Also on the subject of reading the setup thoroughly, has everyone noticed that the mimes have a factional JK to use every night? I assume that means the remaining mime can use that on top of whatever other abilities they may or may not possess.
Right, but the mime can't Jk himself, obviously.
I'm assuming that.. but for people like me who want to be able to use the information to try to infer the setup, it makes a big difference that we have a guaranteed JK in the game, because I think it's more likely than not that the reason for the missing NK is that the mime JKd either scum or target. I'd initially thought we could at least rule out the top row in the table, since it has no protecting roles, but even that's still a possibility.
For town PRs who might block or protect against a kill, it might also be pretty important for them to have a more accurate guess as to how likely their own action is to have caused the lack of NK. The full set of alternative possibilities as I see them are:
1) town's babysitter targeted the mafia NK target.
2) town's JK targeted either the killing mafia player or the mafia target.
3) town's weak doctor targeted the mafia NK target (and that target wasn't a vig or miller-mime).
4) the mafia target was town's 1-shot deathproof.
5) the mafia target was the remaining mime, and they were 1-shot bullet-proof.
6) scum forgot to submit a night action.
