It's autumn, and the first day of September means the Hogwarts Express.
We find Harry, Ginny, and their children, Lily, James, and Albus, at Platform Nine and Three-Quarters, getting reading to head off to school. Lily is too young to go, but James is already in school, and Albus is about to head off for his first year.
James taunts him about being in Slytherin, and the younger boy gets all riled up. He's also very nervous.
By the last carriage, the family finds who they're looking for – Ron, Hermione, and their kids, Hugo and Rose. Rose is also about to embark on her first trip to Hogwarts.
Ron jokingly tells Rose and Albus that they'll be disinherited if they don't end up in Gryffindor.
Everyone's distracted for a moment by Draco Malfoy, who's seeing his son, Scorpius, off to school too.
Ron makes a snide comment to Rose about not getting too close to little Scorpius – he doesn't want a pureblood in the family. He's joking… kind of.
James reappears from the train with big news – Teddy Lupin, Remus and Tonks's son, has been spotted making out with Victoire, one of Bill and Fleur's daughters.
James is all in a tizzy.
It's time to go; the school-age kids are all bundled on the train, and Ginny reminds James to give their love to Neville, who's the professor of Herbology now.
Harry has one last word with little Albus, telling him that it doesn't matter which house he's Sorted into.
He reminds Albus Severus that he's named after two great Headmasters of Hogwarts, one of whom was a Slytherin – and one of the bravest men Harry ever knew.
Harry tells Albus again that they don't care which house he's in, but if he cares so much, he can tell the Sorting Hat, and it will listen to him – as it did for Harry, all those years ago.
The train pulls away, and Harry feels a little bittersweet tug at his heartstrings. Ginny reassures him that Albus will be all right.
Harry, touching his scar, knows that he will be. The scar hasn't hurt since the battle of Hogwarts, and all is well in the wizarding world.
