[Katara winces inwardly, knowing how this sounds towards him... and towards her, really, that she's taking him seriously despite his behavior.]

No, he's still flirting. I told him he didn't have to stop - it's not like I like him too. [Sigh.] I told him the only time I'd ask him to do something like that would be if we were dating. I'd rather he find someone else who can like him in return.

[Of course, he responded to that by promising not to date anyone else, but. There you have it.]
