Ron's face started to blush bright and he fumbled again for his words even as he danced with her, his arms about her.
"Hermione! What else do you think I want to do with you? Us alone? Doing....?" and there was some dawning and his face went brighter by about three shades of red. He was so embarrassed by the notion that she thought..that he thought about her, doing that with her."
He looked down in her face, and he was frowning as he thought about that idea and he didn't know what to say. After a few moments, he swallowed at last and spoke.
"I only thought about being with you somewhere a bit quieter. The common room is wicked crowded, but we tend to lounge there anyhow. I expect it won't be much different. Harry and I have been trying to figure a way to get you upstairs with us for years, so we could all three study and scheme about things in peace," and he moved with her more as the music changed slightly, "I mean, don't you trust me? I hardly think we are ready to do anything that needs us to be alone..likethat," he said, knowing he sounded a bit prime as he said it. He was a git, he knew it, but he had only thought about lounging with her, her head in his lap or his head in hers as they studied together, with maybe a snog snuck in every once in a while. It was just something he didn't think he could do in front of all of his other mates. But maybe he could, he realized as he held her, a hand moving up to stroke a stray curl.
