I think the "Aaron" that Kate picks up at the end of eggtown is definitely Claire's Aaron.

I don't think Ben would physically rape anyone. It's not his style. He manipulates people. He gets them to do something he wants them to do and make them think it was their idea.

Just look at the way he has manipulated Jack and Locke. Pretty much everything Jack and Locke have done is what Ben wanted them to do.
