Anybody find it funny how little we know about Sean compared to how much we know about Samantha? From what we do know, I sort of think she needs a new boyfriend. I mean, this is a guy who does drugs in the third book! He's not really a major character, but from what I've heard about him, he is not the sort of guy I'd be dating.
I hope that in coming books we learn some more about him, though. I really want to like him as a character, but it's hard.
However, from the first three books, they seem pretty darn cute together.
