Ian Gallagher

Ian Gallagher is a 16 year old boy, and is the third child of Monica Gallagher. It is revealed in "Nana Gallagher Had an Affair" that Ian is not the son of Frank, but one of his brothers. His half-siblings (raised thinking they were siblings) consist of Fiona, Lip, Debbie, Carl, and Liam. Ian works at a Kash and Grab, a corner store.

In the pilot episode, it is discovered by Lip that Ian is having an affair with his Muslim boss, Kash, who's married to his white Muslim wife, Linda. Ian also told Lip that he's only had one relationship before Kash, with a boy in school named Roger Spikey.
