If you are the doctor, and not counterclaimed, then I have to trust that, Largehorn. At least as far as this game has a doctor. I do not believe in a JOAT and a Doctor in addition to myself. That's too many power roles in one 8 player game called "the basics". A JOAT with an investigation in addition to a cop is unlikely. A JOAT in addition to a doc is unlikely.
My best guess is that the mafia did that kill, to "keep it fair", in some idea that what Graeham did was not actually right on some higher level. Though, the alternative is that I was the actual night-kill, and that this kill failed due to good doctoring. Only the mafia would know that. And possibly the doctor.
I also have a very hard time thinking Listo is scum. D1 he had to choose between myself and Graeham, and he picked Graeham. And D2 he kept at it before I dropped my result. I have far more town vibes from Listo than I have from Virothe. And I'm saying that as someone who have a result on Virothe.
My alternative is Crackleslap. But Graeham tried to get Crackle lynched. So that doesn't really make sense either.
