Dean was leaning casually on a fence when he saw the first students for his class begin to funnel out of the castle and down towards where he was standing. Setting up this lesson had been a bit more difficult than he had expected, the subject of today's lesson was much harder to find than he had expected it would be in this world. On the other hand he had inadvertently come across quite a few other potential lesson subjects when he had been traipsing around the Forbidden Forest. "Morning, Professor!" Oliver Wood said eagerly, thrusting his hand out and shaking Dean's a bit manically. "I'm assuming that the Weasley twins haven't been causing you trouble?"

"Uh, you guys are my first class." Dean said, extracting his hand from Oliver's death grip. "Kinda hard to cause trouble when I haven't seen them yet."

"You clearly don't know them very well," Oliver said darkly. Dean made a mental note to keep an even closer eye on those two.

Dean stepped away from Oliver and clapped his hands together loudly. "Alright, can everyone hear me?" He said loudly. He waited for a general chorus of assent from the students and rubbed his hands together in anticipation. "Alright, everyone follow me into the Forest."

"The Forest?" One of the Ravenclaw students asked incredulously. "It's dangerous in there!"

"Mate, that's bloody Dean Winchester!" Another student, a Hufflepuff this time, sniggered. "I think he can keep us safe."

"He's not wrong," Dean said in his best teacher-voice, "Besides, we aren't going to go too far. They just don't like to be caught in the open, makes em nervous."

"What, exactly, are 'they'?" A Slytherin asked warily, eyes narrowed.

"If you guys shut up and follow me you will see, won't you?" Dean asked, his patience running thin. He hopped the fence and motioned for the students to follow suit. Granted, it was easier for him as he was in his customary flannel and jeans. Robes seemed to make the leap a bit more difficult as several stumbled and fell. He made a mental note to have them meet by the entrance of the fence next time.

True to his word he did not bring them too deep into the Forbidden Forest, stopping after only about a hundred yards. He had led them to a beautiful clearing of green grass and a small pond in the center. "Now, be careful when you approach them," Dean told them in a low voice. "Ladies, you head in first, they seem to prefer females from what I can tell."

The girls followed his instruction, stepping warily into the clearing and making their way to the center. After a few moments a collective, "Ooh!" of delight went up from the girls. Walking into the clearing, was a beautiful pure white horse with a stunning silver horn protruding from its forehead. The unicorn, after hesitating for the briefest of moments, allowed itself to be petted and rubbed by the girls. They all cooed to the horse as the guys looked on wistfully, almost like they were waiting for Dean to give them the go ahead. He motioned for them to wait a few moments, shooting them a reassuring smile. After a minute passed by more unicorns began to enter the clearing, evidently reassured that they were in no danger. Once the unicorns were all grazing peacefully, Dean allowed the male students to begin to filter onto the field. "Be slow, unicorns have an instinctive mistrust of dudes," He cautioned them.

Once he was certain that they weren't going to do something stupid he moved to the edge of the clearing and watched. He had always preferred being hands-on after all, even when he Hunted with Sam. The way he saw it, his lessons should be much the same. First-hand experience was always better than learning from a book. Dean knew from many past experiences that what was written in books could easily be wrong. He felt something nudge his leg and glanced down, expecting to see a bowtruckle hanging from his leg or perhaps a fairy. Instead he was surprised to see a golden-furred unicorn standing about navel-height. The baby unicorn nudged his side again and Dean ran a hand down its mane, smiling at the little one. "Hey there," he said softly, "What are you doing away from your mom?"

"Ooh, Professor!" One of the students, a Ravenclaw, exclaimed in delight. He moved forward towards the professor, one hand extended at the baby. The baby snorted when the student came close and moved to stand behind Dean. The disappointment on the student's face was evident when he saw that he was not going to be able to pet the unicorn foal. "Aww, man."

"Sorry, unicorns are really particular about who they let close," Dean offered. "That one by the pond seemed to be getting along well with you, why don't you go ahead and spend some more time with it?"

"Yes, professor," the Ravenclaw said glumly.

Once he had gone the foal bumped Dean's leg again with its forehead and Dean smiled ruefully. "Say, Professor," Oliver said, striding slowly up to him. Once he was within a few feet he lowered his voice and glanced over his shoulders. "We're having practice tonight, we really need your help if we are going to have a shot at the Cup."

"Sure, I don't mind helping out." Dean smiled at him, not a single clue of what he was getting himself into.

Back in the castle, Castiel was ten minutes late to his class when he finally walked through the door. The students had been congregating around a table, talking about something or other when he arrived. Upon noticing him they quickly took their seats and waited as Castiel made his way to the front of the room. Though he appeared outwardly calm, or at least he hoped he did, Castiel was racking his brains for some sort of lesson plan. Muggle Studies seemed like a massively intricate subject as it dealt with all the peculiarities and habits that normal humans went about.

"Erm, good morning class," Castiel began in uncertain tones. His best idea was one that he could attribute thanks to Sam for. Put simply, it was letting the person he was speaking to direct the conversation without the realizing they were doing so. "As I am unfamiliar with what you have thus far been taught, I thought it best for you to tell me what you wish to cover this year."

This seemed to somewhat surprise the students. "Professor, are you sure?" One asked, uncertainly. "I mean, you are the one who-."

"I am very well aware of what I have done," Cas lied. "But in my experience I have found that hu-… that people learn better when it is relevant to subjects that they are interested in."

To this the students had nothing to say. One tentatively raised her hand and Castiel nodded to her, a feeling of gratefulness washing through him. "Professor, why do muggles dress so differently?"

"That is an excellent question," Castiel said. "You see, Muggles often dress to their occupation. However, there are several occupation which may be something of a misnomer. Strippers, for instance, may often dress in apparel that would be suited for another occupation, such as a firefighter or perhaps a police officer."

"Professor, what's a stripper?" Another student asked, evidently unfamiliar with the term.

"And that should be good enough for class today," Sam said confidently. "Practice your stunning spells as homework for next class and give me a small essay on the concept behind stunning spells to be turned in next class."

The students departed and Sam took a seat at the desk at the front of the class. He left the desks on the outskirts of the room, intending for the next class to be very similar to this one. He was mildly surprised when he saw Lupin enter the classroom. "Remus," Sam said, rising and flicking his wand to summon a chair. "What's up?"

"It is our joint class," Lupin said uncertainly, pulling out a piece of parchment and then nodding as he confirmed the statement. "I assumed that was why you are here, this is the designated classroom after all."

"Of course," Sam said, "Sorry, I had forgotten. Did you still want to have them go over defensive spells?"

"As a first lesson I had thought that such an idea would be appropriate," Remus nodded. A coughing fit racked his body and Sam winced sympathetically once it had ended. "Forgive me, my health is questionable on the best of days."

"Totally understand," Sam nodded. A thought occurred to him and Sam voiced it before he could think the wiser of it. "Has the protection around Harry Potter been increased?"

"Protection around Harry Potter?" Remus asked, one eyebrow raising. "Whatever for?"

"Remus, I am a Dark Wizard catcher," Sam said, allowing his voice to fill with confidence. "It wasn't difficult for me to discover the shared past James Potter and Sirius Black share. The one you share with them, I might add."

This revelation seemed to have an odd effect on Remus, as he went even paler than normal. "H-how did you come across this information?"

"Sorry, my sources prefer to remain anonymous," Not to mention J.K. Rowling doesn't even exist here. "Sorry, I didn't mean to surprise you with any of this. I just want to be sure that all possible defensive measures are in place."

"Sam, the conversation we are about to have, well, I would prefer that it stay between us," Remus said, glancing over his shoulder.

"Anything you say to me will be confidential," Sam assured him.

"Very good. I am going to tell you exactly why Sirius Black was behind bars, the story that very very few people are aware of."
