Okay, I think I messed up. I am the vigilante and I messaged BHB last night, not knowing the med kit is in the game. I deleted the message before he saw it, but forgot to block him from it first, so he still would have gotten it. I'm leaning towards him being mafia because he hasn't messaged me, despite undoubtedly seeing it.
So yeah, my bad, TP. If the real doc could save me, that would be great. If not,
