Frank Gallagher

Vernon Francis "Frank" Gallagher (William H. Macy) is the father of six children. He is a deadbeat alcoholic, drug addict and morally deficient freeloader who relies on his children to barely get by. He also swindles the state welfare system and this type of opportunistic deceit has been learned by his children. According to Fiona, since Frank refuses to work and most of them are uneducated, the family lives far below the federal poverty threshold for a family their size. Frank did attend college to study psychology, where he met Monica. They had only dated for about 2 weeks before they got married.

Frank has sex with almost any available woman, resulting in the births of even more children. For instance, he begins a relationship with Sheila Jackson when he discovers that she gets maximum disability benefits for her agoraphobia. Frank is the biological father of Sammi, Fiona, Lip, Debbie, Carl, and Liam, but not of Ian, who is presumably the son of Frank's brother Clayton, making him the children's half-brother and cousin. Despite that, he refers to Ian as his son. Frank is also the grandfather of Chuckie and Francis.

The children do not think much of him and refer to their father by his name "Frank" and rarely address him as Dad, though there have been occasions where they have. Although Frank pontificates self-righteously about political and social issues, he spends most of his time developing schemes to cheat the system and take advantage of others in order to make money. He pays little attention to his children but can display care and concern for them in drastic circumstances.

In season 4, his liver fails, as the result of his chronic alcoholism. He tracks down his eldest daughter Sammi, and although she is not a match for a liver transplant, she and Sheila go out of their way to arrange Frank's liver surgery. They find an unlicensed Bangladeshi surgeon willing to do the operation, using a Bangladeshi donor. The surgeon initially asks for $30,000 but when the two women admit they can only pay $26,000, he reluctantly agrees to operate. With money acquired by Sammi from the sale of Sheila's furniture, along with Sheila's savings, the cost of the surgery is covered. The surgeon makes off with the money and one of Frank's kidneys, leaving Frank with his original failing liver. Nevertheless, Frank is supplied with a replacement liver from the emergency room that allows him to continue drinking. Frank also bonded with Sammi and saw that she was more like the kids than he thought after she shot him.

In season 5, a home beer brewing mishap causes Sheila to leave for good. In episode 9, Frank embarks on a "bucket list" style spree with Bianca, who has advanced pancreatic cancer. They spend Bianca's last days together and although Bianca's thrill seeking is too much for Frank, they end up in Costa Rica. After leaving a note for Frank, Bianca commits suicide by walking naked into the ocean. Frank returns home crying and tells Lip and Ian that Bianca has died.

In season 6, he supports Debbie in her pregnancy and soon reconnects with his ex-girlfriend Queenie (his daughter Sammi's mother). After he ruins Fiona's wedding (even though he told his daughter about her fiancé's indiscretions) the Gallagher kids (except Lip, Liam, and Fiona) and friends, have had enough of him and throw him off a bridge into a frozen river.

In Season 7, he survived the fall and was in a coma for month before he returns to the Alibi and everyone is (mildly) surprised that he survived and he recalls them throwing him off the bridge and is angry. Kev was the only person who felt guilt but briefly. He attempts to go back his house where he learns from Carl that everyone hoped he was dead and Fiona kicks Frank out of the house and the other children do the same. Hurt by this, he "disowns" them and makes a "new" family at a luxurious homeless shelter he created by a scheme, of course. The cops were aware of who he was but couldn't throw so many people out and permit it. Frank sends his real kids away when they try to stop him since they have shown how they feel. Frank is eventually thrown out a window when the homeless patrons find out he's been hiding money they earn. Near the end of the season, he is permitted to return to his old home after he slowly started helping by fixing up the house and getting Liam in a private school. Frank is devastated when Monica dies from brain damage, he is attacked by her enraged father and shares touching words at her funeral before rushing out in sadness.

In season 8, Frank copes with Monica's death by doing all of the meth she bequeathed to him, then having a midlife crisis where he decides to restart his life as a 21 year old, having realized that Monica was the trigger of his alcoholism and bad parenting. As a result, he became sober and went by Francis to disassociate with his past, he cleaned his hygiene up, got a real job, made amends with his family and friends, got a car, and tries to be a more productive member of society. While his children believe Frank has lost it, he proves his change is genuine by protecting his family from an armed meth head who was Monica's partner, which earns gratitude from Fiona. He continues his change by mentally aging himself on occasion and even help more with his children by giving them useful advice. Frank soon bonds with his youngest son Liam and acts more fatherly to him, as he sees Liam as his last chance to be a proper parent and he ends up having fun in their time together. However, when the hardware store chain he is working at shuts down and he is unable to find new employment, Frank starts to fall back into his old ways.^[3]

During Season 9, he is still showing signs of being his old self by sleeping with the mothers of the PTA and secretly stealing from them to pawn their belongings. He is revealed to have given them a series of STD's after he is revealed to be common source. Because of this, his son Liam is expelled from private school and forced to attend public school. Frank also nominates a former congressman Moe White to be city councilor as a part of a scam to earn money, though he comes to have second thoughts after the man is revealed to be a sex-offender. Despite that, things still proceed and Frank gets Terry Milkovich to help him and soon Mo nominated as congressman but Frank is dismayed to see he is up to no good.

Fiona Gallagher

Fiona Gallagher (Emmy Rossum), age 28, is the eldest of the Gallagher children. Because of her mother's absence and Frank's neglect, most of the responsibility for child-rearing falls on her shoulders which forces her out of high school in her junior year. Fiona works a few dead-end minimum-wage jobs to support her five siblings. Though often stressed and exhausted by her responsibilities, she always performs them. Prone to selflessness, she sometimes needs to be reminded to look out for her own happiness. Even though Fiona wants everything under control, she enjoys a little bit of chaos once in a while.

At the close of season 2, Fiona receives her GED and begins to take more interest in jobs. In season 3, after Frank calls social services out of sheer spite, Fiona wins a court case (and with the admiration of the judge) and is appointed her siblings' legal guardian. This strains her relationship with Steve/Jimmy.

Towards the end of season 3, Fiona finally gets a more rewarding job with a cup manufacturing company. In season 4, she begins dating her boss Mike but then has sex with Mike's addict brother Robbie. When Mike finds out he breaks up with her. In the aftermath of the breakup, Liam ingests cocaine that Fiona got from Robbie (a birthday gift; she kept the coke but made Robbie leave) at her birthday party and is hospitalized. Fiona is arrested for child neglect and drug possession. Mike posts her bail and she is put under house arrest with a curfew. When Fiona breaks her probation while partying with Robbie, she is incarcerated with a 90-day sentence. She is released shortly after due to overcrowding in the prison, and gets a job at a diner.

In season 5, Fiona impulsively marries Gus Pfender, the bassist of an indie rock band, and changes her last name to Pfender upon marriage. She then cheats on Gus with Steve/Jimmy when he appears in town once again. After that, she begins a relationship with her boss at the diner, Sean. Her extramarital affair with Steve/Jimmy, along with her budding relationship with Sean, end her marriage. She discovers she is pregnant around the same time as Debbie does, but doesn't know whether the father is Gus or Steve/Jimmy, so she has an abortion and urged Debbie to do the same. By the end of season 6, Fiona and Sean plan to be married, but Frank ruins the nuptials by revealing Sean's drug relapse to Fiona at the altar, causing Sean to leave her.

By season 7, Fiona starts to act more selfishly as she is tired of being unappreciated by her family members, especially Lip, and she is more focused than ever on building wealth. Her boss, Margo, is also a high-school dropout but has amassed a net worth of $300 million; Fiona wants to follow in her footsteps. She sees an opportunity to invest in a deteriorating laundromat and uses the Gallagher home as collateral, which angers Lip. She eventually sells the laundromat to Margo and buys an apartment building.

When Monica dies, Fiona is indifferent, declaring her willingness to have the funeral consist of a bonfire in the funeral home parking lot using the ashes stored in a bag. Although it doesn't come to that, she does bury her portion of the inheritance in Monica's casket.

He created various money-making schemes to help the Gallagher clan survive, such as running an ice cream truck that also sold beer and marijuana. He also made money by taking the SATs for fellow students for a fee, but had to stop when he was caught by Professor Hearst, an investigator from the Educational Evaluation Service. After testing Lip in private, Hearst discovers Lip is one of the statistically very rare students capable of achieving a perfect SAT score and offers him an internship at the robotics lab at the University of Chicago, which Lip turns down. Hearst gets Lip in trouble with his past clients by invalidating all of their SAT scores, since they didn't actually take the tests themselves. In addition to being adept scientifically, Lip is multilingual; in season 2 he exhibits knowledge of Portuguese and Italian and in season 4 he speaks Spanish.

Outside the classroom, Lip spends much of his time drinking beer and smoking weed and eventually participates in car theft schemes with Jimmy.

Lip then starts a new relationship with Mandy Milkovich. They live together from season 2 until season 3; Lip briefly lived at her house and she eventually moved herself in with the Gallaghers. Though Mandy and Lip have an insatiable sexual relationship–he had a plethora of condoms ready when she moved in–he is annoyed with her living with him because he thinks she's turning the relationship into a common law marriage. Lip has trepidation that he possibly got her pregnant in season 2, but in season 4 during one of their trysts, he flippantly recommends her to get off the pill and get pregnant with his baby even though he wouldn't be around to take care of it. When Mandy discovers Lip doesn't plan on going to college, she considers that he is wasting his potential and his chances for a brighter future. When she secretly applies to colleges on his behalf, he is accepted by MIT, among others.
