Yeah the girl shouldn't have been the new Jigsaw. However, if you watch the first one again, if you pay attnetion, you'll notice how they very slightly hint at how she liked being in the whole Jigsaw thing. Remember when she was being interviewed and she said, "He showed me the way" or some crap liek that? All in all, the movie is predictable, although very gross, it's no fun when you generally know how it's going to end.
