At first, AngieBelle, that is exactly what i thought happened. That when Kathryn crossed the boundary she somehow lost her memories or got confused and then didn’t know how to drive her car and that was why she crashed or something like that happened. And that she has been wandering around in the woods lost. How long has it been? Five days since she went missing? You could survive that. I really wish Kathryn had said something when Emma found her.
This is still my favorite theory as to where Kathryn has been. Wandering around in the forest confused.
