Smape's also got his "If I can't make you care for me, I'll at least make you *notice* me!" attitude. He's pretty hard to ignore, if nothing else.

Peter, on the other hand, doesn't want to be noticed, and is quite good at finding bolt holes. Peter is quite happy to be overlooked.

Actually, I think the most opaque character in the books is Lupin, who says many things, but who acts in quite different ways -- and yet very few readers pick up on how duplicitous *he* can be.
