Eleven is a terrible age to be. They're young and they're scared and the majority are falling head first alone.
Scorpius was one of them. He had no older siblings or cousins. His parents had few friends and even less had kids. Once he stepped on the train he was alone. But not afraid, for the simple fact that Malfoy's never are, and that's just as terrible as being eleven.
So Scorpius walked onto the train alone and looked for a place to sit and, as all friendships on the Hogwarts Express are made, everywhere else was full.
