Okay I have changed the story slightly. Lily and Scorpius are in the same year.

I don't own Harry Potter.
Lily Potter kissed goodbye to her parents before getting onto the train. Her brothers shot off to sit with their friends leaving her to struggle with the packed corridors. She found an empty compartment at the end. It smelled like owl droppings (hence the reason it was empty) but she was just grateful to sit down. She closed her eyes and leant her head against the cool glass of the window. A small knock on the door caused her to start. She turned to see a blonde boy stood outside. He smiled apologetically.
"Hi. Sorry to scare you I was just wondering if I could....well..."
She smiled.
"Sit here?"
He nodded.
"Go ahead."
He dragged a suitcase in and sat opposite her. The boy stuck his hand out.
"Scorpius. Scorpius Malfoy."
She reached out tentatively.
"Lily. Lily Potter."
His mouth opened into a little 'o'. This was going to be one hell of a train ride.
*~*~*
Lily and Scorpius left the train together. She didn't understand her father's muffled warning about the boy. He was perfectly pleasant to Lily. Rubbish at exploding snap though. She was still laughing at his lack of eyebrows when they saw Hagrid.
"Well if it isn't little Lily Potter! How's your parents?"
Students began muttering and Lily blushed.
"They're fine. They say hi."
Hagrid grinned.
"Come on then! Firs' years this way!"
They followed him to the boats.
*~*~*
As McGonnagall gave an introduction in the entrance hall Lily looked around. She had heard some terrible stories about the Malfoys but was still shocked at the amount of glares Scorpius was receiving. McGonnagall left to prepare the hall.
"Did you imperius her then Malfoy?"
Scorpius blushed and hurriedly shook his head. It took Lily a moment to realise that they were talking about her.
"Leave him alone."
They turned to look at her.
"Definitely imperiused. Why else would a Potter sit with a Malfoy?"
At that moment McGonnagall walked in.
"We are ready for you now."
*~*~*
They filed in and the murmur of the hall got slowly quieter. By the time they reached the front of the hall it was silent save for a few whispers. McGonnagall turned to face the hall.
"Welcome back old students and to new students hello."
She picked up the sorting hat and a knot formed in Lily's stomach.
"Helen Andrews!"
And so it went on.
"Scorpius Malfoy!"
The hall broke out in muttering. Scorpius sat on the stool and the hat was placed on his head.
"Hmm...I was expecting an easy one. Yes there are Slytherin traits in there. So angry at your family. Ashamed and angry. But brave. Old habits die hard however Slytherin!"
He's clever and quick thought Lily to herself. Slytherin doesn't mean he's bad.
"Lily Potter!"
She walked up. The hat had barely been placed on her head when it roared.
"Griffindor!"
She ran to the table and was immediately hugged by her family. She threw a smile at Scorpius who shyly smiled back.
I think we're going to be friends.
She turned and tucked in to the feast.
