That's a possibility . . . I don't know, it strikes me as odd that Norton simply . . . goes along with sex. I'm not saying that casual sex = no emotions, but I find the way that she's written as implicit of that. Of course, I'm bringing my own experiences to the reading, but the only sense of emotion from her that I found to be an insight into the character was the anecdote about Jimmy, just before she tells the other two about Morini. Maybe it's just that I relate to Espinoza and Pelletier better, but either way, in my experience, a person who takes two close friends as lovers in the same time period are generally people I admit, I am more willing to characterize as emotionally distant. But again, as abstractions, what can really be said about the emotional validity of any of them . . .
