The Walking Dead has the opportunity to bring back Carl Grimes in Rick's upcoming spinoff. Despite being killed off in season 8, Carl can make a return as a hallucination in Rick's spinoff. Hallucinations and dream sequences are common in the franchise, and it would be a fitting way to involve one of the show's biggest characters. Carl's return would serve as Rick's moral guide and highlight his importance in the franchise. This would also allow The Walking Dead to fix the mistake of Carl's underwhelming exit.
