Okay I'm back. (I passed, hooray!) I am kind of tempted to kill michaelblume just because I do think he has a good chance to be the demon and also it gives us more opportunities to taunt people. But that's probably a bad idea, and we should kill anthusiasm, because either they're the demon and then we win or because they're not the demon and can protect themselves if they're still alive tomorrow.
(Alicorn's answer leads me to think that the mafia kill is before the demon kill, so that it's a good idea to try to nightkill the demon, like Shoal just said.)
