Gladio, they just had one of the most strange and impromptu sleepovers he's ever heard of. Granted, he doesn't really have much in the way of experience with sleepovers considering Ignis lives inside the citadel too, but... the prince doesn't seem to mind the lack of professionalism. In fact, he almost seems grateful for it as he peeked out from under the covers briefly.

"I..." Noctis pauses, before gingerly sitting up and attempting to ignore the way his back protests the action. "-forgot the moon cycle, and couldn't sleep."

It was stupid and he knows it; he frowns as he pulls his knees back up to his chest and he hugs them. "But- Dad taught me how not to get attacked when I was younger, in case I ever needed him during a full moon." And since Clarus stayed with the King in his chambers at night, it had been necessary for the young prince to know from an even earlier age than Regis had. Considering his grandmother had slept in another chamber those nights. "Normally I'd just go to the top of one of the towers and stargaze, but..."

He hasn't really had the energy for the trip on his own. Not since he started being able to walk again of his own power.
