"Remind me why you three have got detention again?"

The next day at dinner Remus looked around at his three friends wondering how on earth they had managed to once again land themselves a weeks worth of detentions when he had only left them alone for a single night.

"Well we were just exploring the castle when McGonagall caught us," covered James. "We would have let you come too but we couldn't find you. Where did you say you were?"

"Yes but if I had gone with you, I would also have a detention tonight," replied Remus evasively. It had been a rough night and he knew that his friends would have noticed his pale face, tired eyes and the scratches that covered his body. However they did not ask about it; whether it was because they knew he wouldn't tell them or because they knew he wouldn't tell them the truth. Remus hated lying to them but he couldn't tell them the truth. He wouldn't.

"You didn't answer the question," said Sirius narrowing his eyes.

"Didn't I? Well I…erm….I fell asleep in the library again. Speaking of which, I have to go. Lots of work to do." With that Remus got up and left the Great Hall.

"Do you ever get the feeling that he's hiding something from us?" asked Sirius sarcastically.

"We need to find out what he's up to but we can't get caught following him again. McGonagall would throw a fit."

"Or we could just leave him alone?" Peter, who had been shovelling food in his mouth through the entire conversation, asked the question without really thinking only to find James and Sirius looking at him incredulously. "It was only a…..a thought."

"What kind of friends would we be if we didn't find out what he is up to?" asked James a smirk on his face. "The only question is how are we going to find out?"

"Yeah following him hasn't exactly worked out well so far has it?" said Sirius running his hand through his hair.

"Not exactly no. All we found out from last night is that the teachers must be in on it and Peter can't lie to teacher to save his life."

"Who said the teachers were in on it? I couldn't see who he was with could you?"

"No, but if they weren't McGonagall have caught them at it by now and they weren't exactly sneaky about it were they. I mean its not like they don't do it very often is it? It happens every month."

"Okay I agree. The teachers must be in on it. So that means he must have a good reason for it. But then again its Remus, of course he has a good reason for it," Sirius said rolling his eyes.

"Yeah he isn't known for his spontaneous rebellion is he?" laughed James.

"We could just ask him," suggested Peter nervously.

"Pettigrew weren't you paying attention?" asked Sirius. "We tried that and he just makes up some lame excuse and leaves the room."

"Which must mean that it's a big deal; otherwise he'd just tell us right?"

"But why wouldn't he tell us anyway? I mean we are supposed to be his friends," said Peter.

"I dunno," said James deep in thought. "Maybe he's not proud of whatever it is."

"Yeah it would make sense if he was ashamed of it," stated Sirius.

"But what could it be?"

The detention with McGonagall lasted hours and after it was over both James and Sirius had a lot of work to catch up on. Peter having already copied what Remus had done earlier in the night had gone to bed and James and Sirius were left alone in the common room.

"I hate McGonagall," huffed Sirius, flicking lazily through Fantastic Beasts and Where to Find Them.

"Hhmm," said James as he added something to his essay.

"I can't even remember what I'm looking for," cried Sirius putting the book down and reaching for his own half-finished essay.

"You're looking for Red Caps and how to repel them," recited James without looking up.

"Oh yeah." Sirius picked the book back up and flicked through to the index but on his way he saw a picture that caught his eye. He stopped looking at it. It was a picture of a man half covered in fur and his arms stuck out at weird angles; his face was screwed up in agony. The caption read:

The transformation of a werewolf can sometimes be a painful experience for the witch or wizard, illustrated by…..

"Oi James. Look at this," said Sirius holding out the book for James to see. James winced at the picture.

"Looks bloody painful too. Imagine going through that every mon-" James froze as it clicked. "You don't think…."

"What?" Sirius looked thoroughly confused by his friend's behaviour but James didn't reply; he just sat there staring at the picture with wide eyes. "I don't think what?"

"You don't think Remus is a….a….."

Then it hit Sirius too. "A werewolf? Your losing it." Sirius tried to laugh it off.

"But he goes away every month and he's always covered in cuts and bruises. What if…."

Sirius looked unsure but then a thought struck him. "One way to find out," he said as he ran up to his dormitory to retrieve a piece of homework he did a few weeks ago.

When he came back down he saw James looking at him in confusion.

"What's that?" he asked.

"This is a lunar chart that we did for Astronomy. If Remus is a werewolf then he would be away every month for the full moon right?" James nodded moving their discarded homework to one side.

"Was last night a full moon?"

"Let's see…..erm…" Sirius muttered to himself as he began to work it out and then his face paled. He nodded.

"What about the time last month?"

Once again Sirius muttered under his breath as he worked it out, attempting to decipher his untidy scribbles. Once again he nodded.

"What about before that?"

They did this 5 more times before they came to the only possible conclusion: Remus Lupin was a werewolf.
