He'd probably have a similar aura, I'd imagine, if only because he's the vampire analog from his world, so he'd likely read along the same lines as a Blood Breed. Maybe slightly less murderous, if that's a thing lol.

Pepper would be open to having her vision hijacked, if she knew it were an option. She'd find it pretty cool, probably. Devin... would likely not be so willing, unless it were critically or tactically useful. As long as he gets asked, it'd turn out okay.
