Better then not bringing up any of the possibilities of it and it end up being a mafia trick. Though I do agree we need to find him a target to kill before the end of the day. If it's a mafia killed then he's probably a vig. If it's anything else he's probably an assassin or a vig.
As for targets Sub-Zero seems popular but I can't really say there's too much justification for him yet. He hasn't really done anything that screams scum. Sonic is a target I could see us going after though as for reasons I already have stated.
