Stupid Banner influence. He can ignore it when he's blitzed on rage, which he isn't currently, and so the bleedover from Banner is stronger and more likely to loosen even his agitation. It's so not fair; can't Banner ever let him have something? Like smashing Fang Lady if he wants to? Not that he really would kill her, even without Banner telling him not to. Shake her up a little (literally) and then leave her, sure.

"How do you know Banner?" he snaps, pressing ahead. He doesn't know who Pendragon is and he doesn't care. All that matters is why she's important enough to Banner that the recognition reaches through.
