Of course it does. "Different-- but--" Vash tries to complain about being separated so soon after meeting, but then he clamps his mouth shut, looking away. It's Knives' privilege, to want to be rid of him. To not want to be saddled with someone as clueless about this world as he is, or with... whatever happened to get him from how Vash knows him to... this. After a moment, he faces him again with a grin. "And don't be so sure I'm not fast enough, I've had a lot of practice!" Specifically with dodging bullets. He's very good at it!

He considers the rest of the information, and the implications. His mouth turns down at the corners again.

"People got hurt again, didn't they." Quietly. And yes, he knows that would not be Knives' priority, or even something he was bothered with, but it matters to him. One more faction to keep from hurting the others. While staying out of their reach? Something like that. "I'll keep an eye out, thanks, Knives."
