If Didds is SK we need to lynch her right now or we lose, which essencially puts us in the No Lynch scenario, and if she's not SK then we basically lose.
Can we even win if she's SK?
D5: Dax lynch -> Dax doesn't die but Ezri replaces Jadzia. (3T,2Maq,1SK)
N5: Ezri takes out one town player, other Maquis shoots town. (2T,1Maq,1SK) OR (1T,2Maq,1SK)
D6: We re-lynch Dax, since it's the only way to kill her. (2T,1Maq) OR (1T,2Maq)
N6: In the 2T case, it's down to slim chances with PRs in N6&D7, in the 1T case, it's a pretty unavoidable Maquis win.
Okay, so it boils down to more or less the same reliance on town's PR spread as my "let's kill the SK". Given that I was initially pro-SK-kill and then became persuaded that perhaps a Maquis kill is okay, let's check what happens if Didds is Maquis and we lynch her:
D5: Dax lynch -> Dax doesn't die but Ezri replaces Jadzia. (3T,2Maq,1SK)
N5: Maquis probably kill town; SK may kill either. (2T,1Maq,1SK) OR (1T,2Maq,1SK) OR (2T,2Maq,1SK) -- if kills overlap or SK is targeted by Maq.
D6 in (2T,1Maq,1SK): if we can lynch the SK, then it just depends on the town PRs. If not, SK may win.
D6 in (1T,2Maq,1SK): I think there's no way for town to win this.
D6 in (2T,2Maq,1SK): This is the same as what happens in the mislynch case, and is not great for town.
The other possibility that nobody's mentioned is that if Dax is Maquis, she could have swapped claims with her remaining buddy, as a deterrent. I think it's highly unlikely, because if we lynch someone and they fail to die, we know immediately that they and Didds are the Maquis. But I'm not sure it's a gamble no scums would ever take, so it's worth mentioning, at least to be sure we've examined all the options.
Lastly, I haven't forgotten that the e wagon of D1 has WCD as the only unflipped person on it
and I'd used that as factor in scumreading e at the time he was lynched, it's just everyone else has moderately-scummy-looking things too (like Ash's hammers or raerae being off-wagon on unpopular votes way more than average), so it
could just be a once-in-a-game sort of coincidence.
