Ron's expression brightened loads. Hermione had kissed him, for Merlin's sake! He had been kissed by Hermione Granger and he was going to die. Well, okay. Maybe not now, because Ron wasn't exactly willing to die when there was a chance be might be able to snog Hermione a bit more later on down the road here (or sooner), but it felt like he was going to die. In a good way. Cheeks flared up, Ron grinned off at Hermione and said, "Not really, no. I think I've got the message." That being said, he reached out, hauled her toward him, and pressed his mouth against hers with much enthusiasm.
Grin still fully intact, Ron yanked his head back and said, "You, Hermione, are the most brilliant person ever and I'm wicked sorry that I made you wait for so long."
