Fuller House sparked a fan theory that suggests Michelle actually died in the original Full House finale. The popular character, played by Mary-Kate and Ashley Olsen, was noticeably absent from the Fuller House revival. The dark theory implies that Michelle's absence in Fuller House is due to her tragic death in the original series. The theory suggests that Michelle's head injury from falling off her horse in the final Full House episodes was fatal. This dramatic twist suggests that the Tanner family's memories and Fuller House's references to Michelle are a way for the family to cope with her tragic death.
