In Paranormal Activity 3 (maybe it was PA 2?) Katie kidnaps Hunter when he was a baby. In Paranormal Activity 4 we find out that Wyatt is actually Hunter. How is this so? If Katie took him, why did she give him up only to come back after him? Is there a back story to explain this?
Further more, who is Robby? Was he just there to help prepare Wyatt to convert back into Hunter and "be with his family" ?
