"Bill? What?" Ron almost said who, but of course that was a stupid thing to say. He remembered Bill. Sort of. He was a little older than Ginny when he saw him last, but not by too much. Not enough to have good, solid memories. "What's... how? He's old... Merlin, he has to be much older by now... and uh... whose bed is this, anyway?" Not that Ron cared, really, but he was kind of hoping it wasn't supposed to be his.
He saw that Ginny was getting upset, though, and forced himself to sound annoyed. "Gin, bloody hell, don't get all worked up. You look like mum when you do that. I'm fine. I'll just slap some sheets on this and it'll patch up. It looks worse than it is." Not really, as it hurt like a fucking son of an Umbridge, but joking about it helped a little.
