Chapter 1: On the train
James Potter carefully disentangled himself from his mother's arms. "Oh, Bye Jamsie! Do well! Try not to get into too much trouble! We'll miss you!" she cried. James smiled and hugged his dad. "You'll do fine, son. Make us proud. And perhaps join the Quidditch team while you're at it" he added as an afterthought. James laughed and lugged his suitcase onto the train. Finally coming to an empty compartment, he put his things away and sighed contently. I'm going to Hogwarts. And nothing can stop me now
"Remeber all I told you?" came a sharp voice. Sirius Black suppressed an eye roll. "Yes, mother" he replied dutifully. "Do not bring shame upon the house of Black by associating with muggle-borns or half-bloods, Do not talk back to the teachers, be respectful to the head of Slytherin house, and do not associate with Gryffindors." he ticked each one off on his fingers. Walburga clipped him around the ear. "Good. Now go. You'll be late" Sirius groaned internally and lifted his trunk, wobbling towards the train. Knocking on a door, he heard a muffled. "Come in" and met a boy with raven, fly-away hair and round glasses. "James Potter, nice to meet you"
Remus Lupin looked around nervously. "It's alright Remus dear. The train's right there" said his mum, giving him a quick squeeze. "I'm going to miss you," he said quietly. Hope's expression softened. "I know Remus, but you can write to me. I promise I'll return every letter." Remus smiled. "Promise?" "Promise" and with that, the boy waved goodbye and wandered onto the train and knocked on a door. "Come in," said two, rather strained voices at the same time. Remus pushed it open to find two boys staring rather frostily at each other. One with round glasses, the other with shoulder-length black hair.
"Mum! Mum! Stop it, you're embarrassing me!" squeaked Peter Pettigrew, wiping his mother's lipstick from his cheek. Francie laughed. "Oh all right Peter, I know you're all grown up now." Peter's dad reached down and ruffled his hair. "Go get em' tiger," he said, smiling proudly. Giving his parents one last hug, Peter flung himself into a compartment where there were already three boys. The one with sandy hair looked like he was trying to hide in a corner and the other two seemed to be squaring off.
