[Kuzuryuu is polite enough not to call Leon out on the fact that he obviously had no idea that this is the right way. However, he is not so polite that he doesn't roll his eye once the other boy has turned his back.]

[He doesn't offer so much as a glance at his tiny, still near-tears doppleganger as he trudges up the stairs after Leon. But there's still one last tiny and feeble "You murdered them," all the same. But that's the last one it manages to get in, of course. Because he can't follow them up the stairs and back into the hospital.]

[It's only when they're both safely upstairs that Kuzuryuu finally looks back. Just at the doorway leading to the stairs to make sure there's nothing there.]

Finally. Fucking glad that's over with and we can get on with our lives. Watch your step from now on so you don't get stuck down there again. I dunno if it was the same for you but I fell through a trap door...
