Ron's voice is great here, and the first person is very effective.
I mean, we did, but not like the kind that gets so pissed that they wake up in a puddle in a Knockturn Alley ditch at seven in the morning with their hair in pink and blue streaks, wondering why they're wearing a dragonhide kilt and mismatched boots. Well, at least Harry and Hermione never have been. -- Bwaha, that line sold me on the fic. :P
You've done a fantastic job of portraying the level of comfort that these three have with each other. This is absolutely the way canon should have ended. Hot and sweet.
