Really? You think that'd be the only reason to pick Castle over Demming?

Don't get me wrong: I think both guys are fantastic. Demming is just fucking ... delicious. And he obviously has a lot of respect for Kate, too. But Castle, despite being a bit of a dork, is also very nice and he DOES respect her and what she does. Honestly, I'd be happy with the writing going either way on that: either Kate and Tom or Kate and Rick. *rubs belly*
