Okay so just thinking out loud here. And I'm only saying this cos it seems Mob don't have a heal ability.
So I'm thinking there's only 2 reasons arby would say something like that:
1. He was played by Mob cop
2. He's Mafia kamikaze guy and mob are making g a push to take down an additional person now, given we lynch arby tomorrow (arby lied, hence mob, if #1 isn't true).
Having said that, we have a move we can make.
" . IF after DAY 3 both Q and 007 are still alive Q gives 007 a one time use KILL that is only usable during NIGHT phase."
Imo, 007 needs to take out arby tonight so that he won't be able to take out someone with him during the lynch.
If arby is town and was just being played (imo, not likely given its arby) then he needs to reveal who contacted him, so we can lynch them tomorrow. This can still go ahead after 007s kill.
Again, just thinking out loud! Not part of any town group atm, but hopefully it helps!
