Hi. Well, I think the chance that both WW and Space are town is quite low, given my survival.
From my point of view, the two questions are somewhat independent, so conditioning the likelihood on your survival is pretty much irrelevant.
If WW is a vig, he was almost certainly a lucky block by scum, because town has a rather low likelihood of having a RB, whereas scum is guaranteed one (since we know we have at least two non-T rolls in the setup).
If WW is not a vig, he's pretty much guaranteed to be scum. I guess him being scum makes scum slightly more likely overall to do clever things, since he's an experienced player, but that's about the only way the vig thing and the faust-not-being-dead thing should be correlated, I think.
The question of why you're not dead revolves around what the town doctor(s) or possible RB were up to, and on whether the scum made some form of mistake (like not getting their kill together on time, as WW suggested).
Argh.. lots of PPEs to go back to. Sorry!
