Beware the Ides of March

Prologue

James, Sirius, and Peter were lazing around in their second year dorm in Gryffindor Tower. They just got out of detention for a prank they pulled on Snape in potions a few days before. Their prank made the potions classroom explode and Slughorn was not happy about it. It was an accident. They only meant to make Snape's potion explode.

Remus was in the library studying with Lily, saying he needed to get away from them before he went insane.

The three boys were sitting on the floor in the center of their room. They had a book between them and were staring at it wide eyed. Sirius looked angry and shocked. James just sat staring at it upset and angry to. Peter looked scared and like he was about to wet himself. They took the book from a third year when they heard what the third years were learning about in Defense Against the Dark Arts.

The third year was annoyed when they asked to borrow his book, but complied and handed it over to get them to leave him alone. Now, they wished that they never asked for the book.

Now the three boys were having an argument over what they read in the book.

"It's not possible." Sirius growled, looking at James angrily. "He would have told us. We're his best friends. He wouldn't keep something like this from us."

Peter whimpered.

James shook his head, frowning. "I know. He's suppose to be our best friend. If we were just friends, I would understand why he didn't tell us, but we're best friends. Best friends don't keep secrets like this from one another."

"W-what should w-we do?" Peter asked, nervously.

James glared at Peter. "Will you relax? Remus isn't going to hurt you."

"But he's a werewolf." Peter whimpered.

Sirius glared at Peter to. "He's only a werewolf once a month. The rest of the time he's just Remus."

"Yeah. He just goes a little crazy and gets a little furry once a month. No reason to be scared of him. He's still just friend." James replied.

Peter nodded his head, a little bit calmed down. "So, are we going to tell him that we know what he is?"

"Not yet/Yes." James and Sirius said at the same time.

Sirius turned his glare to James. "What do you mean not yet?"

"We're going to drop hints to let him know that we would never abandon him for anything." James explained.

"Fine." Sirius grumbled. "But I'm freaking him out as my revenge against him for not telling us the truth and for all the lies he told us."

James raised a brow. "How are you going to do that?"

Sirius ran a hand through his hair. "I don't know."

James rolled his eye. "This freaking him out thing is going to make him aware that we know, right?"

"Yeah. But it's also going drive him insane. I just don't know what to do yet." Sirius answered.

"When is the next full moon?" Peter asked.

James crawled over to Remus's trunk and used an unlocking spell to open it. He pulled out Remus's lunar calendar. "It's March fifteenth."

"How am I going to drive him insane? How?" Sirius talked to himself, rubbing his chin thoughtfully and pacing around the room. He looked at his friends still sitting on the floor. "You two have to help me. I won't be able to do this without your help."

James sighed. "Driving him insane is your way of telling him we know."

Sirius smirked evilly. "Of course."

Remus watched his friends suspiciously. They had come into the library fifteen minutes ago and haven't run screaming out of the library yet. Even weirder was that they came in here of their own free will. No one forced them to come in here.

Lily shook her head with a smile. "Remus, just forget your friends for now."

"How can I? They never come to the library in their free time. They have to be up to something." Remus replied, worry in his eyes. He kept watching his friends until they disappeared behind a book shelf and he lost sight of them.

"They are always up to something. Relax, will you? You have nothing to worry about. You guys never targeted one another. It's probably for another stupid prank against the Slytherins. I can't wait for them to be expelled. I can't believe you hang out with them. They are so immature." Lily ranted angrily.

Remus raised a brow. "You okay, Lily?"

Lily took a deep breath and nodded her head. "Yes. Sorry about that. I just can't stand Potter or Black."

"It's alright, but keep in mind that they are my friends." Remus replied.

"Right. Sorry Remus. Let's just get back to our homework." Lily said.

Remus smiled and nodded his head. Soon, he forgot all about his friends being in the library because he was working so hard on his homework and talking with Lily.

Sirius groaned and rubbed his eyes tiredly. "I can't figure anything out. How are we suppose to figure out a way to drive Remy insane? We've never been able to pull anything over him. We have to do this perfect."

James glared at Sirius. "I hate you. I can't believe you dragged us into the library."

A third year looked up from a book she was reading and glared at them. "Be quiet."

James looked at the book she was reading. "Sorry. What are you reading? It doesn't look like a book about magic. And who is Shakespeare?"

"Shakespeare is a famous muggle play writer. I learned about him in Muggle Studies and am reading one of his plays." The third year explained.

"Can I see the book?" James asked.

The third year sighed. "Will you go away if I show it to you?"

"Yes." James replied.

Sirius looked at the book to. "Why did you want to look at it?"

"I'm curious. I might take Muggle Studies next year." James replied. "It might impress Evans."

Sirius rolled his eyes. "Figures. Just give up on her."

"Never. She will someday go out with me and we will get married and have many children." James said.

Sirius frowned and hit James in the back of the head.

James glared at Sirius and looked back at the book. "Who is it in the press that calls on me? I hear a tongue shriller than all the music. Cry "Caesar!" Speak, Caesar is turn'd to hear."

"Beware the ides of March."

"What man is that?"

"A soothsayer bids you beware the ides of March."

Peter looked confused at James. "Beware the ides of March? What does that mean?"

The third year took her book back from James. "Beware the ides of March. The ides is the fifteen of March. It means that something is going to happen on the ides of March so the soothsayer warned him to beware."

Sirius eyes lit up. "Thanks." He grabbed James and Peter and pulled them out of the library. "That gave me a great idea."

"What? Are you going to go around for the next fifteen days telling Remus to beware the ides of March?" James asked, sarcastically and rolling his eyes.

"Yes." Sirius replied, ignoring the sarcasm.

James looked at Sirius like he was crazy. "You can't be serious."

"I am to Sirius." Sirius replied.

"That joke is really old." James said. "And I meant you can't be really thinking about doing that."

Sirius pushed the two into an empty classroom and locked the door. "Think about it. March fifteen is the next full moon. We can go around and tell him to beware the ides of March. He won't know what we're talking about because he doesn't know that we know that he's a werewolf. So, we say it all day for the next fifteen days. We can freak him out."

James stared at Sirius. "You really want to do this?"

"Of course." Sirius replied. "So, are you in or out?"

Peter smiled. "I think it might fun. I'm in."

James sighed. "Fine. But he better not figure out until the last day or this isn't going to be fun."

Sirius smirked. "Perfect."

A/N: This was originally going to be a one-shot. But then I realized there was too much I want to do for it to be a one-shot. So, now it's a multi-chapter story.
