Fear the Walking Dead confirmed that its final season, season 8, will include a large time skip, but this could cause the series some flashback problems it has already encountered. Time skips on their own can be a risky tactic in shows for several reasons, including the careful casting of older actors for beloved characters, making sure the series protagonists remain consistent, but not static after the time jump, and ensuring that storylines are not warped. But for this series in particular, a time skip may cause some issues after the show has already used a time jump in Fear the Walking Dead season 4 which caused problems for the show.
