A/N: I'm debating whether to write a Remus/MuggleOC next or a Remus/Hermione one where Remus and Harry have to switch places (through polyjuice potion maybe) for a year. I plan on doing both, but I not sure which one I want to do first. If anyone has any preference, let me know. :)

Disclaimer: I own nothing.


Room of Requirement, 1979

Hermione sat quietly in the Room of Requirement, lost in her thoughts. She felt rather trapped, with no way home. A fresh onslaught of tears welled in her eyes. On the bright side, at least she knew some of the people here, and when she got older she might be able to see her friends. Dinner came and went without her knowing it. The hours that ticked by seemed like nothing to the expanse of time that stood between her and home.

Meanwhile, at the dinner table, the Marauders, and especially Lily, were getting worried. Katie hadn't showed up yet, and none of them had seen her since Quidditch practice. Remus had decided to keep to himself the fact that he'd seen her in the Shrieking Shack. For now, at least. He'd probably tell the other Marauders later.

James finished first, and he and Lily headed for Griffindor Tower. "Let's look on the Map," decided James.

"That's a great idea, why didn't we think of that before?" realized Lily.

The pair soon found themselves in James's dorm. He fished the Map out from under his bed. "I solemnly swear that I'm up to no good," he said. The blank parchment in his hands began to show little figures and rooms.

Lily scanned the Map, puzzled. She didn't see Katie anywhere. She was about to give up when James pointed out something peculiar.

"Look, there. It says 'Room of Requirement.' I don't remember there being such a room. And look, it clearly says that Hermione Granger is in it. We don't know of any Hermione Granger."

"Unless," said Lily slowly, "Someone isn't using their correct name." The couple looked at each other, puzzled frowns on their faces.

"Why wouldn't she use her real name? What does she have to hide?" wondered James. A determined expression lit his features. "I'm going to find out," he decided.

Lily also felt quite curious, and agreed to come with him. "Mischief managed," said James, sliding the Map into his pocket. The pair marched to the place where the Room of Requirement was supposed to be. However, nothing appeared to be there. "The Map never lies," mused James. "I'll have to try and use a spell to open it." He turned to Lily. "Together," he said.

"Alohamora!" they shouted. It didn't work. "Bombarda!" They thought they could see the outline of a door, before it faded away. "JUBEO SUPERO!" they shouted. It was the strongest spell they knew. The door appeared again, and slammed open.

Hermione looked at James and Lily, her eyes wide. How could they have found her? They didn't know about the Room of Requirement.

James marched up to her. "Pretty clever, this room," he commented. "We were worried about you, so we came to look for you, Hermione."

Hermione's eyes got even bigger. (I must try to save this situation.) "Why did you call me Hermione? I'm Katie."

James took out a bare bit of parchment. "I solemnly swear that I'm up to no good," he said lazily. He pointed to the Room of Requirement on the Map, and her real name was clearly printed next to his.

"The Marauder's Map!" she exclaimed, not stopping herself in time. "I should have known."

"Why did you give us the name Katie instead of your real name, Hermione?" demanded James. Lily just stood there, curiously wondering what was going to happen next.

"Dumbledore told me to. It's a secret," Hermione said, desperately hoping she wouldn't be questioned further.

"Obviously," said James.

"Why all the secrecy?" wondered Lily. "Can you tell us anything at all?"

"It has to do with Voldemort," Hermione explained. "Now please, I'm Katie to everyone else. It'd prove to be dangerous otherwise," she pleaded.

James and Lily felt disappointed yet intrigued at the same time. Clearly there was more to Hermione than what met the eye. "All right, we'll call you Katie. Won't we, James?" said Lily, giving him the evil eye.

"Yes, yes, we will," assured James. "We're as much against Voldemort as you are."

Lily noticed, for the first time, how upset Hermione looked. Previously she'd been too intent on finding out why she wasn't being honest with them. "What's wrong, Katie?"

"It's part of the secret Dumbledore wants me to keep. I'm really sorry, I want to tell you, but I can't." Hermione sighed, feeling rather alone. There wasn't anybody she could confide in, other than Dumbledore, and she didn't feel close enough to him to tell her everything that was on her mind.

The formings of a plan occurred to James. He, Sirius, and Peter were all Animaguses, weren't they? They could spy on her and find out exactly what was going on. Lily glanced at him, taking in the look on his face. She recognized it as the expression he got when he was plotting mischief. (I'll have to keep a close eye on him) she decided.

James clapped his hands together. "Why don't you come to the Great Hall? Dinner is on, you know."

"Really? I hadn't realized so much time had passed," commented Hermione. "Let's go, then." The trio left the Room of Requirement together.

After dinner, Remus caught up with Hermione when she was on her way to Griffindor Tower. "You don't seem to like Peter very much," he commented. "Why?"

Hermione searched her mind for an excuse. "You know how it is, sometimes. You meet someone, and for some strange reason, you just don't like then. It's something about them, you just can't explain it."

The pair was now standing still, looking into each other's eyes, both thinking the same thing. (On the other hand, there's a time when you meet someone, and you love them. It's something about them, you just can't explain it.) Remus took her hand. "I understand." He walked several yards Griffindor Tower before he realized that he was holding her hand. (What am I doing? I love Resda, I have since fourth year. How can Katie just walk into my life, and make me feel as strongly for her as I do Resda, in a day? Why do I feel so connected with her, like she knows me already?) He abruptly let go of her hand. (I can't let this go on. I must be loyal to Resda. Katie will probably end up with Sirius, he always has such an easy time of getting girls)

Room of Requirement, 1997

Harry hurried after Lupin eagerly. Finally he'd find out what happened to Hermione. On the way, they came across Peeves. At first, Harry felt irritated. Peeves would probably try to delay them. Instead, Peeves merely waved at them with a dejected look on his face and floated by. (Wow, that must be a first) Harry thought. (This is really strange behavior for Peeves)

Remus opened the Room of Requirement in record time, and the pair sat down on a couch. "Harry, I have some bad news," said Remus. Harry waited expectantly. He certainly was no stranger to bad news. "The other day, Peeves played a prank on Hermione, and the two of them ended up fading back eighteen years in the past."

Harry frowned. "She'll be able to come back soon, though, right?"

"Dumbledore said that she wouldn't be able to come back until she accepted where she was. It might take awhile. She really misses you, Harry, I can tell."

"You can tell?"

Lupin sighed. "I'm getting altered memories of her being in my past. She's in seventh year with the Marauders, Lily, and everyone else."

"Really?" said Harry, intrigued. "How is she? What is she doing?"

"She's rooming with your mother," Lupin smiled. "She watched James and Sirius play Quidditch. She spent some time in the Shrieking Shack, and..." Remus's voice faded. Suddenly he remembered Hermione entering the Great Hall with James and Lily, her eyes distant with the distinct look of homesickness. "And, last I remember, she was entering the Great Hall with your parents, feeling homesick."

"Do they know she's from the future? Did you know?" asked Harry.

"No, nobody knew except Dumbledore."

"What about you? What have you two done together?"

"I can only know things she's done around me." Suddenly Remus started feeling guilty. He knew how Harry felt about Hermione, and here he was, in his past, beginning to have the desire to steal her away from him. Sure, nothing official had happened yet, but he could feel it coming. Hermione would no doubt try to cheer him up after Resda dumped him. Then what? If Hermione liked him, would she end up as his girlfriend? (I can't control my past actions) he reminded himself. (But how am I going to break the news to Harry, if it happens?) "We haven't done much together yet. There's not much I can tell you."

Harry felt disappointed. (At least I'll be able to get news from Remus about what's happening) he tried to console himself. "Tell me as soon as you start remembering more," said Harry.

"I will," Remus promised. "We should really be getting to the Great Hall, before we miss dinner altogether."

Harry nodded and followed him out the door. (I sure hope Hermione makes it back soon)

Preview of next chapter: She sighed. "Harry, I miss you so much," she said aloud. "I can't believe Dumbledore wasn't able to send me back to the future. What am I going to do now?" A noise made her jump. She turned, and was shellshocked to see a black dog next to her, staring. (It's Sirius!) she realized. (Oh no, he's heard what I said!)
