He's Not Who They Think He Is
Chapter 2
I don't own Harry Potter

September the first came right after the full moon the year I agreed to teach Defence Against the Dark Arts at Hogwarts. It was Harry's third year at Hogwarts. Just because I had given up my son didn't mean I didn't keep track of him on the calender at least. It had been almost 12 years since I had seen Harry. Or Sirius

It being the day after the full moon I fell asleep on the Hogwarts Express as soon as I sat down.

Harry and Sirius haunted my dreams, as usual. But Harry wasn't a baby, like he normally was. He was 13 and surounded by friends.

I stirred when he was confronted by a blonde Slytherin boy, but I only truely woke up when the dementors entered my dream.

There were dementors in the carriage for real and I quickly cast my Patronus to get rid of them.

"Is everyone okay?" I asked, looking over the children. With a start I realized these were Harry's friends from my dream.

"Everyone except for Harry is sir," the brown haired girl answered. "He fainted when he tried to face the dementors."

I made my way to Harry's limp form, checking his pulse and breathing. As I was moving back he stirred.

"Mom?" he muttered, one hand on the back of his head, using the other to push himself up.

His hair was in his face and I had to resist the urge to brush it away. "Actually I'm your uncle," I said, pulling some chocolate out of my briefcase. "Not officially, but honorary. Here, this will help you feel better," I said, offering him a piece of chocolate.

"Thanks," Harry said, accepting the chocolate and taking a bite of it. "Did anyone else see that?" he asked his friends.

"Malfoy did," the ginger haired boy said glumly.

Harry groaned, "Now that story'll be all over the school by the time we're in the carriages."

"How far are we from Hogwarts?" I asked, standing and returning to my seat.

"We should arrive within the hour, we should change," Harry said, opening his trunk and pulling out his robes.

"So, are you our new Defence Against the Dark Arts teacher?" Harry asked once he and his friends were changed into our robes.

"Yes, Dumbledore asked me specifically to come and teach."

Harry nodded, "Did you really know my mom and dad?" he asked hopefully.

My heart gave a twinge. He was refering to James and Lily as his mom and dad, not me and Sirius. "Yes, I met them in our first year. We were all Gryffendors. They couldn't stand each other until our...sixth year. Then they were inseperable, got married right out of seventh year, you came along about two years later."

"And what about Black?" the ginger haired boy asked eagerly.

"Ron be quiet, let him talk," a ginger haired girl, who must have been his younger sister said, smacking his arm.

"That's all I have to say for now, but maybe you can introduce yourselves," I said, suppressing a smile as the brunette girl flushed bright red.

"I'm Ron Weasley," the ginger boy said, sticking his hand out to shake, "Third year."

"I'm Ginny Weasley," the one I guessed was his sister, "Second year."

"Hermione Granger," the brunette girl said once her face was less red, "Third year."

"Neville Longbottom," a round-faced brunette boy said, "Third year."

"Luna Lovegood," said a dreamy-eyed blonde girl from behind a copy of The Quibbler. "Second year."

Harry grinned, "All Gryffendors, except for Luna, but we won't hold it against her. Will you please tell us about Sirius Black? Please Professor Lupin?" he asked, begging for more information.

"I'm sure you don't want to hear an old man reminising about his glory days," I told Harry.

"Please Professor," Harry begged, looking so much like his father when he wanted something.

"Alright, on one condition," I said.

"Anything," Harry said eagerly.

"Call me Uncle Moony. Outside of class at least. All of you."

"Okay Uncle Moony," the kids choursed, looking at me with wide eyes.

"Well Sirius and James were inseperable our first four years. Sirius and James grew apart when Sirius and I started dating. He didn't like the idea of two of his best friends dating each other. When James and Lily started dating James saw how stupid he had been and they made up. We were a family again, us and Peter. We were a family.

"Sirius and I were the first to see you after you were born Harry," I said smiling, "You were so tiny I was afraid I was going to break you when I held you.

"I never expected Sirius to tell anyone where you were. He was so protective of you," I finished quietly, wiping away the tears that had started to fall down my face.

Suddenly I found myself at the center of a group hug. "Don't worry Uncle Moony. We're all here for you," Harry whispered into my ear.

I hugged Harry back tightly. "I know Harry, I know."
