JTF has an inspect of some sort, so I'm going to use it on him. He'll likely have useful information, regardless of any potential demonification on his part.
Is there any way or role that would get a hint as to whether the revived JTF is still town or a demonic SK? Other than priests, what other roles interact with the dead? How do you think the vampires work?
It's possible, but I don't know how likely it would be for this game. Using knowledge of how the roles work from previous Supernaturals, a Dreamwalker could possibly get a PM directed towards JTF, and he would be able to tell whether it was a normal or demonic resurrection. There are other possibilities that I'm probably not aware of. So, it could happen. But it also could not. I wouldn't know.
And there are plenty of roles that interact with the dead. The Sexton knows whether the dead have been disturbed, and the Warlock can communicate with the dead in some fashion. There are probably more.
And the vampires could work like a regular scum team, or they could be a cult. The flavor for the JTF kill doesn't match what I'd expect a vampire to do, so it either means the vampires were blocked both nights, which I think is unlikely, or the vampires are conversion-based instead of kill-based. If it's the first, then we're lucky. But I'd expect this amazing vampire blocker to have claimed by now, so the vampires probably don't work like a normal scum team. So it's probably conversion-based, although it's anyone's guess as to how the conversions work, which would factor significantly into how much of a threat the vampires are.
In either case, it looks like there's a third party killing role about. Hopefully he'll shoot some vampires at some point.
And the flavor not matching up to a vampire's work is just WIFOM.
Flavor's important to all Meph games. The first Supernatural had werewolves, and I think Org was a demon or a devil of some sort, and ToonyMan was a Vampire Hunter. In all three cases, the flavor was distinct for each of their kills.
If it doesn't look like a vampire did it, a vampire probably didn't do it.
