Faolan's not about to explain why he doesn't like her. He knows that it's petty and frankly admitting it aloud would make him feel even worse about it. The truth of the matter is that he has absolutely no right to be this jealous. Lancelot is his friend, and nothing more, with no foreseeable prospect of being anything more, and the thought of it stings deeper than he'd care to admit. So when he catches her smiling at him and him blushing at her, knowing the pair of them have gone out together, knowing that Lancelot sees something that he wants there? Oh, you'd better believe that Faolan is breathing fire, whether she honestly deserves the sentiments or not.

Of course, she doesn't really give him time to refuse the invitation for drinks. It's pretty obvious that he's had quite a few already, but another wouldn't hurt. And it would certainly help him get through whatever conversation was to be had here. "I'm not sure that there's much to get to know," he responds in turn, which he recognizes as the surly comment that it is, but there's no taking it back once it's out. He had meant it to be directed towards himself, at least? Though he's not going to speak up and correct her, however she may be interpreting it.
