THE LIBRARY AT HOGWARTS

LATER THAT EVENING

Over dinner that night, Scully asked Snape to give her directions to the library, which he did. There was simply too much she didn't know about the wizarding world, and she felt that it put her at a disadvantage. Her thoughts were whirling and her eyes ached, so as soon as the meal was over, she switched over to her glasses and put her hair up in a ponytail, then headed toward the library. After consulting with the librarian, Madame Pince, she browsed the history section, and found the simplest books she could find. Scully reasoned that since she was learning everything from scratch, the thinnest books would be the ones to start with. She found a table and sat down to read. It was slow going, because all the names were new to her, but she was amazed at the discovery of an entire parallel history unfolding alongside her own! A few muggle occurrences had been influenced by wizard activity, although not directly, and even more surprisingly, there were several muggle events that were to change the course of wizard history.

The library was quiet and calm, punctuated by occasional whispers from the students. A few of them had smiled and greeted her. Just like her first impression at the dinner that first night, she thought they well mannered. Either that or just curious. She hoped to get to know more of them and maybe ask them some questions.

While she was studying, she heard the chair opposite her scrape and looked up to see a young witch accompanied by two young wizards. They looked at her quizzically and she gestured for them to sit down. The witch introduced herself as Hermione, then introduced her friends, Harry and Ron. Scully remembered seeing them in one of the potions classes. The girl had seemed to know what she was doing, but the boys didn't really stand out in any way. Except she remembered from their briefing that the brown haired boy was the baby who had survived the Voldemort attack so many years ago.

Hermione didn't seem to have any shyness. She talked about how she was born to muggle parents, and how a muggle aunt and uncle raised Harry since his parents had died, killed by You-Know-Who. Scully nodded compassionately in his direction, but she was struck by the way even the students used the common euphemism rather than Voldemort's name. The carnage he had caused must have been severe and appalling, even after all these years.

Hermione had a lot of questions about America and the FBI. Scully found that she did not need to be as circumspect when talking to these kids about her work as she normally would have been, because they were exposed every day to things she herself had never dreamed possible before being assigned to work with Mulder. And yet, she also became conscious that the differences between them were even wider than she had imagined before. There was the difference between muggles and magical people, for instance, but it was compounded by cultural differences. Her accent and her expressions started to sound peculiar to her own ears. Other students started drifting by and sitting down to listen or ask questions. Eventually, Hermione noticed the books Scully was studying.

"Histories of the wizarding world? Are they helpful?" Hermione asked.

"I suppose, but I don't have any background in any of this. I'm not always sure which events came before which other events."

At that point, Hermione demonstrated the personality that made her such a good student. She whipped out a pen and a rather long parchment from her bag, and started to write up a timeline. She worked at it while the other students talked to Scully, then handed it back to her to use as a reference. She also recommended two other books that Scully hadn't considered, but advised her against one of the ones Scully had selected. Scully was amused by Hermione's imperious tone, but grateful for the assistance.

One by one the students drifted away, and Scully resumed her studying. She had lost track of the time when a gentle hand on her shoulder made her jump. It was the librarian. 11:00 at night was closing time, but if Agent Scully would like to check these books out? Scully checked her books out, and walked slowly towards her guest room. There was a lot she wanted to run by Mulder. Maybe she could catch him awake.

Before she got to the guest quarters, she saw some light and heard noise coming from the staff room. Scully hesitated, then poked her head in and peered around. Mulder was in the middle of a group of people, listening to one of the faculty members hold forth. When Mulder saw Scully, he nodded and signaled to her with his drink. Scully nodded back, and looked for a place to sit down. She was thinking that most of the comfortable spots were taken when Dumbledore caught her eye. He was sitting with Snape, a little apart from the crowd. Scully eased herself into a cushioned chair next to them with a sigh, crossed her legs and pushed her glasses on top of her head.

"Professor Snape tells me you're doing research into our history," Dumbledore said to her.

"Yes, if there are no objections to my doing so," Scully replied. "Mme. Pince allowed me to check out these books. I was headed back to my room to read when I heard noise in here."

Dumbledore smiled at her. "Agent Scully, it's almost 11:30 at night. Pace yourself. There's no need to work yourself into exhaustion."

"But the more I know about your world, the more I'll be able to help. And you did say that we needed to be aware of the signs of You-Know-Who's activity."

Dumbledore chuckled. "If you had gone to school here, you would have been at the top of your class. Agent Mulder said you work yourself too hard."

She turned briefly to look at Mulder, still engrossed in the wizard's monologue and thoroughly enjoying himself. Scully thought that he seemed to fit in here better than she did, and certainly better than he did back home. She turned back to the two wizards and said, "I've been reading, but I still have a lot of questions. May I discuss some of these with you two?"

"Of course you may, but not right now. You need to relax a little. Go join your partner. We will continue this discussion at a later time."

Scully nodded to Dumbledore and Snape, then went to join the others in their conversation. Dumbledore turned to Snape, who watched her momentarily before looking down at his hands. "So, she knows?"

Snape replied, "She knows."

Dumbledore said, "Severus, I never required you to tell her. That was your own choice."

Snape nodded. After a few moments, he said, "Regardless, she is still willing to work with me." he almost had a tone of wonder in his voice.

" Severus, wizards aren't the only people who feel a sense of responsibility to their jobs. Agent Scully is a professional. She's been trained to do the job in front of her and not to cut and run at the first sign of danger."

Just as well she was trained to face danger, Snape thought. He wondered what would happen if You-Know-Who, in whatever form he was in right now, learned that there were muggles walking the halls of Hogwarts.
