“You did bring it up.” He doesn't even bother trying to conceal the quiet laugh at Hiei's response. The fox was behaving until the fire apparition said it out loud, after all.

Kurama would not have expected this, himself, if he wasn't seeing it with his own eyes. Of course, he'd been working towards it all along, but there was no real way to know in advance how far he'd get with the younger demon's prickly nature and preference for demon world.

The nip earns him an amused hum, pausing when Hiei's reasoning is revealed before grinning softly. “I suppose I will simply have to be quiet then. Although... You do know I'll be joining you, right?”

While he didn't expect Hiei to know most human customs without explanation, Kurama isn't sure if he really needs to point out that he'll be coming back to bed once breakfast is made.
