Given the world they literally live in, vampire ghost was literally possible. Come on, Tony. Don't be silly. They'd both seen worse things back home, whether it was the same home or not. Though of course you couldn't be a zombie vampire ghost. That was just ridiculous.

"Dude, Mojo kidnaps people from Earth too. Don't pretend that's weird. And ghosts are real. That isn't a question either. Hell, vampires are real. My brother has literally teamed up with Blade. Soooooo, still waiting for proof it's not vampire ghosts. As for things moving, it moved faster than I could perceive, Tony. Not even a flicker of it starting to fade, no light sparkles, nothing. That's fucking strange."
