Fern is fascinated as he listens, nodding along. Those are all things (except whatever robot Hitler is) that he's familiar with, which is... nice, really. Most of the people here aren't from worlds like Ooo, he's learned that much, but this guy? This guy's home has to be similar.

... If not actually Ooo.

Now that would be surprising. It's been months, and any hope he had of seeing someone from home show up had started to die.

"Fern," he replies, reaching over to shake Hellboy's hand. "You aren't from Ooo, are you?"

With his luck the answer is probably no, but he might as well ask.
