Men. Toothless runs this word through his mind, remembering what Castiel had said about vikings being called 'humans'. He defaults to viking, as this is the only kind of... human... he's known. The Nightfury, confused, cocks his head to the side when she mentions spawning. Do vikings spawn? He's never seen any of them spawn.

Of course, he's never seen any of them lay eggs, either. Very strange.

Toothless trills, higher than his previous sounds, and then settles down to lay on his stomach by Panne. Their surroundings get a bit chillier than he'd imagined, and the warmth of the fire is very nice on his black scales.
