Inara is starting to care more for Raven's well-being while simultaneously becoming less attracted to him. (And she wasn't even all that attracted to him in the first place.) The more they talk, the more she wants to become a friend and a helper to him, and the less she wants anything from him. Actually, she'd probably be more than happy to sleep with him if he were her client. That's just not... feasible... in Aather. She's a little concerned that he misinterprets her interest (which is intended to be friendly and teasing) as some kind of romantic interest, so she is trying to keep it clear... but at the same time, he's a fun person to play the flirting game with, so there may be some mixed signals going on. But yeah, she likes him! She worries about him, too.

Reverse?
