[Naturally, Kanaya doesn't know how familiar this girl is with their whole... story. If she only knew Tavros, then there's a lot she would have missed.]

We all lived through the destruction of our world, and through significant events thereafter. We.. weren't safe for a long time though. By the time it was all over, there were maybe five of us left.

[True... of those five two of them died before and remember it, and all of them died more than a few times in different timelines that they don't actually recall. And there's another two or three trolls that Kanaya's not even sure about the fate of. But hey, things are confusing enough in this conversation without getting into all of that just yet.]
