Nooot a lot, more like minor facepalm judging. It was very whyyyy could you have no waited ten minutes Oz!! But he can appreciate that Oz is young and probably did it out of a misguided bout of honesty rather than malicious intent.

... Though he is also kind of what the fuck is WRONG with people from this world and not picking up on really obvious things?! Because from Yuri's eyes there was no way Gil's response was normal even for a spaz like him, so the fact that Oz can't see there is something off there is a little frustrating, especially since Yuri recognizes this is probably not the first time this has happened. Of course, he doesn't know that for Oz, Gil has been like that about him his whole life.

So what WOULD happen if they locked us in a closet together?
