"Haha, yeah... How's the rooming going?" Vash pushed his glasses back up a bit, smiling his normal (rather sad) smile, for once feeling too exhausted to his bones to really muster up enough good feeling. Knives was growing, which was --- good. Very good. Meant he wasn't eating wrong or the Hotel wasn't effecting him or something bad that, as a brother, Vash had to be protective over. Because Knives was his responsibility; Rem had said so.
.... Urg. He needed something to drink. Water, not alcohol - things had just happened too fast for his liking, even if he'd always enjoyed a (good) change. Cloud leaving, Mecha-chan's rampage, the curse... it all hit hard at the same time. Originally, he'd thought this place to be a break; but then Wolfwood'd showed up, left, and now Knives was here and he still wasn't sure what Knives this was and....
It was giving him something of a headache. Or would give him a headache, if he could get them. Vash shook his head lightly, backing up a step to give his brother some room, pushing thoughts like that back to get a feel for the situation. Live in the present. It was the best thing to do.
