Carolyn is such a fool--Burke has no real interest in her, but knows just how to get what he wants. I can beleive that there is real feeling in his come-on to Laura, though clearly she doesn't share it, not at all. In that way, she still seems depressed--I don't think she really feels anything for anyone, except David, but even then sort of an indifferent love for the concept. Roger doesn't like losing at his own game.
