Harry Potter x Supernatural crossover, because my account is new and I need to do something to get over the finale.

Neither franchise belongs to me, I don't own any of the characters, blah blah blah

Warning: not beta read! I don't have a beta reader yet, so if anyone would like to volunteer that would be great.

Summary: Dean and Sam are offered a job at Hogwarts, and having nothing better to do, they accept and promptly send the student gossip wheel going faster than it has in years-or at least, since Harry's last 'scandal'. Takes place in third year. Just so you know, I've moved up the Harry Potter timeline so that Harry is now born sometime around '87, placing this story in 2011 around the time of Cas vs. Raphael and Cas dealing with Crowley

Chapter One- A Surprise For Hogwarts [2011]

Their new Defense Against the Dark Arts teachers were insane.

Seriously, who knew off the top of their head what a Wendigo was, or get rid of a ghost? Apparently the Winchesters, who were famous enough among the Hogwarts ghosts that none of them dared to go near the brothers. Even Peeves avoided them, which was something in of itself.

Dumbledore had introduced them at the beginning of the year, saying that they were a special branch of American Aurors who specialized in magical creatures. Well, not only were they crazy, but Harry had yet to see either of them do a speck of actual magic. He was beginning to wonder whether or not they were actually magical, but that didn't make sense because if they were Muggles, neither of them would be able to see the castle, much less teach there.

Still, what kind of lessons were these? Their first lesson of the year, Gryffindor and Slytherin, highlighted the differences in the countries' creatures, werewolves and vampires in particular. The taller one thought that magical ghosts might have more control over themselves, but his brother apparently disagreed. Either way, the ghosts avoided the Winchesters for all the were worth.

Three weeks after Halloween, the Winchesters vanished.

In their place was a small, skinny man who acted as a substitute teacher and told them to call him Garth "Since I prob'ly won't be here for long, anyway." He had a drawling accent and looked like a strong wind might knock him over, but a story started going around that he'd come across a group of Slytherins harassing a Ravenclaw and tossed them all to the ground in seconds. Said Ravenclaw, who was named Luna Lovegood, spent lots of time with him discussing who-knows-what.

When he left and the Winchesters returned [after another two weeks, with cuts and bruises that they refused to talk about, and a strange, jumpy new attitude for the taller one] she told them something that startled them so badly they kept watch on her out of the corners of their eyes for months.

The shorter one had also stopped sitting at his desk, and Harry had walked into class one day with several other Gryffindors to see him locking shut a drawer in it. He wondered what he kept in the drawer, and why he kept it if it was so painful that he didn't want to be near the desk anymore.

One day, they invited Luna back into their office, and she stayed for an hour and came out as happy as she'd been after her talks with Garth. Shortly after that, several fifth-year Ravenclaws were docked points for an unknown reason. Whatever it was, it lost them so many points that they put Ravenclaw last.

They left again, only a month after their previous absence. This time, their substitute was an older man named Bobby Singer who took no crap and had everyone wishing for the brothers to come back, because at least they were a little more easygoing.

The Winchesters eventually came back, and once again no one ever found out what happened. The shorter started using his desk again, and his brother kept watching him carefully, like he thought the shorter might explode at any moment.

Hermione kept griping about how Dumbledore shouldn't have hired them of they were going to keep disappearing at random times.

The Winchester's lessons didn't get any less strange after their absence. If anything, they got weirder. While Harry's year was still on tulpas [a sort of creature whose life depended on how many people believed in it], supposedly the sixth and seventh years were learning about demons and hellhounds. No one knew where the Winchesters got their information, and it soon became widespread 'fact' that they had learned it all firsthand, and that was why Dumbledore had hired them.

Harry didn't believe it. How could anyone have survived contact with all of those creatures?

He only started to believe it when the taller one burst into the Shrieking Shack wielding a gun [Ron had no idea what it was, and only panicked later when Hermione explained it to him] and had Sirius against the floor before Hermione could disarm them. Even so, it took half an hour to convince him that Sirius was telling the truth, and that was only because for some reason he was carrying Veritaserum. That, and the appearance of Peter Pettigrew. He said that he figured no one who had nothing to hide would pretend to be a pet for twelve years. Once they had won him over enough that he stopped trying to kill Sirius, Ron asked where his brother had gone. Dean threatened him with his gun and refused to answer. Hermione just wanted to know where they had gotten Veritaserum.

[Harry would later be told the true story about the Veritaserum, about how really Dean was bored and neither of the Winchesters liked Snape so they bribed Peeves with immunity to distract him and raided his office. The Veritaserum had been labeled truth potion, and the brothers took every vial he had.].

Dementors had accosted them while walking across the grounds back to the castle, and all of them had nearly been kissed until a huge patronus leaped out of nowhere. Dean and Harry were struggling to hold on to consciousness when Dumbledore arrived, and brokenly told the story of his innocence. Luckily, whatever they'd tied up Wormtail with had kept him from escaping.

Third year ended with a bang, and Harry was heading off to the Dursley's with the hope that Sirius would be cleared in time for him to go live with his godfather-anywhere was better than the Dursleys.

He couldn't help wondering what would happen to the Winchesters.
