A/N: Sorry about the delay. I have a ton of hard classes this year, so updating isn't at the top of my to-do list.

Chapter 9: Quarantine

The next morning at breakfast, Dumbledore told the school the basics of the Teen Titans. The entire team decided to keep their student names and garbs as Dumbledore didn't explain their powers. Dumbledore, though, did not tell the students of the school's lack of knowledge about the disease Dean had. A protective spell had been set up around Dean's bed in the hospital wing, and students were discouraged from going near there. Madame Pomfrey had talked to Raven about everything she knew about this new disease the day before, so Raven was able to attend all of her classes.

Raven had spent her morning in the shadows, avoiding questioning looks. The rest of the Titans basked in the glory given by the Gryffindors, Hufflepuffs, and Ravenclaws; but the Slytherins found it insulting that they had to learn alongside muggles.

After lunch, Raven had Transfiguration. The assignment was to turn a quill into a kangaroo, pointedly difficult due to the change in size. Much of the class had five inch kangaroos hopping around their desks. The class wasn't trying very hard, though. Instead their attentions were focused on Dick and Raven. Questions bombarded the Titans. Raven gave the questioners her trademark glare, sending them scurrying away to their kangaroos, while Dick answered most of the reasonable questions people asked. All of the students were preoccupied with the Titans. Well, that is, all of the students, except one. Sam Keller, a Ravenclaw friend of Dean's, sat slumped in his chair, poking his lifeless and hop-less quill with his wand. His cheeks were red, and he looked completely exhausted. Raven, completely ignoring the assignment, stared at the boy. He seemed sick to her; she could feel it. Finally, deciding something had to be done, Raven stood.

"Raven," Professor McGonagall snapped, "sit back down. Just because the whole school now knows about you doesn't mean I'll give you any special privileges." Raven ignored the teacher. She walked up behind the boy and placed her hands on his shoulders.

"Huh?" the boy questioned turning to look at her.

"Just relax," Raven said in an unusually soothing voice. The entire class watched as Raven once again gained the blue glow. The glow flowed to Sam, and he too closed his eyes.

After a moment, Raven stepped back from the boy. "We need to go to the hospital wing, right now. This boy's infected."

"What?" asked Sam, frightened by Raven's words.

Professor McGonagall stood. "Class, continue working. Raven, Sam, come with me." Dick watched as Raven and the sick boy exited the room with the teacher.

In the hospital wing, Madame Pomfrey put Sam in a hospital bed. "Well," she said, "now we know it's contagious." She sighed.

"How's Dean?" Raven asked.

"Not well. His fever is high. I'm going to have to ask Professor Snape for more Rednekar, the potion to reduce fevers. Especially now that someone else has it. Thankfully, St. Mungo's Hospital for Magical Maladies and Injuries is sending someone over with supplies tomorrow."

"Is there anything I can do?" Raven wanted to help. She had felt the illness. She wanted to fight it any way she could.

Madame Pomfrey looked up from Sam. "Do you know of healing potions?" Raven nodded, and Madame Pomfrey smiled. "Yes, you can help." Madame Pomfrey had Raven start by giving Dean and Sam each a dose of Rednekar.

In the meantime, Professor McGonagall went to each class and removed each student that looked remotely sick. She brought them to the hospital wing where Raven briefly examined each one. The students without the disease were free to return to their classes, but the students who had it had to stay in the hospital wing. After an hour, Madame Pomfrey had to magically expand the hospital wing and conjure more beds to accommodate the large number of students.

By the end of the day, Madame Pomfrey and Raven were both exhausted. Madame Pomfrey asked Raven to come back the next day and to look over some old medical books to see if this new disease might have evolved from an older one.

Raven entered the Gryffindor common room with a large stack of books. Immediately she was bombarded with questions. Harry and Hermione were able to break through the crowd and pull Raven to the corner where Dick and Ron were seated. "Thanks," said Raven.

"What's going on?" asked Dick.

"We don't know. I'm not going to anymore classes, though. I'm needed in the hospital wing." Raven leaned back in her chair and sighed. "I have fought everything from psychos to giant daemon lords, but I have never been more exhausted."

"What did you do?" asked Harry.

"I used a combination of potions and my powers to try to reduce the symptoms. I need to meditate." Raven stood and walked to the girl's dormitory with her stack of books.

The next morning, Raven immediately went to the hospital wing. Madame Pomfrey was extremely pleased to see her. "The man from St. Mungo's is here. We're to meet him in Dumbledore's office."

All of the teacher's were congregated in Dumbledore's office along with the healer from St. Mungos, otherwise known as Mr. McAllister. He was a tall, balding man with extremely dark skin and salt-and-pepper hair. Raven thought he must have been good-looking as a young man, though now his eyes showed sadness as if he had seen too much in his lifetime. He wore a white robe that was similar to a muggle lab coat.

Once everyone had squeezed into Dumbledore's office, Mr. McAllister began dishing out assignments. Professor Snape was to analyze samples of patients' blood to try and isolate the disease, be it virus or bacteria. Professor Sprout was to ignore all other projects and spend her time solely on growing plants that contribute to fever-reducing potions. The rest of the teachers were divided into groups. One group would aid Professor Snape, one would help Professor Sprout, another would make potions using the plants grown by the previously mentioned group, and the last would assist Madame Pomfrey in the hospital wing.

Mr. McAllister then turned to Raven. "I have heard much about you from Professor Dumbledore. Because I know nothing of your powers, I'm letting you choose which group you wish to aid."

Madame Pomfrey jumped next to Raven and latched onto her arm. "She can help me!" Madame Pomfrey insisted.

"Actually," said Raven working her arm loose from Madame Pomfrey's vice-like grip, "I don't work too well with people. I think I'll work with Professor Snape, but if you ever need me, I'll help you." Madame Pomfrey looked hurt, but nodded.

"Okay," said Mr. McAllister, once again addressing the group, "everyone must now get to work. Classes will be cancelled for this week so that everyone can begin making progress. One more thing, Hogwarts is now under quarantine. No student or teacher is allowed off Hogwarts' grounds, and no person from the outside is allowed to enter. All mail leaving the castle will be purified of all contaminants with a spell, so all mail will be monitored. If any student is found breaking these rules, make sure they are severely punished. That is all."

A/N: Sorry about the shortness of the chapter. The next one will be longer. I was originally going to have Harry go out with Ginny, but I'm contemplating having him go out with Raven. Review and tell me what you think.
