Well... I am genuinely confused... I'm not too sure what to do right now... Filch would be the next one to prove or disprove Snape's innocence... I'm seriously doubting that Filch is the Paranoid Gun Owner... since Snape's role would 'randomly target' someone to investigate. It is still a targeting role, so he would have died. I truly am at a loss... but I say that it would be easiest for Filch... he doesn't seem to have been targeted by the Mafia or we would have more Mafia deaths. And if it is true that he is the Paranoid Gun Owner, the Mafia is not going to target him now, because they would kill off their own person...
