Night Watch. But I don't know much more than anyone else, since Stephen was inactive. I never got to get any private info directly from him, I just knew his identity.
Except if the vampires are killing each other - and I said almost assuredly because that's possible but doesn't seem like the most likely conclusion - then we still know that the vampires aren't the scum faction because that inherently proves that the vampires aren't working together.
No, but there is evidence against the vampires being the scum faction. You, on the other hand, have been demonstrating general scummy behaviour.
No it's not. Stephen having a lynch is, but again, there is evidence of vampires being the victims of the scum faction, which is not the case for the Hippos. All of which is irrelevant to your case in particular, because your scumminess is gameplay related, not lore- or faction-related.
