1. It was already a struggle to not use the funniest move in mafia night 0, no way I could hold on to that for more than a night
2. If I didn't use it then I would be the unconfirmed one and then I'd be on the chopping block
3. I expected that if Ratchet was telling the truth about his ability that he'd die anyway. In fact, that's what I still expect. His explanation doesn't seem plausible to me
