Well. That's a good deal politer than what he was expecting - certainly a lot politer than he's merited in the past - and as such it makes him pause, mildly suspicious. The slur is what makes his mind up for him; even if Sparhawk is up to something, and this seems a little underhanded for his side of their grappling, he's dead certain he can knock him down if he's drunk.

He'd rather not have to, but the thought occurs to him and plays a part in the curt nod he gives. "Very well. Been drinking have we, brother?"
