I get to PM Bananas a name of a person in the game. That person gets an extra boost and gets to use his or her role twice in the same night. I gave it to Lostfap. If you see in the write up, Rush was shot through the head and then the bullet went through his skull and the same bullet hit Walla. To me, at least, Fap has a role that involves killing someone (SK, Vig, one-shot kills, andGF are all possibilities)
So in his post when it said "mystery man" I'm assumin that that's me.
That's because the hider was behind someone who was shot. That's the hider's role. Read it.
