Sanzo does indeed give him a look, not pausing his rapid-fire chant. Not to tell Devero off, and not to argue, either. He's pretty easy to shoulder around, he doesn't weigh any more than his father; might even weigh less.

Look, he's been in enough shitty situations -- this is a Tuesday, after all. It would be counter productive to interrupt what he's doing to throw a fit.

So even though it doesn't do the focus he's building any favors, he drops one hand from the prayer pose and flicks the gun out of his sleeve with a snap of his wrist, and shoves it at Devero. Don't blow your own ass up, big guy.
