So here are the 5 possibilities from my perspective. I do not include my thoughts on what anyone should do because I'm not sure:
A. JK/not JK claim stalls. We have no new info other than that a couple of particular people are not JK. But still a chance there is a mystery JK who can protect me! In terms of a lynch for today, we probably should try to get Grujah to talk more and get a better sense of whether he's lying the old fashioned way. Or perhaps we move on to other targets to be safe since there is more scum out there for the lynchin'.
B. JK claims and everyone believes him. We are unsure whether Grujah is lying (I know myself to be not lying). So again, we either try to deduce if he's lying or lynch someone else. But we've outed another PR, and WIFOM all around for the NK tonight.
C. JK claims but might be lying. This seems more likely than B. After all, not believing Grujah's doctor claim is what got us to this debacle in the first place. If Grujah is scum, a scumbuddy has incentive to fake claim JK to avoid scenario D.
D. Everyone claims not JK. Easy. Lynch Grujah. No other protective roles, though, so I die tonight.
E. Multiple people claim JK. Ugh.
