"Well then," said James "We'll start with now… You're living with your Aunt and Uncle. Your Aunt is your mother's sister."
"When I got my Hogwarts letter she was jealous, and wanted to come as well. She couldn't though as she couldn't perform magic. Sev, -do you remember me telling you about Uncle Sev? – And I were off, Sev'd been telling me about Hogwarts since I was seven; we were both excited.
"I met James and your Godfather, Sirius, on the train. Thinking them rude and arrogant boys, who called my best friend names, I hated them. We went through school in separate houses, Sev and I, as friends until fifth year, calling me a Mudblood to fit in with his house and through anger, a girl had to rescue him from the teasing James and his friends were doing." Lily continued.
"My friends and I, we called ourselves the Marauders, often teased, hurt and pranked Snape. I feel horrid now, but… then I thought it was justice against the bad guys, Slytherins… who aren't really all bad. There can be bad people anywhere… my friends were Sirius, Remus and Peter." James interrupted.
"Anyway," Lily frowned at James. "When your father wasn't such an idiot, I went out with him, seventh year. I don't think Sev liked that much… But I married your father. Sev, forced to become a Death Eater, heard a Prophecy. Just the beginning of one, he told Voldemort, an evil, dark wizard who wanted to control the Wizarding World. Finding out He was going to kill me he turned to Dumbledore for help."
"Dumbledore put the Fidelius Charm up, we'd said Siri'd be our secret keeper at the order… just in case of a spy… but made… Peter it instead. We didn't know he was a Death Eater," James continued. "Peter told Voldemort where we were, he killed Lily and I, but you survived, the Wizarding world loves you. You're their Hero."
"Sirius was put in Azkaban, even though he'd put the charm up and knew it was Peter… He took you to Petunia's too. Our Wills weren't read…" Lily finished. "We're sorry you know…"
James looked at Harry. "Did you get all that?"
"I think so."
"'Rey… You have to go back now… We are sorry. But it also should give you time to think about this, tomorrow you'll come back here and we'll teach you to control your magic. So you don't get into trouble, OK?"
Harry nodded. His parents waved. "Love you 'Rey!" whispered over his ears.
He woke in the cupboard again.
