A/N- The James, Sirius, Remus and Peter from the other universe will all be called by their last names

Lupin, not for the first time that week, had a blinding headache. Not literally blinding, but if he concentrated on it black spots danced across his vision and his eyes watered. So Lupin was trying his best not to concentrate on it. He tried reading his book, then writing a letter to home, and then going to sleep. Nothing worked, and the headache was worsening. He groaned and ran a hand through his hair. The headache was partially created by the approaching full moon and the stress of homework, but the largest contributing factor was the note that now currently rested on his bedside table. Unable to think of anytting else to do to distract himself from his headache, Lupin picked it up and read it again.

Dear Pupil,

An event of the most unusual and phenomenal nature has occurred. Four students have been transported here from an alternate universe. The students are as follows; James Potter, Sirius Black, Peter Pettigrew, and Remus Lupin. The Hogwarts staff are currently working on a potion to send them back to their original dimension. We thank you for your understanding, and if there are any questions please contact your head of house.

Headmaster Albus Dumbledore.

When Lupin first received the note he had thought it was a practical joke. Perhaps from that rowdy bunch of Hufflepuff seventh years, or those prankster Gryffindors he shared a dorm with. But after running a couple spells and finding that Dumbledore's signature was not forged, he read it again. And again. When he read it the fourth time he managed to get past his shock of alternate universes and realized that his name was among the short list of students transported here. How? Why? He wondered, but no immediate answers surfaced. The only logical explanation was that James, Sirius and Peter were making it for fun and he was somehow at the wrong place at the wrong time. He would have never been included in a project such as this. He and the other three Gryffindor fourth years were far from friends. Finally he decided upon the most reasonable course of action; wait. Eying the new bed and the suitcase of clothes, Lupin deduced that his other self would be arriving shortly, and then he would have plenty of time for questions. He couldn't resist the bubbling feeling of happiness coursing through his veins. He would have a friend, if only for a short period of time. He would have someone to talk to, someone who would walk with him to classes, someone who he could complain about his pain. Already that thought made his headache lessen slightly. Lupin had not made any friends when he arrived at Hogwarts. James, Sirius and Peter quickly became fast friends, but they wanted nothing to do with him. Nor I them, Lupin thought bitterly, but he quickly shook his head. No, he thought, I can't think like that. It's better if we aren't friends. If were closer they might begin questioning where I go every month, and that would lead to them discovering what I am. I'm lucky even to be here, I should appreciate that. Even though Lupin found these thoughts perfectly reasonable, they did not lessen the hollow ache of loneliness in the pit of his stomach. But Lupin had grown so used to it he barely even noticed it anymore. Abruptly his headache flared, and Lupin put his head in his hands in pain. He stayed like that for a few moments, before flopping himself down on his bed. Why wasn't his other self here yet? He wondered, and as if timed perfectly Remus walked into the room.

Lupin shot up into a sitting position immediately. Remus shut the door quietly behind him and looked at his other self. The first two words that came to mind were unhappy and unhealthy. Lupin's face was pale and his mouth pulled down into a subtle frown. His eyes practically gave off vibrations of unhappiness and exhaustion. His hair was tangled and stringy, he was slightly hunched over and the scars covering his face seemed to pop out in contrast to his pasty skin. While Remus was observing Lupin, Lupin was doing the same.

Remus looked healthier, and his skin was slightly tanner from days lounging in the sun. His eyes were tired but unlike Lupin's, they also looked happy. He was standing straighter and unless you knew where to look you could barely notice his scars.

"Um, hi." Remus said awkwardly. Spotting his new bed he went and sat down on it.

"Hi." Lupin said, and there was a short silence.

"So I'm you," Remus stated.

"And you're me," Lupin said, and then cringed inwardly. Way to restate what he just said.

"Yeah…" Remus trailed off, unsure of what to say. Lupin thought frantically of all the questions that had recently been bouncing around in his brain, but he couldn't remember a single one. There was another short period of silence.

"Want to play chess?" Remus asked suddenly, and Lupin quickly accepted the offer, glad to be doing something.

~At McGonnagol's Office~

Professor McGonnogal swished her wand and the door locked. Sighing, she sat back down at her desk and flicked her wand so all the hairs that had escaped out of her bun went back to their place. Today was frantic. Gryffindor students were coming in by the dozens, all holding notes in their hands and questions on the tip of their tongues. She had answered every single question that had been fired her way, from well-thought out to plain stupid. (Though of course she didn't say that to the students' faces.) Now she just needed time to relax. While she answered all of her student's questions to the best of her ability, she still had some questions of her own. What potion brought them here? Why did Horace have a book about alternate universes? Merlin, why those four students? Why?

She would have to go and speak to Albus later. For now, she would just rest.

~At Dumbledore's Office~

Black shifted from foot to foot, eyes darting around excitedly. He had just received his note, and was eager to meet his other self. Upon Sirius's request, Black would meet him right outside Dumbledore's Office. Right now he was chatting with Potter, while James was talking with Peter. Potter was saying something about Remus Lupin, but Black wasn't really paying attention. He was surprised at first to hear that Remus was here as well, but it did get a little boring listening to Potter rant on and on about him. Finally Black heard footsteps, and out came Sirius…..looking distinctly disgruntled.

"I cannot believe this!" Sirius exclaimed, brandishing a piece of paper. Upon closer look Black realized that it was Sirius's schedule.

"What?"Black asked, and James and Peter stopped talking to look up.

"Remedial Potions!" Sirius shouted, and James stifled a laugh. Black glared at him.

"So what?"

"Why on earth are you, well I guess it's I…or is it we? Whatever! Why are you failing potions?" Sirius looked annoyed. He hated potions enough as it was, and now he had to do even more!

"Relax. I use that time for planning pranks." Black smirked, and Potter snorted. Sirius stared.

"I'm all for pranks, but I don't want to have to sit through potions twice because you can't find time outside of your classes to plan!"

"Whatever," Black said, rolling his eyes. It was clear he didn't want to talk about it anymore. Sirius sighed; he felt like such a killjoy, but he didn't want to apologize.

"C'mon, let's go to the dorm." Sirius said, and marched off. Black followed, scowling. As James walked up to Dumbledore's office, he began thinking that maybe this universe wasn't going to be as fun as they thought.
