I know CheshireP, I'm curious, to why Rook wanted to become a plumber, It seem that Ben is always in front though. I mean, it is shown that Rook was isolated, did some thing happen that he was rescued, or was it like Rook wanted more out of his life, to do something. this would such a good episode, because we know Ben's past, and yet we know nothing about Rook really. why is he protective of other strangers? He has a great respect for life, and yet he treat evil the way it should be treated.
