Nyx flashes the little creature a smile and a nod, keeping a couple fingers on his jacket just in case it slides out of his lap. But he's content to let Noctis doze, even once they get back to the apartments and he's able to set his prince down on the couch. It's not until he's obtained stew and tea that he returns to the couch, gently lifting Noctis back into his lap and running his fingers through dark hair. It's less an attempt to rouse him as it is affection that, if it does, would be just fine.

He's not about to leave the younger man until he has some answers, though, so if that means being napped on for w bit Nyx isn't about to argue.
