He wakes up largely because it suddenly feels several degrees colder in the bed, and the reason for that is obvious as soon as he opens up his eyes and rolls over, finding that Ned is no longer in the bed. There's a second where he wonders whether Ned has just left entirely, but then he hears the shower running, and relaxes back into the mattress slightly. Ned hasn't left. Ned hasn't decided he's sick of him -- so far, at least.

Throughout the night, he knows, he'd been very cuddly, and there's another moment where he worries that perhaps he'd been too cuddly, but Ned would have shoved him aside if he had been, wouldn't he? Finally, he stops lolling around on the bed and sits up, which is when he notices the note on the bedside table. It puts another huge smile on his face, although there's no one to see it.

Fumbling under the bed, he comes up with his underwear and undershirt, and tosses them on, then heads towards the kitchen with the intention of making coffee for the both of them. That's the right thing to do, isn't it? Were he feeling more bold, he might surprise Ned in the shower, but he still feels somewhat shy, so coffee it is.
