Chapter 4:

The next morning Harry felt like he was back in his second year again, back when everyone thought he was Slytherin's Heir. Most of the students avoided his eye and conversations stopped when he got too close. And the more it happened the angrier he got. Ron and Hermione had noticed as well and were trying to distract him.

They sat down and began eating breakfast trying to speculate how long Hagrid would be missing when the Owls arrived delivering mail to the students. Hermione opened her copy of the Daily Prophet, and spent the rest of breakfast reading it to see if there were any more 'hints' about Harry or Dumbledore, luckily she found none. She was just putting the paper away when Professor McGonagall arrived with their schedules for the year.

"Look at today!" Ron groaned. "History of Magic, Double Potions, Divination and double Defense Against the Dark Arts. Binns, Snape, Trelawney, and the Winchesters all in one day. I wish Fred and George would hurry up and get those Skiving Snackboxes sorted…"

"Do mine ears deceive me?" Fred asked, as he and George sat down next to them. "Hogwarts Prefects surely don't wish to skive off lessons?"

"Look what we've got today," Ron said handing it to his brothers. "That's the worst Monday I've ever seen!"

Harry glanced down at his own schedule, he wasn't thrilled about the schedule but he was a little excited for the Double Defense Against the Dark Arts class.

History of Magic was just as boring as Harry remembered it being, so he was grateful when after a long lecture on Giant Wars, he was finally able to pack up and head to their next class. On the way to the dungeon the three friends speculated what their first potions class would be like, all agreeing that Snape would probably have them do a very complicated potion.

The class entered the Potions classroom quietly, and Harry sat between his friends at their usual table in the back.

Snape entered the room and after a brief look around left the door open before he went to his desk. "Settle down." He said although it wasn't necessary as his mere presence was enough to ensure the class's silence.

Snape looked up at the classroom door as the two Winchesters entered the room, closing the door behind them. The taller one waved politely before pulling the other towards two chairs that had appeared in the back of the class.

Harry shot confused looks at Ron and Hermione then at Snape who just nodded back and started his lesson.

"Before we begin today's lesson, I think it appropriate to remind you that next June you will be sitting an important examination, during which you will prove how much you have learned about the composition and use of magical potions. Moronic though some of this class undoubtedly are, I expect you to scrape by with an 'acceptable' in your O.W.L. or suffer my...displeasure."

His gaze lingered on Neville; who gulped.

"Today we will be mixing a potion that often comes up in the Ordinary Wizarding Level: the Drought of Peace, a potion to calm anxiety and soothe agitation. Be warned: if you are to heavy handed with the ingredients you will put the drinker into a heavy and sometimes irreversible sleep, so you will need to pay close attention to what you are doing.

"The ingredients " Snape flicked his wand, "Are on the board. You will find everything you need in the store cupboard. " He flicked his wand again and the said cupboard door sprang open.

"Awesome." Harry heard one of the Winchesters say. He turned to see the taller one elbowing the other.

The students all went in to gather their ingredients.

Snape waited until they had all started on their potions then went over to the two watching Professors.

Dean nodded to the Potions Master as he walked up to them.

"How are you enjoying my lesson so far?"

"Educational," Dean said with a smirk. Sam rolled his eyes at him.

"Do you mind if we look around the cupboard?" Sam asked.

"Not at all," Snape replied and followed the two men into it. They were both still wearing muggle clothing and Snape found it strangely uncomfortable to see flannel and leather jackets inside Hogwarts.

The two men walked around the room with interest. "Hey Sam," Dean said holding up a jar of pufferfish eyes. "I dare you to drink it."

"What are you five?"

Dean just chuckled and went back to looking at the ingredients.

"African Dream Root" Sam said looking at an unlabelled plant hanging from the ceiling. "Well now we know who to ask next time we need to walk in someone's dreams."

"Don't remind me." Dean said with a shudder. "That stuff is nasty." Dean turned to Snape and pointed at the small shelf that held his vials of blood.(Bat's blood, Salamander blood and Dragon's blood) "I'm surprised you don't have more of these."

Snape raised one eyebrow, "Why is that?"

"I'm use to seeing more blood in a pantry." Dean said with a smile. "Usually including: Dead Man's Blood, Lamb's Blood, Dog's Blood."

Snapes eyes got wider, before narrowing suspiciously. "And for what reason would I possibly keep Dead Man's blood in my 'pantry'."

"To slow down Vampires." Dean replied surprised. "I thought wizards knew that." he whispered to Sam.

"I...had not heard of that." Snape said.

"Well, I can see why Dumbledore asked us to teach here now." Sam said and Snape could see some of the tension disappear from the two men.

"I believe watching your class will also be...educational." Snape said with a slow smile, and the three Professors went back to the classroom.

Sam and Dean wandered the classroom looking with interest at the students making their potions, which seemed to be causing problems with the students because they started paying more attention to them then their potions. One boy with bright red hair who Dean vaguely remembered Dumbledore telling him was a Prefect named Ron, had caused his potion to spit green sparks.

"A light silver vapor should now be rising from your potion," called Snape with ten minutes left to go. Dean looked around the room and winced when he realized that only one student seemed to have gotten the potion right. Sam and Dean retreated to their chairs and observed from afar for the rest of the lesson.

When the lesson was over the three Professors went to lunch and Snape asked the two Muggle Professors more about the African Dream root and Deadman's blood.

"If you would like you can drop by our room later tonight. We usually keep a few vials of Deadman's blood on us if you would like to add some to your pantry." Sam told Snape as he passed the sheppard's pie to Dean.

"I think I would like that very much." Snape said, surprising himself.

"We'll see you then." Dean said with a wink, before devouring his lunch.

When the bell rang at the end of Divinations, Ron and Harry went back down the latter, Ron grumbling loudly.

"D'you realize how much homework we've got already? Binns set us a foot-and-a-half-long essay on giant wars, Snape wants a foot on the use of moonstones, and now we've got a month's dream diary from Trelawney! Fred and George weren't wrong about O.W.L. year, were they? Those Winchesters had better not give us any…"

When they entered the Defense Against the Dark Arts classroom they found the Winchesters standing at the teacher's desks talking with Professor Snape.

The class was quiet as it entered the room; Both Professor Winchesters were an unknown quantity and nobody knew yet how strict a disciplinarian they were likely to be.

When everyone had found a seat, including Snape who was watching as well from behind the professors desks, one of the Professors stepped forward.

"Hello. My name is Dean, that's my brother Sam." He said with a cheeky grin. "We will be teaching your Defense Against the Dark Arts class."

He paused when Hermione raised her hand. "Um.. Yes?"

"Is it true you're Muggles?" she asked.

The class broke out in excited whispers and from the shocked looks on the Slytherin faces, Nearly Headless Nick's revelation hadn't gotten passed the Gryffindor common room.

"Muggle...? Muggle?" Dean asked confused but Sam shrugged. He didn't know either.

"It means a person who is born of two non-magical parents and are incapable of doing magic themselves." Snape said

"Oh! Well then yes, yes we are." He said. He was about to continue but got interrupted again, this time by Draco Malfoy.

"How can you teach Defense Against the Dark Arts if you can't do Magic?!" he demanded indignantly.

The two Professors grinned at each other. "If that was what was required we would have died a long time ago." He paused for a second looking like he was going to continue that statement but decided against it.

"Then what qualifications do you have to be teaching this class?" Pansy Parkinson asked haughtily.

"Because we're Hunters." Dean said.

Snape flinched and his face turned white.

"What do you hunt? Deer?" Seamus Finnigan asked, confused.

"We usually hunt more dangerous game." Dean said. "Ghost being the most common. But we've run across a few werewolves, vampires, and demons in our time." Dean leaned closer and said in a fake whisper, "And every once in awhile, we hunt Witches."

The class looked at the two men in horror and Harry who had noticed Snape's reaction now knew why he had flinched.

Sam rolled his eyes. He placed his hand on Dean's shoulder and took over the lesson. "Did you have to?" He asked as Dean went to sit down.

Dean just shrugged.

"Dumbledore asked us to teach you our way of fighting, because it seems to be very different from what you're use to." Sam said but before he could get much further he was also interrupted.

"Demon's aren't real!" Draco said.

"Oh they're real all right, trust me."

"But that is for another lesson." Sam said looking pointedly at his brother. "Today we will be starting with the basics."

"When dealing with most spectral beings your best protection will be salt." Sam turned around and wrote salt on the board. "Luckily salt is usually easy to get." then he went over to his desk and pulled out a large container.

"I managed to get one of the House Ghosts to help us with this demonstration." Sam nodded at Professor Snape who stood up and opened the classroom door. The Bloody Baron entered and floated to the front of the classroom.

"Okay, there are a few ways to use salt to repel ghosts.

"The first is the salt circle. We use this as a base when we know a ghost is coming but don't know where they will attack." He then proceeded to pour a surprisingly good circle of salt on the floor around himself, then nodded to the Bloody Baron. The Baron advanced but when he reached the circle it looked as if he hit a brick wall.

"You can also use it to trap ghosts." he said, "This doesn't solve most problems when it comes to ghosts but it will hold them for a little while." He then went to making the circle around the Bloody Baron.

"Sorry." he told the ghost. The class watched as the Bloody Baron attempted to leave the circle, even trying to go through the ceiling, but he was trapped.

"An open circle doesn't work as you can see when I break the salt-line." Sam said, as he did so, and the Baron left the circle.

"Lastly you can protect an enclosed room by putting a salt line at all the doors and windows. But like the protective circle, if the salt line is broken they will be able to enter the room.

"These protective barriers are most useful for ghosts and demons. If you're facing a monster like a werewolf or a skinwalker they will be useless."

Sam stepped back to clean up the salt as Dean took over the lesson.

"Salt can also be used as a weapon." He said, as he bent over and grabbed a handful of salt from one of the protective circles before Sam could finish cleaning them.

"Ready?" He asked the Bloody Baron who nodded his consent.

Then to the shock of the whole class, Dean threw the salt at the Bloody Baron. Harry was confused until instead of passing through the Bloody Baron he shattered into dust.

The whole room gasped.

Dean dusted off his hands, and continued as if nothing weird had happened. "Throwing salt is useful but my favorite way to dispel ghosts is to shoot them."

He reached over his desk and pulled out his double barrel shotgun.

The room gasped again as the Bloody Baron flickered back into existence.

Dean broke open the shotgun and expelled two shotgun shells. "Normal rounds don't work on ghosts of course."

"These" he said holding them up, "are filled with rock salt.

"They'll hurt like hell if you get hit but they'll dispel a ghost for a little while."

Dean turned back towards the Bloody Baron, after reloading the gun. He made sure he was between the Baron and the students then aimed. After another nod of consent from the Baron, he fired the shotgun. Once again the Bloody Baron shattered into dust.

Dean emptied the shotgun and placed it back behind his desk.

"Why would we need to fight ghosts?" Draco asked confused.

The two Professors smirked at each other. "That," The taller one said, "Is your extra credit tonight. Ten house points will be awarded to the students who find the answer. And your homework will be to write half a foot essays on the properties and uses of Salt in defense. Which you can start on for the rest of this period."

After their Defense Against the Dark Arts class Harry stumbled across Professor Snape talking to Draco in an unused classroom. (Ron and Hermione had gone to a prefect meeting) He hid behind a tapestry of an empty grove, trying to listen in.

"...be careful this year." Snape said with a strange inflection in his voice. "If they truly are Hunters you must inform your father."

"But what are Hunters?" Draco asked confused.

"Your father will know." Professor Snape said cryptically before he swept out of the room.

The conversation played over and over in Harry's head until dinner where the Trio had met up again.

The Great Hall was filled with rumors about the Winchesters. Third, Fourth and Seventh years wouldn't have them until later this week, but they listened to the stories and added to them where they could.

"...and then he pulled out the gun." Dean Thomas told a large audience at the Gryffindor table, including some who were in the class. "I almost had a heart attack!"

Susan Bones was giggling in a group of Hufflepuffs. "...they're both so tall."

"...can't believe they hired Muggles to teach Defense Against the Dark Arts. When my Mother hears about this…" Blaise Zabini was saying to his own audience at the Slytherin table. Draco Malfoy was ignoring them, and seemed to be lost in thought.

The Ravenclaws were huddled together as they compared notes. "... planning on looking through books in the Library's Ghost section."

When dinner ended Harry pulled Ron and Hermione aside and told them about the conversation that he had overheard.

"But what are Hunters?" Hermione asked.

"I don't know but Snape said Lucius Malfoy would." Harry said.

"We could try asking my Dad." Ron said "He might know."

"Good idea. I'll owl Sirius as well. Can't help finding out more about them." They headed to the Owlry and after writing a note to Sirius and Mr. Weasley, they woke up Hedwig and Pigwidgeon who blinked at them sleepily while they tied the letters to their legs, then flew out the open window into the evening light.
