And that's when she raises an eyebrow at him, because that sentence doesn't match with Castiel at all. It's not that he doesn't say nice things, as such, but he's never usually this complimentary. Not without a direct reason, and it's been far longer since that has been aimed at her.

"Cas, are you feeling alright?"

She has to ask, after all. It'd be nice to just take it at face value, to think that he is actually just glad that she's back and fine, even if back and fine does mean stuck in this town too. It'd be all too easy to just go with his unexpected kindness, but she can't quite do it.

"It's not that I'm not...really glad that you're here," she starts carefully, "It's just that you seem...different." Friendlier? That's it, but she's got more tact than to say that.
