Mark looked up at the newcomer that walked past. Something familiar about that one, as if he should recognize him from somewhere. Something.. dark, too.
But maybe it was the whitelighter part of him that sensed it. After all, his superiors above had told him quite a bit about demons, darklighters, and warlocks. Mark waved slightly, then spoke in his English accent (it came with his current form), "Ohh... hello there."
