So it's possible Robz as SK went for slot 3 or slot 8 for conversion, but was beaten to it by ash/ADK. Okay then what does he claim in that situation? He's in a really bad position, 1 SK vs. 8 town. So he goes for something bold and claims first drafting order, hoping for no counterclaim by town (and he thinks he has a good chance at no counterclaim, because ash and ADK both got really good slots, so there's a decent chance one of them got first pick). Then it comes time for massclaim, he wants Axxle to go first to get as much information as possible before he has to claim, but we insist he go before Axxle. He figures slot 1 is a lot better for scum than for town, we know none of the mafia took it and he hopes the last few townies didn't take it either, and claims vig.
I think that's the SK narrative for Robz. It's a crazy bold play and he's lucky he didn't get any counterclaims if that's actually what he did. So just by probability it seems unlikely that Robz is the SK. However, everything that he has done today is exactly what he would have done as vanilla SK, so it's just really tempting to take from that that he is the SK.
Though now I'm realizing that whole scenario I outlined assumes he's not actually the vig, which means there would only be one death tonight (mail-mi), and he has to hope that we take from that that the SK didn't kill. So if we only see one death tonight, it's still possible that that narrative is correct, but not guaranteed since the actual SK may choose to not shoot to make us think Robz is the SK. Whereas if we see two deaths tonight, the narrative must be incorrect and we have to either assume that Robz is town, or that he is actually an SK who had first pick and did not go for a conversion. I guess it's also possible he lied about the first pick but not about slot 1.
Regardless, we're not lynching Robz today, so who are the other options, Andrew, me, joth, mcmc, maybe Axxle? Andrew's play this game has felt a little different to me than in other games. Nothing really sticks out to me about joth or mcmc (which is odd because I usually think mcmc is scummy and then I'm wrong, so maybe worth noting).
