If He's Not Who They Think He Is
Chapter 4
I don't own Harry Potter

"Professor Lupin, may I have a word with you after dinner?" Dumbledore asked one day at dinner, about a week after the first night Harry had come to my room to talk.

"Of course Dumbledore," I said, nodding my head to the older wizard.

...

"So, Remus," Dumbledore said, leaning back in his seat and steepling his fingers in his office after dinner. "I have noticed that Harry has been visiting your office frequently and I know he can't be doing so badly in his Defence Against the Dark Arts that he needs that much tutoring."

"He just needs someone to talk to. His friends don't understand and he doesn't feel comfortable coming to you about it," I explained, "He still doesn't know about me and Sirius. He still thinks of me as Uncle Moony. No more, no less."

"You know you can't tell him Remus. He can never know that you and Sirius are his birth parents."

"I know Albus, I know," I whispered, hanging my head. "Can I go now?"

"Yes, just be careful Remus. I don't want to see either of you getting hurt."

...

"What is he doing at Hogwarts?" I asked myself when I saw a tiny dot labeled 'Sirius Black' on the Marauder's Map.

I quickly tapped it, whispering "Mischief managed," and set off, running out towards the Whomping Willow.

"Remus," Sirius whispered when I entered the room he and the children were in.

"Uncle Moony, how did you find us?" Harry asked.

"I still have the Map Harry," I told him. "Where is he Sirius?" I asked, turning to my ex-lover.

He stared at me, then wordlessly pointed at Ron.

It took me a moment before it clicked. "Ron, can I see Scabbers?" I asked, reaching out for the rat.

Ron cautiosly took the rat from an inner pocket in his robe and handed it to me.

I cast the Body Bind Curse on 'Scabbers' before setting him on the floor, casting the spell that would force an Animagus into human form.

The rat grew before our eyes, becoming Peter Pettigrew.

"H-Hello Remus, Sirius," Peter said nervously.

"Peter," Sirius said cooly, "Why did you do it? Why did you tell him were James, Lily, and Harry were? They trusted you! You were their Secret-Keeper!" he yelled.

"He...He would have killed me if I hadn't. I didn't want to die," Peter whimpered.

"We would have died for you," Sirius said in an enraged whisper. "Any one of us would have died for you."

"Come on, we're taking him to Dumbledore and Fudge. They'll question him and get the truth out of him," I said, releasing the spell that was keeping Peter human but leaving on the Body Bind Curse and putting him in my pocket.

"Let's get back to the school."
