Is it okay for Elliot to take notice of the death energy around your character if they have it for reasons like being a vampire or undead or ill, or for whatever other purpose they may have it? (If it's not, I'll just play that he'll ignore it. And just because he does notice it doesn't mean he'll out them at all, he's a witch that's likely to try to eat your dead grandma, he's not gonna be airing out people's laundry. ):

Pretty much everything Ash said regarding Vanessa above about her blood, also applies to Scarlett. Basically an Anti-Vampire?!

Here's the difference in terms of Death Energy. Scarlett hasn't died so much as she was bitten by a vampire, should have died in her world as a result but, Vanessa biting her (earlier in canon) activated her immunity to Vampirism, making her this, super powered, possibly immortal, anti-vampire.

Confused? If it helps, me too and I have context. Basically if I had to guess, there would be a faint death energy around Scarlett that Elliot would be able to see. Enough to make him take note but not enough for him to understand clearly what has happened to her?!

Would you be interested in pursuing CR with Elliot trying to whip up some kind of feeding arrangement? (i.e. blood for death.): Scarlett would very aggressively protest that she's "Not a fucking vampire". Its believed she's just like Vanessa, but whereas her sister will feed off somebody in a jam, Scarlett hasn't been pushed that far. Yet.
