Not sure, probably just mood of Vallo. I've been in two places now that it could go either way, but no one fessed up on it, so.
FTR For the record, there's undead here that don't eat people, and some that eat brains too but like, sustainably sourced brains (aka already dead people or ... idk, tofu brains) but it's fine, it's a big shrug as far as I'm concerned. I drowned in a frozen lake, and when I was alive again after shit is just a little fucked up. Not quite fully ~alive~ is what I assume. Don't talk shit about me in your vallo binder archives or whatever, dude.
