"Remus Lupin and Sirius Black?"

Professor Slughorn looked at the small and fat boy with suspect. "They're here, my son." he replied for both boys. "But as you see, this is Potions and it's a quiet important subject for both Mr. Lupin and Mr. Black."

The small boy snorted unwillingly. He looked very shy. "Yes, Professor. I mean— I'm sorry, Professor. But Dumbledore himself wants to see them."

Slughorn raised an eyebrow. He looked like a man who didn't know what to do, but acted like he did know all. "Oh," he said. Taking a deep breath, he turned to face Sirius Black and Remus Lupin. It was obvious they didn't know about each other's existence but were in the same class. "Off you two go then."

Sirius Black carried a black, shoulder bag with himself. He didn't even bother to look at Remus and just walked to the small fat boy. Remus however, was slower and kinder. "We're sorry, sir," he said to Professor Slughorn. "I don't know what's happening."

Slughorn shrugged in a careless way. "Not important, boy. Tell Dumbledore I say hello."

Remus approved with his head and left Potions class with the other two boys. Walking through the corridors, he kept asking questions to the small boy. "What's your name?"

"Peter," The small boy said. "Peter Pettigrew."

"Why did Dumbledore asked for us?" Remus asked, then looked at Sirius Black, who acted like he wasn't listening to the conversation. "I mean, the two of us?"

Peter shrugged. "I don't know," he said. "You can ask for yourself when we arrive."

After that, Remus stopped talking. It took three minutes to the Headmaster's Office, and when they arrived, Peter left them without saying a word. He was a Gryffindor but he seemed too diffident. But, considering it, so did Remus.

When they entered Dumbledore's Office, Sirius didn't even bother to knock the door. He looked very formal and classic with his long black hair and black coat, but didn't show the kindness to knock. Remus didn't know the boy at all, but he could tell that his family was important. Otherwise, he couldn't be this confident. "You asked for us, Professor," he said, with a hint of kinkiness on his face. Dumbledore stood up and walked to the boys. "Oh, yes," he said. "Sit, boys. Sit please." He showed the two empty chairs. Sirius waited for Remus to sit down, then sat on the other chair. "Yes, sir?"

Dumbledore went back to sit on his big chair behind the desk. He looked at his phoenix, smiled, then looked back at Remus and Sirius. "I don't intend to mumble or take your time." he simply said. "A Death Eater is on the loose."

Sirius stiffened, Remus started to shake. Since Dumbledore called for Sirius and Remus, Remus knew well enough which Death Eater that was. A werewolf. Fenrir Greyback.

Even though Remus already knew, Dumbledore silently said his name. "Fenrir Greyback. Now you probably know why I wanted to see you two."

Sirius looked at Remus— just slightly. "What's your problem with that?"

Since he called a man 'that', he must hate him, Remus thought. "He did bad things to me."

"Like what?"

Remus didn't want to answer that and Dumbledore knew, so he immediately said, "Sirius," to the raven haired boy. "I want you and Remus to participate in a mission."

Sirius laughed a little. "A mission?" he said. Then with a grin, "Me and James can take care of so many things together, as you know, Professor."

Dumbledore slightly smiled, but dismissed the boy's offer. "No," he said. "I want Remus to be in this, too. He deserves to know everything about Fenrir Greyback."

Sirius raised an eyebrow at that, but didn't say anything. "Okay," he said. "Do you have a problem with working with me?"

Remus at first didn't understand the question was asked to him. Then, when he realised, "Oh— no, no— I mean, it's okay— to work together."

Dumbledore clapped very slowly and smiled. "Excellent!" he said. "The situation is— Greyback is on to something. I'm afraid what he's after is Remus. He has allies in Hogwarts and I'm afraid those allies are students." He turned to Sirius. "I can't tell you what it's about since it is Remus' personal privacy, but if you don't want to help us with this, I would understand."

Sirius shook his head. "Greyback serves Voldemort." Remus looked at him with a shock— since no one was brave enough to speak of his name in public. "He serves my disgusting family. Of course I'll help."

Then he looked at Remus. "What was your name again?"

Remus stiffened. "Remus. Remus Lupin."

He offered his hand to the boy in front of Dumbledore. "I'm Sirius Black," he said, as if Remus didn't know his name at all. He looked at Sirius' almost-hazel eyes and shook his hand. Then, Sirius took his shoulder bag from the ground. "We'll go now, sir." he said. "So, as I understand, you want us to figure out who helps that thing get information about the castle and Remus?"

Dumbledore nodded. "Yes. Off you two go and discover things together." he smiled. "But in that time, take care of each other."

Remus looked at Sirius. I don't even know this boy, he thought. Then another thought that didn't belong his brain came all of a sudden. You will.
