Leif wouldn't be the first person to be confused by Hugh's scent. Students with a heightened sense of smell were endlessly curious to identify it. Hugh was forbidden to tell them, and usually made something up. Most of the time it was amusing for him, but sometimes there would be one student more stubborn than most, and he had to go to lengths to shake their curiosity off.
The knock-knock joke detail made him chuckle again, a sound that more of a rumble in his chest than actual mirth. "I was torn between moving on to those or bad puns. It's probably a good thing we didn't get that far." He knew far too many bad puns.
Speaking the old language was refreshing, actually. The directness with which they got to the topic Hugh wanted to speak on wasn't. He couldn't be sure how this information would be received by the northman. Ah well. Right to it, then.
Hugh's lips twitched a bit as he snorted. "That is a complicated answer," he said then took a breath. "I was hatched in Asgard." He waited to see which reaction came first: disbelief, outrage or something more surprising.
