Prologue

It was raining hard on September 1st, 1971, as Remus stood next to the Hogwarts Express, holding his trunk and looking slightly afraid. Remus quickly said good-bye to his parents, who did not seem that sad to see him go, and found himself ushered into the train, along with many pupils who intended not to get drenched. It had started to rain just a few minutes ago, and most of the students had already got in the train by that time. But Remus had been a bit late. It was an unfortunate habit of his mother's.

Remus started walking, looking for an empty compartment, but finding none. After about five minutes, he opened a door to find three boys casually chatting and laughing. Deciding they seemed alright, Remus stepped into the compartment.

"Hello," Remus said a little uncertainly. "Can I sit here?"

They all looked at him.

"Sure," said a messy-haired boy with glasses.

Remus smiled gratefully and sat down next to the boy who had talked. He then noticed that he was the only one to be soaked wet; the other boys had obviously got on the train before the rain had started to pour.

"Have you come all the way from France, and swam across the English Channel?" drawled the boy who was sitting opposite him.

For the first time, Remus had a good look at him. He was smiling from ear to ear now, and it was a very charming smile. He had beautiful grey eyes that managed not to be cold, but joyful and mischievous. His dark hair fell on them gracefully.

"I'm Sirius Black," the boy said.

"Don't mind him," the boy with glasses said, referring to Sirius's previous comment. "I've known him for ten minutes, and he's already made fun of half of the wizarding population."

"Not in a nasty way, though," Sirius protested, still smiling.

"I'm Remus Lupin," Remus said.

"I'm James Potter," said the boy with glasses, "and that's Petter Pettigrew."

A small and rather fat boy, who had not talked yet, smiled at Remus.

"Well, I hope you're not weak-hearted, Remus," Sirius said.

"Why?" Remus asked, suddenly a little frightened.

"Why, because you're about to embark on a trip with Sirius Black!" Sirius winked.
