will check on Ian again soon.

She is concerned over his disinterest in returning back to school. Svetlana tells Mickey that she has kicked out Ian and Mickey comes to the Gallagher home to talk to Ian. After Fiona casually mentions that Ian is upstairs, Debbie, Carl, and Lip follow Mickey. Ian is ambiguous over what he has been up to, attributing joining the military to "relationship issues".

Mickey cannot get him out of bed, and asks the Gallagher's for their help. Debbie and Carl immediately recognize the symptoms Ian is exhibiting. Fiona later comes to the Milkovich house to see Ian. The family comes to the conclusion that Ian is having serious mental health issues, and is most likely bipolar like his mother. The season ends with Mickey refusing to let Ian have any psychiatric help and insists he will take care of him himself, though this is most likely out of lack of information than Frank's similar reaction to Monica submitting herself to a hospital for her illness.
In the season 5 premiere, Ian is at the Milkovich house and is helping Svetlana with Yevgeny. Ian is running with Fiona and she asks if he has seen the doctor from the clinic, to which he replies that he "feels good" and that he doesn't need to go.

Ian and the family are at the diner where Fiona works, when again, Ian notices one of the male employees watching him. The employee goes to the bathroom and Ian follows him. Once in the stall together, the employee gives Ian a blow job. These are all signs of Ian's increasingly reckless and impulsive behavior, which can be attributed to his bipolar diagnosis.
In I'm the Liver, Ian is getting ready to go to a soldier's funeral. At the funeral is a church group who is holding an anti-gay protest. After enduring their endless chanting (which is disrupting the funeral service), Ian becomes furious and begins to scream and swear at the group, threatening to kill them with a wooden cross that he took from someone's grave.
Ian has just arrived back to the Milkovich house with Mickey and is still furious about the protest and searches for grenades and fully automatic weapons. Then Ian and Mickey have some friends over (gay guys) and they argue about who's gonna do something (i.e. a blow job). All of them say no, then Ian says "I'll do it" to which Mickey responds "No, you will go overboard and kill the son of a bitch." Then Mandy and the Protest leader are on the couch and Mandy is flirting with him. She tries to convince him to let her give him a blow job. He agrees, but then closes his eyes, which puts the plan in action where one of the guys gives the protest leader a blow job instead of Mandy and then they take a picture and post it all over the web.
Ian continues to display erratic behavior as the season progresses and things come to a major halt when, Ian disappears for a full night during which he agrees to be in a porn, having unprotected sex. Mickey finds out and is furious, more importantly he realizes that Ian is sick and not making good choices. Ian refuses to accept his conditions and kidnaps Yevgeny, going on a road-trip. However, Ian goes off to a gay bar and leaves Yevgeny is a hot car (again not making good choices). A woman notices and calls the police, Ian takes Yevgeny, however, he is taken by the police when he displays erratic behavior. Lip and Fiona tell the police Ian has bipolar disorder.

When Mickey and Fiona go to visit Ian, he is out of it, and distracted. His therapist interviews him and asks him questions, which results in the therapist clinically diagnosing him with bipolar disorder.
In South Side Rules, Ian tells Sammi all the things he did when he was still in the army. Ian tells her about how he is still wanted. Later on, Mickey and Ian go to the field where they had sex at a couple years ago. Ian starts opening a beer to drink. When Mickey tells him not to drink, because drinking on lithium can cause you to get drunk quicker, he gets angry and punches Mickey across the face. He states he wanted the "shit talking, bitch slapping piece of southside trash he fell for". Mickey gets mad and pushes and punches Ian, which is what he wanted. They begin rolling on the floor fighting, and when they stop, they begin laughing. They both start to drink beer. Later, Ian is completely drunk after drinking just one can of beer. Mickey and Ian are happily dancing and singing in the streets. Ian realizes they've never been on a real date. Mickey asks to borrow a shirt before they go on a date. When they walk in, Sammi tells Ian he's a great kid who will be going places, but he will have troubles ahead of him. Mickey and Ian look at her weirdly and two army men come out. Sammi called the army and told them about Ian. Mickey and Ian try to fight off the army men, but they had guns with them. Ian gets taken and Fiona is on her way back home. Mickey and Fiona are yelling at the army men, but it is no use.

He is released later, he reunites with Mickey before he watches him get chased by a vengeful Sammi and shooting at him since he tried to kill her. He soon reunited with Fiona and V before they watch the scene and the cops take both away.
Ian is still struggling with his condition and still appears to be distant and withdrawn from surroundings; although he visits Mickey in prison, he seems disinterested in continuing their relationship (given that Mickey will be in prison for almost 8 years). He briefly re-encounters and helps Mandy (who is now working in an escort agency), and though he fails to convince her to find a better job, he reassures her that he is still her friend.
During The F Word, Ian tries to save a woman from a burning car but is nearly suffocated himself though is saved by a fireman.
Following this event Ian spends most Going Once, Going Twice, seeking out the fireman who rescued him to thank him.
In Refugees, Ian tracks down the firefighter who saves him. He finds the firefighter who is named Caleb. Ian stays to have fun at the game and encounters Tony Markovich who he greets with a hug and is shocked to see he is gay. Ian later comes onto Caleb who rebuffs his advances and calls him childish. Caleb tells Ian that he is interested in him but tells Ian that he would like to go a date with Caleb. This surprises Ian since Caleb was different from his other partners.
During NSFW, Ian begins dating Caleb however, the date does not go particularly well but gives Ian a perspective on a real relationship and he calls Caleb for another chance. He tells him that he is thinking about becoming a firefighter as well.
As of Pimp's Paradise, they continue to see each other despite this and become closer; Ian even is Caleb's date to the sister of Caleb's wedding. However, Ian is insulted that Caleb wants to show him off to his homophobic religious father but after Caleb apologizes things go better and both enjoy tormenting Caleb's father.
In Be a Good Boy. Come For Grandma., the pair start officially dating, and Caleb introduces Ian to his old friends and ex-partners. During the night, both decide to reveal a "skeleton in their closet", hoping to clear the air. Ian reveals he is bipolar, Caleb reveals he is HIV positive due to a guy who lied to him in college, but they use condoms as Caleb's doctor said he cannot infect anyone. This also leads to Caleb saying Ian should get tested. Ian does, and goes to the doctor with Caleb, and his results are negative. The nurse also asked Ian how many sexual partners he had had, which led to Caleb leaving the room because Ian did not want to reveal that to Caleb. Later Ian tells Caleb that he truly did not know how many because he used to dance at a strip club "and worked the back of the house as much as the front". Caleb seems to be okay with Ian's past.
Along with all this going on, Ian is working to be a firefighter and passes his EMT test with flying colors with the help of Caleb, but is distressed when he gets the paperwork and realizes he won't be able to be an EMT because of his Bipolar Disorder, but Caleb convinces him to lie on the paperwork. Ian gets a EMT job and has a good first day but then his boss runs a background check on him and finds out about his stay in the mental ward. Ian tells her that they wouldn't hire him if he put that. She tells him she can't employ somebody she can't trust. Ian is then fired. However, Caleb convinces him to go back and make a case for hiring him in spite of his disease.

She does so, with the stipulation that he will be sent home if he starts showing any abnormal behavior. Ian agrees and rejoins the team.
After Frank ruins Fiona's wedding to Sean, Ian joins Debbie, Carl, Kevin, Veronica, Svetlana and Caleb in taking revenge on Frank by kidnapping him, driving him to a bridge over the freezing Chicago river, and dumping him in.
As seen in Hiraeth, Ian still works as a fireman, he continues his relationship with Caleb but one morning, Caleb tells him he is going to meet an old friend. Ian gets suspicious over that friend's being a female. He has a chat with Rita and Rita tells him gay men are likely to cheat. Ian does not think so, as he has never cheated on Caleb. At home, he and his brothers are not too surprised when it is revealed that Frank survived the fall and returns home but is not welcomed back. Like his siblings, he wants nothing to do with him. Along with Lip, stalks Caleb on the train. Ian sees the girl, and Lip wants to go back. But Ian wants to see the scene completely.

Ian's protests are ignored and he watches his brother go with Frank. Later on, he confronts Caleb on his affair but the latter admits to being bisexual. Ian then breaks up with Caleb for not being honest with him. He goes home, only to find the walls were blocked with cement, courtesy of Frank getting revenge on his children for trying to kill him and kicking him out. Ian was not pleased by his father's act. He and Lip teased Carl for his circumcision but stop after he tells him that it already hurt without them making him feel less like a Gallagher. That night, Ian and his siblings try to get rid of Frank but he maintains his stance and drops a raccoon to torture them. Ian is woken up by Lip and it to run from the raccoon while Frank taunts them for their treatment of him. Eventually he and Lip get Carl some pain medication and later on they destroy the walls of cement wall while Frank flees the house.
In Home Sweet Homeless Shelter, Ian tries having straight sex but fails. His break-up triggers his manic episode, something Fiona and his boss have to get through to him. Due to this, he takes a break from work. He is not too pleased when Fiona lays down ground rules to earn a keep in their house. When Veronica appears to tell them something about Frank, Ian sees Frank has opened a homeless shelter in a empty house not far from the house. Ian protests his father's choice but Frank tells him along with his other children (except Liam) to leave him alone since they have shown him how they feel (throwing him off a bridge and insulting his since his return) and they leave.
When he returns, he meets Trevor and takes an interest in him, as he seems like the opposite of Caleb in character. He confesses to be a transgender man. Ian unintentionally offends Trevor with his ignorance. Ian apologizes. Later on, Ian introduces Trevor to his father. Trevor initially likes Frank because he believes Frank is trying to help the community by opening a homeless shelter.
As the seventh season progresses, Trevor introduces Ian to some LGBT+ friends. Ian starts to learn that the world is not only black and white and gray and he is also falling for Trevor, sensing that his feelings are not mutual this time. But luckily, Trevor kisses him during a party. After this kiss, both of the guys discuss and seemingly both of them have worries. Trevor thinks Ian is afraid to date a trans man. Ian thinks that they only kissed because they were drunk, and that there was nothing special about it for Trevor. This discussion ends with the two kissing again in a "friendly" manner. Ian now wants to sleep with Trevor but he is confused about how to approach him and he wants Kev's help. As a straight man, Kevin gets more confused than Ian so he cannot be of much help. Ian tries to act normal when he is with Trevor but he cannot help ending up weirdly. This overall weird condition lasts till Ian loses an injured woman and goes to Trevor's house for comfort. Since Trevor is the only person Ian has wanted to tell about the incident, the two characters are about to have sex. However, they both want to top, therefore they cannot have sex at the moment, and they laugh about it. After some time they manage to have sex.
Ian and Trevor become an official couple and Trevor comes to realize the "true" Frank. Ian continues to keep Frank out, even attacking him to force him to leave. Eventually, he mellows out after Frank fixes up the house and helps Liam enter private school; he also permits him to walk his brother to school though threatens him with a bat after pepper spraying him.
On a date, Trevor refuses to go to a bar in which they ask for IDs. Ian suspects he is underage. He says he still uses his ID which he got before his operation. He does not want Ian to see his old photos with long hair, etc. The two have a sad dispute and Monica, who has been with them tries to calm Ian down. Ian does not listen to her, saying "You just appear in no time and ruin our lives," and leaves Monica with Trevor. Then we see Trevor with Ian, now he volunteers to show his ID to Ian. Later, outside the Gallagher house, a detective informs Ian, Trevor, Fiona, and Lip that Mikhailo "Mickey" Aleksandr Milkovich escaped from prison. Ian promises Trevor that he will not get involved with Mickey again. The next morning, a stranger bumps into Ian on his way to work and continues walking. Ian then hears a burner phone ring from the ground, apparently dropped by the stranger. Ian answers the phone and is greeted by Mickey asking if Ian missed him. He then tells Ian to meet him in an hour and to drop the phone in the sewer. Ian initially goes to work like normal, but tells Sue that he is sick and leaves. Ian then goes to the meeting place, where he is blindfolded and forced into a van. Ian is taken to some high school bleachers where Mickey is waiting for him. Ian is initially shocked to see Mickey, but quickly becomes angry that Mickey had him blindfolded and kidnapped. Mickey, in turn, is mad that Ian was late. Mickey sees Ian's uniform and notes that Ian "went all official," and Ian informs Mickey that he now works as an EMT. Mickey then asks Ian if the police talked to him, and Ian tells Mickey that he did not snitch. Mickey then tells Ian that he plans to get a fake ID, some cash, and flee to Mexico with his cellmate and asks Ian to join them. He tells Ian to think about it, and leaves another burner phone for Ian. Ian asks Fiona for advice by asking what her life would be like if she went away with Jimmy Steve. Fiona tells him that she is proud of him because he improved his life and that Mickey would ruin his progress.
Ian ultimately decides to meet up with Mickey that night. Mickey tells Ian, "I knew you'd come," and kisses him passionately. Ian initially returns the kiss, but soon pushes Mickey away. Ian tells Mickey that he's "got [his] shit together now" and even has a boyfriend. Mickey seems unfazed and asks, "Then why are you here?" Ian initiates the kiss this time, and the two have sex at the docks. The next morning, Ian wakes up in the van cuddling with Mickey. While Mickey is still sleeping, Ian leaves a message on Trevor's phone saying he misses Trevor. Ian then wakes Mickey up to let him know that Ian has to leave for work. Mickey asks if he will see Ian again, and Ian takes the unlit cigarette out of Mickey's mouth to kiss him before replacing the cigarette and leaving.
Ian meets up with Mickey again before Mickey plans to leave. Ian still has not told Mickey if he plans to go to Mexico with him, so Mickey asks, "Is this goodbye?" Ian answers by tossing his bag in the front seat and getting in the car.
On the road, Mickey pulls the car over and tells his cellmate to get out of the car so Ian and Mickey can have sex. Later, when they stop at a gas station, Mickey and his cellmate go inside the store while Ian stays in the car. Ian hears gunshots and sees Mickey and his cellmate run out. Mickey is angry at his cellmate for trying to rob the store, so Mickey and Ian ditch the man when they steal a different car. Mickey later plans to rob a store in Texas so they can get some money, but Ian convinces him to go to a bank instead. The two enter the bank and Mickey thinks they are going to rob it. Ian passes a note to the teller and asks her to read it. Mickey is surprised when the teller asks Ian if he is sure he wants to withdraw all of his money and close his account. Ian tells her he is sure, and the two leave the bank with a sizable amount of cash. Ian accompanies Mickey all the way to the southern border. There, Ian tells Mickey that he loves him, but "this isn't [him] anymore." Ian gives Mickey the money, and Mickey gives Ian one last kiss before crossing the border alone.
In the finale Requiem For a Slut, Ian is given update on his mother's death and later confesses to Trevor that he has been with Mickey and Trevor only suggests to attend Monica's funeral. Before the funeral, he meets and watches his grandfather Bill Darrgen fight Frank and is surprised by the display.

He still works as a firefighter and he seems to be continuing his BD treatment. As of the second episode, he seems like the only Gallagher that misses his mother. He and his siblings also believe that Frank has lost his mind after he smoked most of the meth and decided to change by getting a job.
In Where's My Meth?, he talks to Carl about their mother but seemingly the methamphetamine matters to Carl more than their mother. They go to the storage unit to get something of Monica's. However, due to drug-dealing both brothers got into trouble when they are threatened by man named Eric Stark who owned some of the meth and chases them. They manage to elude him and return home.

After Liam and Frank (who had decided to change and experienced guilt) appear to help, Ian and his family are forced to dig up Monica, since Fiona put her share of meth in the ground with her. Ian wanted to pay respect to his mother after her body fell out. The family soon gather the items and arrive at the storage unit to pay Eric, Ian hands Eric some money but its still not enough and Eric threatens them at gunpoint. Ian safeguards Debbie and Liam in the time. Fortunately, Frank steps in and Ian watches as he successfully intimidates Eric to accept the payment or be faced with death if he ever comes near the family again.

While Ian continues his life in Fuck Paying It Forward, he learns about Lip not getting action with ladies and Sean being back in Fiona's life. He sees Frank is still trying to change and is surprised when the latter gave Lip helpful advice.

He watches as Frank does just that. Ian is surprised by his father's continuing change and calls him "Saint Francis" as he bonds with Franny.
As the season progresses, Ian admires Trevor's helpful personality. He, himself, wants to help the kids too. Ian and Trevor need to find shelter for the kids. They find an abandoned church. Ian needs money, so he tries to blackmail an old visitor of Fairy Tail but it backfires as this rich man's wife knows about Fairy Tail. She invites Ian inside and demands oral sex from him.

Ian intervenes and asks the dad if he wants his "ass, kicked by a h-o-m-o-s-e-x-u-a-l". The dad stops, calling his son and some other homosexual people follow Ian and Trevor, out of the Church.
