Iruka gets a muffled groan in relief as a response. Followed by attempted snuffling, but his nose is too stopped up and he'd rather not get mucus everywhere.

The first thing he notes is relative silence. No padding of extra feet, no surrounding voices...

He's tired. Yet still, he makes at least one attempt to stand and find his own way to the bed. If he can't make it, he knows Iruka will carry him there.
