the best I can do without directly posting spoilers for the game.
I've yet to finish the game, I didn't know about those NPCs
Hmmm... I wrote something about endings... and then I thought it was a spoiler... ehhh... anyway... I just wanted to say that this is kinda "crooked" wiki and because of that people there often do not find the answers to even ordinary questions and if you haven't completed the game what's the point of posting this link about which you yourself don't really know anything since you still haven't completed the game?=)
