I agree about Carlisle. I don't know about their future together at all, but yeah-- I do see it is a bit of a disaster waiting to happen, because he is going to fuck her over. I believe he would leave her at some point down the road, his eye caught by someone else. I would allow that he loves her now but that he would love someone else just as easily and just as passionately, and clearly obsessedly, as he does her and that she'd be left in a ditch by the roadside (figuratively, I think) and would probably end up crawling back to Ripley. I don't see her as a very strong, independent person, just one of those women who will always hang on some guy's arm.
