I can never remember what I asked for, for any particular fest, because I do read damn near any pairing if it's done well and I do like a wide array of things. This means I'm frequently surprised by what I get, because hell if I know what I asked for. In this case I'm surprised in an I love you kind of way.
There's no way I'm going to mention everything I liked (all of it), but a few things:
1. How you didn't let him be all expository about his why until late, when it was already clear to the reader. 2. How much V loves to fly. 3. Kids that are kids, and that V relates to them without being particularly fond of kids in general. 4. Having James teach him to play soccer. 5. A lot of very sensory description--wet rain and curved bench and smells of beeswax and so on. 6. Hoping Harry resists the urge for a haircut. 7. The way they talk after the sex (Harry's poor knees yay). 8. Neville, helping things along. 9. The Minerva/Hooch that Minerva doesn't confirm because of course she doesn't. 10. Portrait!Snape who still keeps an eye on Lily's grandchildren and knocks other people out of the frame. 11. Bulgaria details that I wouldn't know if they were true but they feel right.
In short: *\o/*
Typo alert of the sort spellchecking never catches, for when you eventually repost: when H pulls away, one-line paragraph: I think that "when" should be a "then." Just sayin.'
