This takes place right after the end of the Seventh book/movie. Albus and James are the children of Harry and Ginny, Scorpius is Malfoy's son, and Rose and Hugo are the kids of Ron and Hermione. James and Scorpius are in their third year, and Rose and Albus are first years. Enjoy (:
Albus had finally boarded the train, and met up in a stall with his elder brother, James. "So, I guess this is it?"
"Of course not, Albus. We'll be returning home for holiday, and maybe Mum or Dad will pay a visit to train the Quidditch team or something!" James reassured. The train took off, and they saw the last of their two parents, Harry and Ginny Potter, and their younger sister, Lily, waving them goodbye. In climbed a red-headed girl, who was beginning her first year of Hogwarts, just like Albus.
"Well hello, guys. Mind if I join you in here?" She asked.
"Well sure, Rose." Replied James.
Rose Weasely was a little petite for her age. She was James and Albus' cousin. "Mother told me that the classes are fairly easy. She has even allowed me to have a jumpstart in charms! Watch this. Wingardium Leviosa!" At that moment, the book she had been carrying began levitating.
"That's simple. This year I get to learn Divination, though Dad was reluctant towards it. He told me not to listen to the predictions of Professor Trelawney… But I think she's brilliant, really." James bragged. He was about to begin his third year at Hogwarts. "And I really hope to earn the Quidditch Cup this year. Gryffindor hasn't won since Dad was seeker." He went on.
"Well maybe this year may be lucky for you. Dad hasn't been training you all summer for nothing, has he? Maybe even I can make the team this year…" Albus imagined himself soaring on a Firebolt1000 across the hoops, making the Quidditch team as the new Keeper… "James, do you recall any teams with an open Keeper position?"
"Actually, Gryffindor's just graduated, which means they need a new captain too! And I believe Hufflepuff, but I doubt anyone would want to represent them…"
"For your information, many noble witches and wizards have come from Hufflepuff. I would be honored to be put in any house." interrupted Rose. "Look at Cedric Diggory, for example! Excellent seeker. Too bad he was killed that one year… I read all about it. Voldemort had killed him, you know."
"I think we'd know that… Father has told the story at least twice. He was there, Rose." James butted in.
"I suppose…" Rose changed the subject. "Have you heard? Mr. Longbottom is going to be our new Defense Against The Dark Arts teacher. I've heard he's very nice."
Just then, a blonde, tall third year boy popped into the doorway. "Mr. Longbottom? That git. My father told me he was a great coward until his seventh year."
"No one asked you, Scorpius. You wish you were as brave as him." Rose said.
"And so what if I did?" He kidded, while taking a seat next to James. Scorpius was placed in the Slytherin house. He and James had known each other since their first year, and while they were great friends they also were very competitive about who would be the most successful.
The four children sat and talked about their favorite Quidditch teams and wizards and became so preoccupied that they were surprised when the moving train came to a halt.
"we're here!" Squealed Rose as they all climbed out of their stall and carried their luggage with them into the hall of the train, James making he was extra careful with his new Nimbus 4000, which was given to him by his father for making the Gryffindor team as Seeker. They all shuffled out of the Hogwarts Express.
"First years over here!" Shouted a fifth-year Gryffindor prefect.
Albus turned to James. "Well here I go… Wish me luck, brother."
"I'll see you at the Gryffindor table, Albus. And don't be worried, you're going to be put in the right house anyway."
So Albus and Rose joined the crowd of about 20 first years as James and Scorpius set off for the horseless carriages that transport them to the school grounds.
