"Whoa, so... new twin?" Nathan asks, spotting the little Vanya-lookalike and falling in step beside him, because what the hell, why not? He looks just like Klaus, only more handsome and younger, so the thought of some little dude looking just like Vanya isn't really all that surprising.

"Are you one of them?" he asks. "Another Hargreeves? Ooohh, alternate universe Hargreeves? That's gotta be a thing, yeah? Somewhere out there you've got these other siblings."

He pats down his pockets for a joint and his lighter, then shoves it into the corner of his mouth, looking at the dude expectantly.
