Disclaimer: I wish I owned Remus and Sirius, but unfortunately, they belong to the wonderful J K Rowling, along with the rest of the HP world and the other characters.

Rating: PG-13 maybe, for mild slash (in later chapters)

A/N: Another MWPP story, set during their seventh year. Yes, it is Remus/Sirius slash again. James and Peter are going to find out about Remus & Sirius, and there may be other revelations popping up in future chapters... you'll have to see how it goes.

---------------------------------------------------------------------------- -----------------------------------------------

"He started it!" exclaimed Sirius, pointing at Remus, who winced.

This was the third time in a week that Sirius had tried to blame some form of trouble on him, and it was only a very small consolation that this time it was true. He had not *intended* to end up standing on top of the breakfast table duelling with Sirius, and he had not *intended* for James and Peter to join in. He certainly had not intended the chaos that ensued, their spells deflecting off each other and hitting various bystanders with... interesting results.

"Oh, as if I believe that for a moment!" snapped McGonagall.

Despite the fact that Remus' best friends were Sirius Black and James Potter, he had a reputation as a well-behaved, hard-working student. Sirius and James had an ongoing bet on how many times they could blame things on him before someone believed them. James had bet that it would take about a month. Sirius' response had been that no one would ever suspect Remus of causing trouble. He was not supposed to know about the bet, of course, but Sirius had warned Remus that he expected to win.

"There are thirteen students in the hospital wing! Madam Pomfrey isn't even sure how to go about correcting some of the results of your idiocy!"

Peter and James would have to join those thirteen students as soon as McGonagall had finished with them. There were two large batwings flapping furiously on either side of Peter's head and James was speaking backwards. Sirius' hair had turned bright blue and curly, but McGonagall seemed to be of the opinion that this served him right, and as it did not affect his working, he would have to deal with himself. Remus had come off completely unscathed. This was a minor miracle, as he had spent most of the duel laughing so hard he cried and scarcely able to get out the words for a spell.

"I have come to expect such behaviour from you, Black, but I would have thought that *you*, Potter, would have remembered the warning I gave you a few weeks ago?"

"rosseforP, noitarugifsnarT ni t'nsaw I," offered James, then grimaced. The last time he had caused mayhem in a Transfiguration lesson, McGonagall had told him that he would be thrown out of her classes if he did not behave himself impeccably for the rest of term.

Her mouth thinned visibly, and Remus winced again. This was not going at all well.

"Um..." he began and she turned her glare on him. "Actually... this *was* my fault."

Professor McGonagall looked startled. Everyone always seemed surprised when he got in trouble. Beside him, Peter started to rise towards the ceiling again; he reached out a hand and pulled him down without looking away from McGonagall.

"Detention!" she snapped, apparently lost for anything else to say. "All of you! And twenty points from Gryffindor!" Resigned, they all stared at the floor. They had not expected anything less.

"Well, go on. Your detentions will have to be after the holidays." They turned to leave. "And take those two to the Infirmary. I will expect you both in Transfiguration this afternoon, though. No excuses."

"Detention and twenty points," said Sirius as they walked away from McGonagall's office. Sirius and James were towing Peter along a few inches off the ground. "Nice one, Moony, she would never have let me or Prongs off so lightly. Mind you, if I can't fix this, I'm still going to kill you."

"So vain, Padfoot. But there's no need; it might not be quite the effect I intended, but I do know what I did." He waved his wand and muttered the counter-curse. Sirius' hair sprung back to its usual black, though it was a lot messier than usual.

"Thanks," he muttered.

"I don't suppose you know how to fix these, as well, do you?" asked Peter gloomily.

"Not a clue. That wasn't me."

"I don't think that was any of us," remarked Sirius, studying Peter's wings. "I certainly didn't."

"em roN."

They paused for a moment while Remus and Sirius figured that out.

"A couple of the spells must have got mixed," said Sirius. "Hey, if we can work out which ones..."

Remus rolled his eyes. "Don't you think we've got into enough trouble for the time being?"

"Ah, we can work on it over Easter. No teachers to complain."

"yriaF htooT eht ekil kool llaganoGcM ekam ll'ehs, esouh s'mum ym pu ssem uoy fI!" said James, and they could tell he was alarmed even through the garble that came out of his mouth. Scowling at Sirius - it was Sirius' spell that had caused his problem - he pulled out his wand and wrote what he had meant to say on the wall. The words glittered in blue for a few minutes and then faded. "If you mess up my mum's house, she'll make McGonagall look like the Tooth Fairy!" Sirius, Remus and Peter were all spending Easter with the Potters.

"Would I do such a thing?" asked Sirius.

"Yes!" chorused Peter and Remus, while James scowled and nodded vigorously.

The Infirmary was so packed that Remus and Sirius had to wait outside for their friends.

"I was thinking," began Sirius, and Remus gave a loud gasp of surprise.

"Cheers, Moony," said Sirius dryly. "Anyway, I was thinking, we really ought to be telling Prongs and Wormtail about. you know."

The smile faded from Remus' face. "Yeah, I know. I don't feel right, hiding it. It doesn't seem fair not to trust them after everything they - and you - have done for me already. I don't deserve such good friends."

"We keep telling you, Moony, stop putting yourself down. Of course you deserve us. Anyway. We'll agree to have told them by the time we come back?"

Remus sighed. "Yes. You're right."
