Shameless Wiki

This page is about the US incarnation of Debbie Gallagher. For the UK version, see Debbie Gallagher.

Deborah "Debbie" Margaret Gallagher is a main character. She is the third youngest Gallagher sibling. In the very beginning of the series Debbie is described by Frank as being "sent from the gods." However, we soon learn that description is a bit of an exaggeration. Except not by much because she is extremely mature and grounded for her age, so much so that she has trouble relating and socializing with kids in her age group. However in an ironic twist as Debbie gets older she becomes more immature, immoral, self-centered, egotistical, perverted, and delusional, in other words like Frank.

Throughout the Seasons

Season 1

Debbie is introduced as having a very kind heart and is very persistent. She places a pillow under her father's head when he is passed out. She takes Liam to school with her in the Pilot since nobody can take care of him.

She looks really hard to find Frank when he's missing in Canada in episode 2, Frank the Plank. After his return, she talked to him about his trip and was amazed by the sights he saw while gone.

In episode 3, Aunt Ginger, she is devastated about her late Ginger Gallagher and that she could never meet her. Debbie is the one who cares for Aunt Ginger, who is really an elderly woman that Fiona and Frank borrowed from Veronica's nursing home.

Following Ginger's return to the nursing home, Debbie steals little Casey Casden, a neighborhood boy who she takes after witnessing his father playing with him and his sister in their yard and she gets jealous. She is forced to return him to his home through a carefully devised plan to return him so nobody gets in trouble. She is a main pawn in the planning of Frank's fake funeral to outrun two men whom he owes $6,000, which is done successfully.

Next, in It's Time to Kill the Turtle, Debbie finds her father at the park while he was struggling to stay sober. After she gives him sugar, he is excited and asks for more. Debbie loves the new sober Frank, with whom she bonds with over sugar, which he uses to escape his need for alcohol in order to get $3,000 in a medical study. Debbie is very pleased when Frank does work around the house by cooking and telling stories. However, Lip advised Debbie, Fiona, and Carl to "enjoy the moment while it lasts." While Carl doesn't understand Lip's reason, Debbie does and tells him that she will enjoy the sober Frank for the time being. She's the one who ends up encouraging Lip and Fiona to "kill the turtle" as she put it, a misunderstanding to the reference that Lip had made about Frank previously. She decides to end his attempt at staying sober after he plans to slam holes in the roof through the attic for skylights with Carl.

When Monica arrives home in But at Last Came a Knock, she's initially reluctant to accept Monica's apology, but she eventually does, until she gets serious about taking Liam, which is when none of the kids support her apology if they ever did to begin with.

In Nana Gallagher Had an Affair, Debbie watches as Monica takes over as a caretaker for the kids and scrambles at the stress of doing so but is happy to have her. At the Alibi, she is with Fiona, Lip, and Carl, as they find their father, she watches as Frank tries to shoo them away as well Fiona and Lip informing Frank that he is Liam's biological father. When Frank looks to her for help after he is criticized and punched, she shakes her head and leaves with them. At dinner, when Lip reveals that that Ian is not Frank's son, Debbie is surprised and questions if they are still related, which Fiona assures her. Debbie's question is answered as she watches as Ian goes over the test and it reveals that he is the child of one of Frank's brothers, making him both the half-brother and cousin of the family. Debbie is surprised that she has uncles while Fiona states she has three.

In Daddyz Girl she signs Monica up for her classroom mom's group, but since she has once again left the children she convinces Fiona to go, where Fiona befriends Jasmine Hollander. It is Jasmine who drives Fiona and Debbie to the police station when Lip and Ian are arrested driving a car Jimmy lent them, and the two spend the night sleeping in the waiting room of the police station. She's the one who discovers Jimmy/Steve's double life, something she knows is wrong and pushes very strongly despite both Veronica and Sheila telling her she should leave Fiona to deal with her own relationships. Throughout most of the season, she is either looking into Jimmy's past, visiting his house, or harassing Jimmy about the lie he's living, frequently encouraging him to tell Fiona the truth about himself.

Season 2

Debbie has grown up a bit as she's running a full-fledged daycare out of her home on her own, with the money she earns going into the winter Squirrel Fund. She ends up with a stress rash, which she attributes to being from melamine-tainted laundry soap she bought at the Dollar Store. In reaction to this, Fiona forces her to throw a party, at which she invites Simon, a boy who has a crush on her whom she only invites so he'll invite Holly Herkimer, a girl several years Debbie's senior who is still in Debbie's grade and is said to have HPV, in addition to Lip, Ian, Carl, and Carl's friend Little Hank, who she is thought to have a crush on throughout most of the season. She goes to Lip and asks him about what he liked about Karen, so she knew what to do to make Little Hank like her. His response was that it was about pheromones, so she dressed in Fiona's clothes and went to Mandy for help with makeup.

Debbie also ends up obsessed with death after seeing the dead body of Aunt Ginger's boyfriend Harry at the end of Summer Loving. After this traumatic event, she ends up thinking about it constantly for a whole episode and doing a hilarious rendition of #1 Crush by Garbage.

She continues running her daycare until Grammy Gallagher arrives to the house in Can I Have a Mother. Debbie is confused as to who the old woman is but is surprised to learn that she is her paternal grandmother. However, she is more than happy to keep her secrets after being handed a $100 bribe.

In the next episode, Debbie spends more time with her grandmother, who ends up spoiling her by giving her a laptop when she is sad. Debbie is delighted with this and thanks her for the gift.

Debbie is happy to have her at the house until Peggy's activities in the basement is revealed and Fiona finds out Carl was nearly caught in a meth lab explosion. As a result, Fiona kicks Peggy out and she goes to live with Frank and Sheila while Fiona prohibits her younger siblings from seeing her, to their sadness.

Season 3

Debbie finally begins to lose her liking of Frank in this season. When Frank returns after several months of his absence, she is initially ecstatic to have been back and is the only member of the family who is willing to let him in he house. However, when he crushes her school project that was very important to her, saying "It was a piece of shit anyway", Debbie takes out a pillowcase that she filled with hard soap and starts hitting Frank with it while screaming that she hates him and "to get out of her house."

Later on in Season Three she is riding home from the grocery store on the bus with Fiona. She catches a full-grown man on the bus masturbating to her. She freaks out and Fiona calls the police after driving the man off the bus. While Ian, Carl, and Lip go to find a nearby pedophile to beat up, Mandy tells Debbie that she is going to teach her how to defend herself the Milkovich way. Then she gives her a weapon. While Debbie is practicing this outside, she meets Kevin's alleged son, Dominik and hits him with the weapon. He is shown falling down in pain and Debbie interrogates him into telling her who he is. He says he might be Kevin's son and then asks if he could find something to smoke around their neighborhood. They are later shown on the playground hanging out together while Dominik asks questions about his father and Debbie asks questions about sex and if she should become a nun and never have sex. He says she's to pretty to become a nun and kisses her, Debbie's first onscreen kiss.

At one point, Debbie expresses her desire to go swimming at the city pool. Frank tells her it's a bad idea because "at the city pool there are city kids." Apparently one summer, these city kids ripped Debbie's bathing suit to which she says they were just trying to make it into a bikini. Frank then tells her that if those kids will do that to her while running through the sprinklers in her own front yard, just imagine what they might do with an entire body of water at their disposal. Ultimately, Frank will not allow Debbie to go to the pool until she is able to hold her breath for ninety seconds, saying that if she can hold her breath that long that it will be long enough for her to get out of any trouble should she ever find herself in it. Debbie soon is able to hold her breath for over one hundred seconds, ensuring her ability to swim at the city pool. However, the type of city kids she runs into are not what Frank was expecting, they come in the form of young pubescent girls with whom Debbie attends school. They tease her for her childish one-piece bathing suit, ask her if she's a lesbian, and tell her she should "grow some tits." The next time Debbie goes to the pool she sneaks a white bikini from Fiona's drawer and adds extra padding on top with some socks. She bravely goes for a dip in the pool, and she comes back to sit at her chair and read a book. However, this moment of bravery was short lived as someone put ketchup on the chair Debbie was sitting at, and the girls scream at her, "period! period!" and everyone laughs. A humiliated Debbie rushes home and locks herself in her room and sobs. Fiona tries to console her by telling her that, "Nobody fucks with the Gallaghers." Debbie gets the courage to go back to the pool and this is where her ability to hold her breath pays off. She fills two bags with sand which she uses as a weight to hold her down. As one of the girls who humiliated her is about to get out of the pool, Debbie grabs onto her leg and holds her underwater until she passes out. She's quite happy with what she accomplished and runs back to the Gallagher house, screaming, "That's right! No one fucks with a Gallagher!"

Season 11

As of This Is Chicago!, Debbie was eventually caught by the cops and arrested. In court, Julia testified against her about the details of their fling with Debbie being sentenced to probation along with having to register as a sex offender. In the six months that have passed, Debbie is now wearing an ankle bracelet and has continued seeing Sandy. While home bored, Debbie received a break when she is given her truck for wielding. She is annoyed by Sandy and Liam making fun of her slogan on the truck. Debbie is also annoyed by others defaming her as a sexual predator now that she is not being recognized on the website, especially since it made a mistake of Julia's age. Debbie eventually gets this error corrected. Soon Sandy points out something new by boosting up her reputation on Instagram of being falsely accuse and realizes that she will get hired soon. She later goes to Lip and Tami's house for a party and has fun. At the end of the episode Debbie is in bed reveling in her reputation boost, Sandy soon walks in role-playing before the two have sex.

After learning that Sandy holds secrets about her family, including a son and husband, tensions rise between the two. Debbie follows and tracks Sandy for the information, and tries to convince her to keep Royal around. She is concerned Sandy ran out on her kid and states she would not do the same to Franny.

Heidi threatens Debbie to hug her as to not blow her cover and the two hit it off, robbing cars etc. together. At the end, they become girlfriends, as stated by Carl, and Heidi invites her and Franny down to Texas for a 'promising opportunity'.


Debbie is a sweet, spirited, smart, kind-hearted girl. She has deep trust and loyalty towards her family, though she tends to be extremely naïve. She lived for years with the hope of having a good father in Frank, hoping he may one day change. She showed genuine concern and care for her father when no-one else did. Though, she is capable of unconditional love, she demanded love from Frank in return, only to be disappointed by his selfish, uncaring nature. When asked if she ever wished Frank dead, she confirmed it. Debbie has, or at least had, a great deal of respect, trust and love towards Fiona, who was her closest sibling and only sister. She always supported her in house and often took care of Liam.

She was originally greatly mature as she could explain a confused Carl how lesbian sex works in season 1. She holds great resentment for her mother for leaving, even despises her. This is evident through Debbie, when she first saw Monica in several years, pushing her away and running home, as well as her attempts to take Liam and "start her own family". Though her hatred is lesser than Fiona's, due to Debbie's last days with Monica being of a mostly positive nature since she helped in getting her daughter back. She loves Liam deeply, whom she spends most time with, and began to cry when Monica announced that she wanted to take Liam with her. She was upset about her great aunt's death, despite never meeting her.

Her relationship to Frank is very complicated. It shows her ability to daydream at her maximum when she tolerated him most, as well as doing little acts of kindness like putting a pillow under his head when he's passed out, or making him breakfast. She never receives more than a smile from him, and only when he's in his rare sober states. This frustrates her to the point where she stole a baby that had a father who plays with him out of envy. She prayed for his safe return when he disappeared and even posted pictures of him at their house's fence, or hugging him tight at his return. She tried to talk and play with him, even when he expresses open disinterest. Her concern for her father ultimately died, when Frank destroyed her school project, calling it "a piece of shit". She had a frustrated rage in which she beat him with a bag of soap, screaming in sadness and frustration. Afterwards her relationship to him cooled down, once she finally understood that Frank will never change. Though, she continued to spend time with him, she lost most of concern for him but still loved him when she told him after his liver failed. After he supported her in her pregnancy, she was grateful and named her child after him as gratitude even calling him "Dad" again. When he ruined Fiona's wedding, she took part in throwing him off a bridge for it and casually told Lip that she believed Frank dead. After seeing that Frank survived being thrown off the bridge, she was not pleased and showed him nothing but contempt in his moment of pain. She went as far to rename her child to distance them from him and warned Liam of the disappointment he was in for with Frank. She was also annoyed by him getting revenge on the family for their acts and treatment. Despite that, she would attempt to reconcile with him, for she needed his help when risking losing her home and child. Although he refused, she got him to comply by changing her daughter's name back and he gave her advice. The next time she went to him they argued, she let him stay with her and her boyfriend along with Monica. Debbie was also moved by Frank calling her and her siblings strong, with them making amends. She was very surprised when Frank decided to genuinely change in Season 8, though she was put off by his new actions. She was speechless at him defending her and her siblings from a meth head by threatening the man with death if he came near them again, as she realized her father held back on her attacks on him. While she was grateful, she still believed that he couldn't truly change himself but humored him as he went on and smiled at his progress as he was doing better. When he injured his leg, she was forced to care for him along with her siblings and was annoyed by his complaining. She loudly told her father that nobody loved him, but this was far from true as she had hid his medicine from him to prevent him from overdosing, let him watch her daughter, and found a caretaker to tend to him, showing Debbie was just irritated by his whining and does love him.

In her teenager years, she grew obsessed with boys and sex, probably an influence of living in a house hold with her extremely sexually active siblings, mainly Fiona. This was also a part of her compulsive heterosexuality as she felt being with boys made her a real woman that fit in.

She has darker, reckless, manipulative and arrogant sides to her personality spectrum as well, and lived out delusion, cynicism and frustration. She happily kept her grandmother's secret of a gun and finger after being bribed. She also tried to prevent Fiona from discovering their grandmother's meth lab. She doesn't take no for an answer, as after her first boyfriend refused to have sex with her due to the difference in their age, she took advantage of him while he was drunk and had her way with him. She expected him to be fancy with her afterwards, although it clearly contradicted his prior behavior. Her second boyfriend was her age and they understood each other well, yet she drifted into a daydream again. She grew obsessed with creating her own "happy family" with him (once again being extremely delusional, naïve and arrogant) , the total opposite of her own family that she grew up with and started to resent. She recklessly tricked Derek into making a baby with her, without asking his opinion or permission, or even knowing his own dreams and desires. This might be her most selfish act, as she casually changed the lives of them both, simply out of her own desire to have a family and expected everyone to simply play along. But she loves her daughter regardless of her unfulfilled dream, even if Franny means that she will have to live out an unsatisfied and unfulfilled existence because of her. She has great resentment for Derek for abandoning her and destroying her delusional dreams, and shows little understanding for his personal motives, calling him a "deadbeat". Her relationship with Fiona is also somewhat cold, as she lets her frustration out on Fiona, resenting her for her selfish nature once the children are older. She is unhappy with Fiona who repeatedly told her to give up her pregnancy. Debbie begins stealing to resell valuable goods to care for her baby.

In season 9, Debbie starts to explore her sexuality. She met Alexandra while she was protesting fair wages for all genders. The two hung out and soon they developed feelings for each other. This was something new to Debbie as she never really had any interest in girls. However, she continues the relationship with her despite how confused she was. She asked Ian how he knew he was gay. He said he knew because he was having sex with a man. When he asked her why she tells him that she might be gay. Ian instantly scoffs and tells her she's not gay. The two talked but by the end, neither of them had any more of a clear mind. After just spending a few nights with Alexandra the two decide to move in. This showing that the two are high on love. However, after the two talked about their past, it becomes clear to Alexandra that Debbie is not over guys and that she is not sure if she straight, bi, or a lesbian. Debbie tells Carl that she's in love with a girl. Carl also does not believe that Debbie is gay because she has a baby. Debbie tells him that plenty of lesbians have babies. By the end of the day, Alexandra calls it off. "I can't do this anymore, there are too many triggers. I can't fall in love with another straight girl" Alexandra says. Debbie claims she's gay but Alexandra fights back saying for what 2 days. The two break it off and Debbie goes home crying. When her family asked what was wrong she tells them that she and Alexandra broke up. The family, however, had no idea who Alexandra was or the fact that he was actually a she.

Throughout the season Debbie explores her sexuality all while trying to take care of her family. She finally finds herself as a lesbian and eventually grows comfortable in the label. Carl starts to date Kelly and brings her home several times. At first, Debbie doesn't think much of her, just her brother's girlfriend. However, over time the three of them start to hang out a little more. This causes Debbie to develop feelings for her. One day Kelly had fallen asleep on the couch and Debbie finds it beyond cute. She decided to kiss Kelly most likely thinking Kelly wouldn't know. Kelly woke up surprised to see Debbie kissing her and not Carl. She tells her that she's not gay and that she never meant to lead Debbie on. By Season 10, it appears Debbie moved onto a new relationship will be with a woman named Claudia who mistook Debbie for a prostitute until learning otherwise. After overcoming some awkwardness because of the error, the two were able to be a couple. However, things took a turn when Debbie developed a mutual attraction to Claudia’s daughter Julia and they ended up sleeping together. Once Julia was revealed to be using her to spite her mother, Debbie found a new relationship in Sandy Milkovich. Debbie and Sandy were together for a total of six months and were saying happy with Sandy not being bothered by Debbie being a sex offender (although this was just because of her relationship with Julia due to Claudia pressing charges even though Julia isn't even a year older than Julia). However things got turbulent when secrets about Sandy were revealed such as Sandy owning a car having an apartment and working at another job. Although Debbie feel guilty about betraying Sandy’s trust when the latter confronted her but things got worse when Debbie learned that not only was Sandy married but it was to a man. Debbie didn’t have time to confront Sandy on this because she had to watch the latter run away. They eventually reconcile for a short while, but soon Debbie finds out Sandy has a son, Prince, that she chose not to raise as she was 15 when she gave birth, and never wanted a child anyway. This causes their relationship to break apart as Debbie judges Sandy harshly, unable to understand Sandy's choice due to her own abandonment issues and her strong attachment to family.

These issues also cause her to clash with Lip when he wants to sell the Gallagher house in order to make a big profit after he got evicted from his own house. Unlike Lip and Ian, she is strongly against selling as the house has always been her home. Moreover, she is afraid selling the home would mean being alone and loosing her family. He fear of being alone also drives her to look for a relationship, though all of them usually end up in a mess as Debbie has no idea how to have a healthy relationship and has a poor choice in partners. This comes head to head in the finale, when she hooks up with Heidi, a dangerous ex-con, and may possibly leave town with her.

  • She is one of the few Gallagher children to call Frank "Dad".
  • She is the second of Frank's children to have a child, with the other being her half-sister Samantha Slott.
    • Coincidentally, Debbie is the youngest of Frank's daughters while Sammi is the oldest.
  • According to Frank, Debbie's first steps were of her running to her mother at the police station for the latter's first booking.
  • Like Fiona, she earned her GED but got it quicker than the latter.
  • She is missing some of her toes after her foot was crushed and Frank removing some in her sleep.
  • She is a rapist, as she date raped her first boyfriend Matt after he became incapacitated from drinking Frank's homemade beer. She doesn't feel bad about the rape as after she proudly yelled "I am a woman!". She only feels bad that Matt broke up with her. She also kissed a sleeping Kelly Keefe before the latter woke up and admitted her disinterest.
  • She currently identifies as lesbian. She stated this at Ian and Mickey's wedding.
  • She is closest to Fiona, Carl, and Liam out of her siblings.
  • She has had three real boyfriends and three real girlfriends.
  • She is the third Gallagher to be involved with a Milkovich, in her case Sandy.
  • She never interacted with her nephews.
  • She was the last of the older Gallagher kids to be arrested.
  • Debbie's encounter with Julia and Claudia mirrors that of her father's with Karen and Sheila.
    • It's ironic that Debbie is being charged with statutory rape for the first time even though she committed date rape five seasons prior which was much worse considering how shaken up her then-boyfriend Matt was about it when he found out what she did, and didn't report it as Debbie was 15 and it would be more likely that the cops would charge him with the offense as he was in his 20s, while in this case Debbie was slightly manipulated by Julia.
  • Debbie's relationship with Sandy mirrors that of her sister's relationship with Ford, in which both of their partners turned out to be married parents and were living double lives.
