I'm going to assume infinite-vig, because as others have noted 1-shot vig was unlikely to shoot last night.
Assuming that's true we have MDDVV?T. So, there's a vig, doctor, and other PR out there.
I was going to say the vig was an IC, because he can shoot counter-claims, but then I remembered that there's a roleblocker. So, that actually doesn't work in this case. Vig should probably NOT claim today, because we want him to shoot to restore parity, and a roleblocker can keep that from happening.
I don't see value in speculating about who killed whom. All it does is help scum narrow down who the vig is. They know who they killed, they know who the vig killed. Let's stop noting how surprised we are that one or the other died, because that just tells scum who the likeliest vigs are (accepting town lying for WIFOM, which is always dangerous).
Okay, well, stuff happened yesterday. As noted, there was an ash wagon that can be looked into (either side of it, staying off or getting on). I don't see where the view that non-commital stances are scummy comes from. Scum knew ash was town, and they could very well have argued that point with confidence. The question really shouldn't be what stance was taken, but how it was taken.
The sudgy wagon is potentially pretty useful to analyze. Scum thought he would flip town, while town very well might have thought he would flip scum. There might be some discrepancies to pick up on there. I think I'll start out looking there tomorrow.
