Dawg, if this really was the gunslinger game.. you would be right and I'd tell the GS to just shoot me and be done with it to prove JB is lying. Then I'd be the gunslinger and JB would get killed.
However, I still see no evidence from Pappy to suggest this format will continue AFTER nightfall. That theory goes against everything we already know about THIS game.
If that's true it means I won't get that gun to take JB out like we did in that game. Pappy's time machine will kick in before then, we'll have lost the innocent shooter (who the mafia picked themselves for that reason in the first place), and they've got another 48 day and another screwy format to use to try to confuse us again with something else.
Meanwhile, they've succeeded in protecting Ogre long enough for us to go after other people instead. You know as well as I do that delaying an inevitable lynch is often all it takes to divert suspicion away from someone long enough for new suspects and new diversions to mislead the town into thinking someone else is "more scummy." It's a known tactic to stay alive long enough to do something else you already have planned.
