Xas not responding aggressively allows Hellboy's initial flash of temper to cool over, and he relaxes back into his seat a little.

"I suppose I do," he says, his tone more even but with dubious patience. "What's it to you?"

(Depending on how closely he's looking, Xas might notice that Hellboy's belt has a rosary looped around a couple of its pouches, the cross dangling down near the belt's buckle. If he's capable of sensing such things, the rosary is still entirely blessed, and yet doesn't seem to be causing Hellboy any discomfort.)
