I saw that too, but we can't let that influence us much.
First he was acting weird way before that. Didn't want to help out BD, avoided answering, and when pushed gave really vague answers, and most likely slipped. A player has hinted that they also have something on Knight. We need some answers now. We can't let this day go to waste too.
With his flip we have info.
If scum that's great. We know who we're up against without endangering our sheriffs/paladins, and can take a look at the way he interacted with people, who stands out as odd, and which interaction as forced.
If town it's still better than nothing. As I said above a player hinted at having something on Knight, so we look there. Moreover, he hasn't really been helpful at all, and even said he doesn't wanna give us info, so there is that. If he's gonna be inactive his flip is better than that.
Not trying to be rude or anything, I understand real life and problems, but we also need to play the game.
