A) Scars, no idea how they all could do that to their backs, unless one of the others was directing them? Yeah, that one baffled us also.
B) I believe she was abducted, the books were her just pulling in stuff by the names she already had. We have no evidence that she was no abducted.
C) Bracelet was in leiu of being institutionalized after some action. Was it the scene where she had the knife when the parents found them in the house?
D) I don't think it disappeared so much as she just took off with it, maybe she is what drew the cops to the school?
E) Doors, no idea.
F) The $2000 was money she had to authorize the lawyer to pay off the rehab clinic he died in, I think. That was the last thing left to settle the estate , after which she would receive the balance of the life insurance policy, that was the 50K, what was left of his insurance policy after the estate was settled.
I agree, it's pretty muddy, some of it, but I still enjoyed it.
