This is a flashback from Rose's POV. This is set in their 3rd year... (BTW, they're in their 5th year at the current point in the story) It might come from Scorpius's POV later on, but this explains their feud.
The sun was shining. The sky was a bright and shining blue. There wasn't a cloud to ruin this perfect day. Or so I thought. It's so wrong that such a beautiful day was the day everything went wrong. I knew that Scoprius and Albus had feuded since their first year at Hogwarts. It had started with silly pranks, but as they grew, it had become more and more serious. They absolutely loathed one another. Albus had just recently earned Scorpius a month of detention from Professor McGonagall after framing him for the theft of the sorting hat, a feat he had performed himself, and Scorpius had yet to get his revenge.
Albus was on his broomstick. He had been trying out the new Firebolt 101 he had just gotten for his birthday. I had been sitting with Teddy in the green grass, watching Al show off in the beautiful sky. He was laughing like crazy and having more fun than I'd seen him have in months.
I blame myself. I should have seen the blonde lanky figure dragging his broomstick across the yard. Me and Teddy saw him as soon as he took off, but by then it was too late. I watched helplessly as Scorpius Malfoy flew into the sky after my cousin. Albus didn't see the first blow coming, and Scorpius' fist hit him out of nowhere. He wobbled, but being the incredible flier he was, he stayed aloft. But he didn't even have time to think before he was hit again. Scoprius punched him in the gut on a flyby and soared off laughing. I could see Al's face contort with pain as he lost grip. He slipped from his broomstick and begun tumbling to the ground.
I covered my ears and screamed, but I still heard the sickening crunch as Al's body smashed into the ground. I tried to run to him, but Scorpius landed behind me and pulled me back. Before I could speak, he performed a lip-locking jinx on me and Teddy, ensuring that we could never tell anyone what we saw.
Once he let me go, I spun around and punched him in the nose. I heard the cartilage in his nose bend and snap, and his lip was bleeding, but it wasn't good enough. I would have stood there and beaten him all day if I could, but I had to get to Albus.
I was at his side in seconds, and I could see that he was badly hurt. His arm was broken, and at least eight ribs along with it. His leg was bent wrong, too. He coughed, and blood came up with it. Lying next to him was a note with three words written on it in Teddy's familiar scrawl.
"Gone for help"
After that everything was a blur of tears and blood. I remember Albus being carried to the hospital wing and Ms. Bones pushing me out, saying something about how Albus needed peace and quiet. Teddy had comforted me, telling me everything was going to be alright.
After my tears faded out, they were replaced by something far harder to soothe… Anger. And a grudge I would hold for years to come.
RR please!:) If you have any concrit, I would love to read it!
