Carl Francis Gallagher is the fifth youngest Gallagher child. When he was younger he shared a room with his older brothers Lip and Ian. Carl is seen as a trouble maker in season 1 after almost facing expulsion. In season 2, his love for selling drugs starts when his grandmother Peg convinced him to get prescription drugs to make meth.
Season 3 but he does end up shaving his head due to lice but Frank convinced him that it was cancer, which Frank used to get Carl into a free summer camp. We see Carl’s first love interest Bonnie who lives in a van with the rest of her family but the love show soon ends when Bonnie’s family leaves.
In season 5 he uses his nephew “Chuckie” to deliver drugs but gets caught because Frank notified the police. In trial Fiona wants Carl to grovel but instead he insults the judge and doesn’t name his drug dealer, which lands him a year in juvenile prison.
As of the seventh season, Carl still dates Dominique, but they do not have a good sex life, as Dominique refuses to perform oral sex on Carl, due to his being uncircumcised. But when Dominique gets gonorrhea, her father blames Carl. But Carl finds out that Dominique contracted the STD with someone else. He takes a picture of them together, and gets a test done to prove to Luther, Dominique’s father, that he didn’t give her the disease.
Carl later grows a bond with Dominique’s father who helps him get into military school.
