Scorpious Malfoy and Lily Potter were most unlikely friend, but friends they were. Draco Malfoy and Harry Potter were work colleagues then acquaintances, then friends.
Draco often came to the Potters for lunch. Then, when he had a son, he brought baby Scorpious with him too.
Scorpious was at the Potters house every other weekend so they all grew up together. Scorpious, James, Albus, Rose, Hugo and Lily.
While Albus and Rose became friends so did Scorpious and James, Lily and Hugo. They were well matched in age.
When James and Scorpious went to Hogwarts they drifted, slipping into the house rivalries. Scorpious was, of course a Slytherin and James a Gryffindor. They, in time became enemies, always taking it too far.
Now when Scorpious came to the Potters house he sat alone. Until little Lily Potter approached him.
They became closer and closer.
Then came her first day at Hogwarts. Scorpious remembered it well.
Scorpious had been filled with dread for weeks. He didn't want the same thing to happen between him and Lily as it did with James. Lily was his only true friend now. She knew him better that even he did at times.
Lily had looked so nervous as she walked into the hall and Scorpious found himself staring. Memorising her features before their paths separate, as they knew they would.
As Lily had sat on the stool he saw her eyes dart between her brothers and cousins and himself. He had wondered what he was thinking.
Once the Hat was over her eyes Scorpious noticed the Gryffindor's preparing to applaud.
His while world seemed to stop as the Hat opened it folds and shouted;
'SLYTHERIN!'
Lily looked as shocked as if someone had just hit her. She stumbled dazedly towards the Slytherin table and slid in beside the other first years.
She had spent that night with her brothers, crying.
Scorpious still smile at the thought that Lily was in his House.
Lily hadn't made many friends at first and had spent her days in the library. Then Scorpious found her and they became attached at the hip.
They became best friends. Fast. They had always been alike and found they had more and more in common.
Lily went to Scorpious with her problems and he went to her with his.
They were as close as friends could be, and then some.
So it really wasn't surprising when Scorpious realised he liked her.
