6. Wyatt Is Actually Hunter (Paranormal Activity 4)
If there's one thing PA4 got right, it's the twist that Wyatt is in fact Hunter, not Robbie. The movie makes pains to have the viewer believe that the troubled, creepy Robbie is Hunter, all the more so considering that he lives with Katie, but in fact, it's to be assumed that Katie put Hunter up for adoption (somehow) and had him live with Alex's family for several years. Katie then moved in nearby with Robbie (whose origin story is still unknown) in an attempt to get Hunter ready for some sort of interaction with Toby in the future.
