Chapter 1:

Hermione Granger was walking down the seventh floor hallway. It was the middle of her fifth year, and despite all of the work they were doing in the DA, she still wanted to practice more. Now that she knew about the Room of Requirements, Hermione could just tell her friends she was going to study, and then come up to it. She had even begun taking her homework up and requesting the books that she needed from the room. Tonight Hermione was frustrated, she had just tried to help Harry and Ron study for their History of Magic OWL, and they had spent the whole time joking around. Usually when she needed to relax, Hermione just grabbed a book and read. However, her frustration was to the point that she needed to hex someone. All Hermione wanted to do at the moment was escape her life.

'I wish could change my life,' Hermione thought, she had come to the door of the Room of Requirement, but she didn't notice. Instead, Hermione started pacing, 'Sometimes Harry and Ron are just so frustrating, and I want to scream,' Hermione was almost in full rant mode now, 'They are just so frustrating, I almost wish I had different friends. A new life would definitely make some things easier,' Hermione turned, and saw the door of the Room before her. Not noticing that it looked different, or really thinking about what she had been thinking about, Hermione opened the door and walked through, 'Though I would miss them,' was Hermione's last thought before she felt herself falling, and the world vanished in a swirl of color.

"Hey Prongs," Sirius Black shouted to his friend as he prepared to whack a Bludger at him. Sirius was the best Beater on the Gryffindor team, and James (also known as Prongs) was the best Chaser. Being great friends, they always practiced together, "This one is coming right at you!" Just after Sirius hit the Bludger, he saw a girl appear in front, and slightly above him. Shocked, after all it wasn't everyday a girl appears in thin air, Sirius took only a second before diving in order to catch her.

"Padfoot," James Potter shouted at his friend, preparing to taunt him for missing, however, the urge to taunt was dismissed when he saw his friend diving for what looked like a person. Shocked, James flew towards where they were, he wanted to know what had happened. Once Sirius had caught the unconscious girl, and they had both landed, James asked, "What happened?"

"I have no idea," Sirius replied, looking at the girl in his arms with a sense of awe. She was gorgeous, but not in the way that Sirius normally thought girls were. She had extremely curly brown hair that looked as though it had survived a hurricane, and come out the worst for it, and her skin was paler than most, but not unnaturally pale, or daintily pale, it merely looked as though she spent too much time inside. She had a small frame, and was light, Sirius was carrying her with ease, and she practically fit in his arms like a child. However, despite her small stature, her features betrayed a maturity and elegance that most teenage girls could only dream of. Sirius smiled, this girl may not be the type of girl he normally admired, but something was drawing him to her.

"Who is she?" James asked, his curiosity was now almost insatiable.

"I don't know," Sirius replied, looking up from her face, "I'll take her up to Madam Pomfrey, why don't you get Dumbledore? You know where his office is, after all," Sirius had a combination of a smirk and a smile on his face.

"Madam Pomfrey!" Sirius called into the infirmary. He was only slightly out of breath from having basically run all the way carrying Hermione.

"What did you do this time, Black?" Madam Pomfrey asked suspiciously, but when she saw the girl in Sirius' arms she went into full nurse mode, "Oh my goodness! Put her on the bed. What happened to her?" Once Sirius had placed Hermione on the bed, he was pushed out of the way as Madam Pomfrey bustled around her trying to figure out what was wrong.

"Mr. Potter, what happened that was so important that you dragged me to the hospital wing?" Dumbledore's voice held thinly veiled amusement, but was stern enough to make James drop the old wizards arm and grin sheepishly.

"Sorry sir," James said, "I was just worried about her," he pointed at Hermione as he said this, and Dumbledore forgot about James as he went to inspect the newest addition to Hogwarts.

'Hmm," he thought, 'She looks a bit like a timetraveler.' In his youth, Dumbledore himself had done a little meddling with time. It had been around the time that his sister had died. He could remember that day like yesterday, his misguided brother had attempted to put a stop to Gellert's plans, and the three of them had become engaged in a three-way duel. At the time, none of them had known who had killed Ariana. However, after her funeral, when Aberforth blamed him, Albus just had to know. He had sent himself back through a time portal. He watched as he shot an Impedimenta curse at his brother, but it missed and had hit Ariana instead. The curse threw her against the wall with such force that she died. Instead of leaving immediately, Albus watched as his lover left him at his brother's mercy. In that moment Albus Dumbledore promised himself, the only one he trusted, that he would get his revenge on Gellert, then continue with his plans, and lead the takeover himself. So it was that Dumbledore had gone on with his life. Having been in Slytherin, (A/N I know that isn't true, but bear with me, I promise it is the only intentional inaccuracy that I will make, any others feel free to tell me, and they will be changed) Dumbledore always looked for the advantages of things. Once he saw how the hero worship people gave him allowed him access to places that no normal civilian could go, he decided to play the good guy. So he bided his time. While Transfiguration professor at Hogwarts, Albus noticed Tom Riddle's interest in the Dark Arts. Outwardly he tried to turn him away from this path, but inwardly he celebrated. If Riddle became what others would call evil, then it would allow Dumbledore to gain followers that he could later ease into his Dark Kingdom. Albus had decided that if he planned his takeover in the same way Hitler (one of the only decent Muggles, according to him) had, then he would get the power without having to deal with those who disagreed. Dumbledore was pulled out of his memories when he saw the girl stir.

"You two may go," he told the two boys who were still there. When they looked ready to protest, he fixed them with a stern look. Sighing, knowing they would get nowhere with Dumbledore, the boys left. Noticing that Pomfrey was in the room still, Dumbledore did some quick thinking, "You should go take a break," using a small form of mind-magic, Dumbledore made sure that Pomfrey didn't know that the girl had moved, "I will watch her, and if she moves I will send a Patronus." Pomfrey looked at her patient, before nodding and leaving, she was feeling a bit tired. Dumbledore smiled at how easy to manipulate his Professors were, and how easily their minds were influenced.

Hermione became conscious slowly. She looked over, and saw Dumbledore standing beside her bed. She frowned when she noticed that he didn't look quite as old as he had when she left, but she just filed the information away. Looking around the hospital wing, Hermione noticed that it was bright and sunny, looking like a perfect spring day.

"What happened? How long have I been here?" she asked, looking to Dumbledore for answers.

"That is what I would like to know," Dumbledore said, he had decided not to say anything about what he knew until he had learned more about her. Seeing her confused look, he decided to give her a small push to tell him what had happened, "Mr. Black brought you up from the Quidditch field, where you apparently appeared above," Dumbledore saw a flash of shock and confusion on her face.

"Mr. Black?" she asked, "There isn't a Mr. Black at Hogwarts." The girl said it with such finality that made Dumbledore want to chuckle.

"No," he said, and she began to smile before he continued, "there are two. It was Mr. Sirius Black that brought you in." Hermione's thoughts were reeling, if Sirius was a student, then there was no way that this was normal.

'He must be playing a trick on me,' she thought, but when she looked back at him, she was once again struck by the differences in who was sitting before her, and who she remembered, 'Or not. Oh no,' Hermione's eyes widened, 'I'm in the past. Maybe I can change things,' Hermione began to smile as she thought of that; she would love to help Harry have a better life.

"You may not believe what I have to say, sir," Hermione said, looking down at her hands, and missing the look of pleasure that Dumbledore gave, she trusted him, maybe enough to learn details of the future.

"Go on," he encouraged, had he been sitting, he would have been on the edge of his chair.

"Well," Hermione began to tell Dumbledore what she knew that had happened.

Severus Snape was cursing his bad luck that had caused him to run into Sirius Black when he was in a bad mood. Sirius had cursed Snape's hair to turn red and gold, and now Snape had to go to the hospital wing to get Madam Pomfrey to fix it.

"So now I'm twenty years in the past," he heard a voice say. Snape's eyes widened, who had timetraveled, and how had they traveled so far. From what he knew, the Ministry of Magic was just beginning to test the possibility of traveling a few hours back.

"Hmm," he heard Dumbledore reply, "Interesting," then he raised his voice just little, "You may come in now, Mr. Snape." Inside Dumbledore was jumping for joy; Snape was an exemplary Slytherin. 'Yes,' Dumbledore thought, 'I can use him make sure she is on my side.' Dumbledore decided to see what he could get from this girl's mind about his future rule. To his surprise, he met Occlumency walls. Dumbledore was shocked, he had never met anyone who could successfully erect an Occlumency wall, and hold it against him. 'She must be extremely powerful,' he thought, 'I must get her on my side.' While he was thinking, he missed Hermione glance at Snape, and confirm her suspicions that he wasn't the one attacking her.

"What am I going to do, Professor?" Hermione wanted to distract Dumbledore for he did something else that she wouldn't know how to react to.

"You will go to Hogwarts," he was irritated that he had interrupted his thoughts, but wanted her to help him more, "and I will try to find a way for you to get back to your time." Dumbledore chuckled inwardly, he already knew how to send her back, but first he intended to get the knowledge he wanted, and only then would he send her back.

"What will we tell people about my appearance near the end of the school year?" She was honestly curious about what Dumbledore would think of, even if she no longer trusted him. Suddenly, there was an owl at the window, and all three of them turned to see it. Dumbledore removed the letter, and read it before walking back over to Severus and Hermione.

"It seems we have the answer to our questions," Hermione and Severus both looked confused by this statement, so Dumbledore clarified, "I am sorry to say that your parents are no longer among us, Severus," Severus' eyes widened, giving away his shock, and his mouth dropped open, but only a little.

"What on earth does that have to do with me?" Hermione asked. She felt bad for Snape, and wondered if this was part of what made him turn bad later in life, but couldn't feel too much remorse when she hadn't known them.

"You will be known as Severus' sister," Dumbledore's eyes where twinkling in the way that they always did when he was excited for some reason, "We will say that you were taught at home by your mother, and upon her death, you came to Hogwarts." Severus didn't say anything; he was still in minor shock from the death of his parents, not that he would miss his father at all.

"Sir? But I don't look anything like Severus," Hermione pointed out, this was not how she had expected anything to happen when she had gone to the Room of Requirement to work out her frustration.

"You look enough like his father, and have some of the features of your grandmother that it should be sufficient to explain anything else as being part of your muggle genetics," Dumbledore fought to keep the sneer from his voice as he said muggle, he truly despised them and found them filthy. Not giving them any time to protest, Dumbledore began walking towards the door, "Feel better Miss Snape." It took Hermione a few moments after he had left to realize that he was talking to her.

Seeing that Severus still hadn't moved, Hermione got up and walked over to him. She knew from her time that Snape wasn't a touchy feely person, but Hermione wanted to comfort him. She wrapped her arms around her 'big brother' and hooped he wouldn't do anything too drastic. To her surprise, after a few moments of standing awkwardly stiff, Snape hesitantly wrapped his arms around Hermione and relaxed.

"I'm sorry," Hermione whispered.

"It's alright," Snape replied as he pulled away to look at her, "You had nothing to do with it."

"Won't you miss them?" Hermione questioned. A dark look crossed Snape's face, and Hermione wondered what that was about.

"My mother, I suppose, but not my father." Hermione wanted to ask why, but knew better from the look on his face, it was the look he wore when Neville had explode yet another cauldron.

"We should get to know each other better if we are siblings," Hermione said, leading Severus towards her hospital bed. She filed away what little information she now knew about Severus' father, and decided to leave it be for now.

Severus and Hermione had found that, not only did they have a lot in common, but they also got along quite well.

"Where will we stay during the summer?" Hermione asked suddenly. She had been wondering for a while, but had just worked up the courage to actually ask.

"I don't know," Severus answered, and worried look on his face.

"Could we go stay at a friend's house?" Hermione wanted to stay with Remus or Sirius, but she doubted that would be possible, so she decided that at least Severus could be comfortable with where they stayed.

"We can't," Severus muttered as he looked down at his hands.

"Why not?" Hermione frowned, that was one answer that she hadn't thought about, but probably should have expected coming from Severus Snape.

"I made my one friend an enemy," Severus said it softly, but Hermione heard. She wondered if this had anything to do with the scene that Harry had mentioned briefly to her and Ron. As she waited patiently, Hermione reached over and gave her 'brother's' hand an encouraging squeeze. Severus took a deep breath before continuing, "Lily was my best and only friend," Hermione now knew that he was talking about Harry's mother, and was beginning to see part of the man behind her Potions Professor, "We grew up in the same neighborhood, and I taught her about magic. Once we came to Hogwarts, we were Sorted into different Houses, but remained friends. No one liked our friendship, but Lily insisted on being my friend anyways. Just last week, I had just been humiliated before most of the school, and Lily stepped in before I could be humiliated more. However, my pride wouldn't let me accept help from anyone, not even Lily," Hermione could see the regret on Severus' face, and waited as he paused to swallow. The next sentence was said in an almost silent whisper, "I called her a Mudblood." As offensive as Hermione found the term, she could see that Severus regretted his actions more than anyone would have expected.

"I'm sure that if you explain the whole situation to her, and tell her that you are sorry, she will forgive you," Hermione rubbed Severus' back as she suggested this, hoping that they would make up.

"I'll try," was all Severus would say before silence overcame the infirmary again.
