Ron hadn't realised he was holding his breath, but as Hermione accepted his offer, he let it out long and slow. He raised a hand to toy with the quill again, then thought better of it and stood up straight. At her comment, he grinned. "Course I can still beat you. You haven't even seen my best moves yet."
Now he thought about it, she probably hadn't even seen the chess set he'd gotten for Christmas last year. This was sad, both because it had particularly spectacular battles, and because it showed just how long it had been since they'd done anything of this sort. Once they had done it every few weeks, but that was before.
He waited while she got her things together, and then they walked to the lifts together. "I can pop out and pick up the food, if you like," Ron said, holding the lift door till she'd stepped inside, then he followed. "Mum sent home some things with us Sunday, so there's plenty to drink. Butterbeer, wine, juice and probably some other things I've forgotten. Wouldn't suggest stopping by home first. You never know what those two might be up to."
He pulled a face, then gave a little chuckle to show he was joking. Mostly.
