Yuya wrinkles his nose as the smoke elevates, but he doesn't think much further about it--Rita said it's just a change, like what happens in the carnival, so it's probably fine.

At least he knows Strange isn't beating himself up over this stuff, and in response he pulls off the door and stands up straight. "I don't expect her to keep him here forever! But we already have the start of how we could fix it and you keep shooting it down before we even try! If you think you can fix it all by yourself, then where's your solution?"

He can't keep the edge out of his voice completely, but at least he's refraining from snapping at Strange over this. It's just frustrating, when the stakes are as high as Strange's entire life. His happiness.
