There's a nod, as if Knives had figured on something similar already. The information about no plants being around is a bit more of a surprise, he hadn't reached out and knew better than to try. While they were inevitably incredibly forgiving and would respond if he asked them to, it no longer felt as if he deserved it. Not after what he put them through.

"Knives.. is probably better. I haven't been 'Nai' since I was half your age." Or younger. The fact that Vash IS so young is really all he needs to know there's some kind of time shenanigans going on. It made him feel tired. .. More tired. "My home used to be right over there. I can't tell if I've moved forward or backwards, but given you.. I suspect backwards."

And of course, the missing home. And tree. His tree! It had taken so much coaxing to establish itself and properly grow! He begins his westward path again; with nowhere else for Vash to go he'll likely head the same way. "Depending on the timeframe, there may also be people there who are ... very hostile. If they are, scream and carry on and pretend I'd forced you to come with me, they'll focus on me, and you can leave town." His tone doesn't waver, as if this is normal and expected, just another bullshit part of dealing with humanity. "You look different enough from the posters that they'll likely decide you're someone else."
