Dude, and I even put a corpse right outside my door!))) Think logically (Silver, you're Mafia, you don't have to think): let's say Lizard is the Confectioner or the Expert and he came to visit me - why describe his death right outside my door?
There are 3 possibilities with Lizard: he's the Expert and came to visit me, he's the Confectioner and was protecting me, or he's Mafia and killed me. If he's the Expert, and I'm Mafia, and I killed him, why wasn't I blocked? We can rule out this option. That leaves the Confectioner and Mafia.
Where do we end up when we save the world?
