In Downtown, usually in the area around the Tremere Chantry, the Drughouse and Hallowbrooke Hotel, there's an NPC that looks like a palette swap of the male Toreador Model, when as a Nosferatu, the "Possible Masquerade Violation Sad Mask" marker doesnt appear. same goes for another NPC that loiters around the Hallowbrooke Hotel entrance, but I think that that's one of the old blood dolls in an older version of CE. He still has the talk icon for him, but pushing it causes him to both turn towards you and try to walk away.
