[Vash sighs. That name again. Knives had enough to take in at the moment then trying to explain alternate realities right now. Even not having any face to put with the name it's not hard to figure out that whoever this was they were important to Knives.]

I'm not sure that's something I should answer. [Even if he knew the answer.] Sometimes, it's best not to know how the future will go. [There's a brief pause. Well, he should probably be told sometime. Vash takes a breath and decides to give explaining alternate realities a try.] There have been times of people from alternate realities from each other showing up here too. People who know each other, but something in their past was slightly different the caused them to remember things differently or have different futures.

It's-- kind of hard to explain, but just because something happened in my past it could be different to your future. I wouldn't want to accidentally tell you something that wouldn't be true. [On purpose, well, he's never been very good about lying anyway. Truth he had found usually works a bit better. More so when the truth is something people don't tend to believe anyway.]
