Cassidy (Kassidi) Gallagher, Carl Gallagher's obsessive girlfriend and later "wife" in Shameless , meets a grim fate off-screen in Season 9. After Carl leaves for military school, Kassidi refuses to let go and interferes with Carl's life there, causing frustration among his fellow cadets. One of the cadets tells Carl that they "took care of the problem" and that "they'll never find the body," implying that Kassidi was killed

. The show never explicitly shows or discusses her death on-screen, and her disappearance is abruptly handled without follow-up, which has frustrated many fans. A deleted scene, later revealed by the actress Sammi Hanratty, confirms that Kassidi was killed off-screen-one of Carl's cadet friends sneaks up behind her, covers her head with a bag, and drags her body to a shallow grave

. This dark turn was cut from the aired episodes, reportedly because it was considered "too dark" for the show's later, more sitcom-like tone, despite other violent moments in the series. The handling of Kassidi’s death is widely seen as abrupt and unsatisfactory, with no mention of the impact on Carl or any investigation into her disappearance

. In summary, Kassidi was killed off-screen by a fellow cadet at Carl's military school, but the show chose not to depict this directly, leaving her fate as a dark mystery that was only clarified through deleted scenes and external statements
