The way Moe worded seemed to heavily imply cop, and that's priority for mafia. From the setup so far, I'm starting to think we don't have a cop (otherwise they'd should've claimed results + a miller would've likely claimed, plus we already had a secondary investigative role), so I'm assuming the remaining (possibly two) mafia doesn't have godfather, making a potential cop insanely dangerous for mafia.
Minish clearly noticed the soft, as well as me (I even pointed out the change of heart). I don't remember seeing any soft hinting at people being mechanically cleared coming from other players, so I'd be surprised if they went for a alternative target for any reason.
I'm not sure if I follow your logic about another PR not dying not being clearing.
