OK. Before I say anything, I promised my role, and my role I shall give. I was given the simple role of Doctor. Since Crabbe said I was insane yesterday, I must be an Insane Doctor. I didn't want to say anything about it because if Crabbe was mafia I would be waiving a flag saying "Look Mafia, here is your doctor waiting to be shot"
Who did I protect? Night 1 I protected myself, because I feel that a doctor becomes more valuable after each day. Luckily I didn't kill myself.
Night 2 I chose to protect Nobody, because I knew I was insane and didn't want to risk killing anybody. I aslo have decided to not protect anybody else from now on, because I don't want to risk killing the power roles accidently.
So Sirius was mafia, and I trusted him with his plausible roleclaim. I'm a bit shocked, but that has passed, because only scum kills my little sister!
