( Yuri tips his head back to look toward Luke, having caught the snickering to start with. He's frowning by reflex; there's a part of him that's always ready and bristling when he thinks someone's being dismissive of him in some capacity that might matter. )

I doubt that. ( he leaves the "asshole" implied. less because of any will he has toward Luke and more because this is exactly his offhand, prickly attitude. ) It's a "fight" between two actors. If you can't manage to coordinate two people on a contained stage, you've got other problems going on.
