Jimmy Lishman, also known as Steve or Jack, had a complex and turbulent storyline on Shameless. Initially, he was Fiona Gallagher's love interest and a charming but troubled character who lived a double life, lying to his wealthy family about his true activities

. By the end of Season 3, Jimmy was presumed dead after being taken on a boat by Estefania's father, a South American drug lord, as punishment for his failed promises to help Estefania with her citizenship. The show left his fate ambiguous, leading many viewers to believe he had died

. This was partly due to the show's production constraints and the actor Justin Chatwin's confirmed exit as a series regular

. However, Jimmy made a surprise return in the Season 4 finale and appeared again in Season 5. His comeback revealed that he was alive but struggling, and his relationship with Fiona was ultimately untenable. Fiona rejected him, realizing they were not suited for each other, especially given his ongoing issues with honesty and stability. After a confrontation with Fiona's husband Gus and a brief rekindling with Fiona that ended badly, Jimmy left for good, riding off on his motorcycle. This marked the conclusion of his character arc on the show

. In summary, Jimmy was presumed dead at the end of Season 3 but returned later to wrap up his storyline, showing that despite his love for Fiona, he was not the stable partner she needed. His final exit was definitive, and he has not appeared since Season 5
