A/N: Originally started writing this for Hunbastian Week, Day five (Crossover/AU) but I think I'm gonna rock this fic like a hooker pole. It's gonna be awesome! What you need to know: Hogwarts AU, Huntbastian, Klaine, Niff. Enjoy!

Hunter Clarington shined his prefect's badge and pinned it to his robes. He was glad he'd gotten picked as prefect over a lot of the riff-raff they let in Slytherin House these day. The Claringtons had all been in Slytherin for centuries, pureblood family and such.

"Hey, Hunter!" Ah, Sebastian Smythe, fifth year like Hunter, probably upset he hadn't gotten the badge. "Oh, goodie, you got one too!" Sebastian exclaimed. A prefect's badge gleamed next to the Ravenclaw crest on Sebastian's robes. Though they were in different houses, they'd become very good friends, in fact they were the leaders of their posse, well, mostly. Wes Montgomery, Ravenclaw, seventh year and now Head Boy, was the actual leader of their club, the Warblers, basically Wizard Show Choir. The Warblers were a very respected and exclusive club on campus, accepting only the brightest and most talented wizards. The Warblers cross-sectioned all the houses, bringing everyone together through mutual love and respect for music.

Among the other Warblers were Gryffindors Nick Duval and Jeff Sterling; Hufflepuffs Trent Nixion and Blaine Anderson; Ravenclaws Kurt Hummel and David Thompson; and Slytherin Thad Harwood. They were all fifth years and had been tight since their first year when they'd been hand-picked for the Warblers by the then-captain (Not Wes).

Hunter was pleased to see Nick and Trent had gotten the badges as well. How Nick managed to get the badge was beyond him, though, as Nick and Jeff were the biggest troublemakers at Hogwarts since the Weasley twins.

But that was two years ago.

Now Hunter Clarington shined his Head Boy badge, incredibly smug and pinned it next to his Slytherin logo. He stowed his cat and trunk carefully, cooing farewell to Mr. Puss, and walked down the train to find the rest of his posse.

"Well, well, well, if it isn't Hunter Clarington." The smirk was evident even in his voice. Prefect, Quidditch Captain, and now Head Boy, too. How much did it take to pay off the headmaster this time?"

"Sebastian Smythe," Hunter replied, coolly. "For your information, the headmaster thought I was the best man for the job, without father's money. What's the matter, upset your mommy didn't have the galleons to buy you the spot, or still bitter about last Quidditch season?"

"I'd watch it if I were you, Clarington," Sebastian warned.

"Or what?" Hunter laughed.

"Or you just may find yourself… falling… from … grace…" Sebastian said simply.

Maybe it would be relevant to mention Sebastian and Hunter had had a falling out at the very beginning of sixth year – with Wes gone, the Captain of the Warblers spot had opened. Wes had recommended Blaine for the spot, but Blaine had eventually declined, saying he wasn't the leader type. Sebastian and Hunter had duked it out for the position, and Hunter had eventually won, but not before Sebastian had aimed a curse at him. Sebastian had resigned his position later that day. Only Blaine had remained in contact with Sebastian, much to Kurt's chagrin (Kurt and Sebastian, despite being in the same house, had never gotten along).

"That's very intimidating," Hunter sassed. "Maybe if you knew how to back it up."

"Really?" Sebastian said. "Because while you were getting your Head Boy badge and a botox injection to the brain, I got two new badges." Hunter strode to Sebastian and examined his badges. The silver prefect's one, still there next to the Ravenclaw logo, and next to it… Quidditch Captain (that was predictable) and next to that… Warblers Captain?

"Excuse me, no, I am the Captain of the Warblers," Hunter said.

"Seems like the team disagreed," Sebastian said. Nick and Jeff appeared behind Sebastian, Blaine and Kurt behind them… "Play nicely, Hunter." Sebastian and his cronies disappeared into the train compartment. Hunter huffed and went passed their compartment, walking into the next one, where the rest of the Warblers were sitting.

"Uh-oh," Trent said.

"Sorry," Thad shrugged. "Sebastian made us."

"It's not that you were a terrible captain," Trent said.

"Yes, I was," Hunter admitted, folding his arms and taking the seat next to the window.

"Want to play exploding snap?" David asked, shuffling the cards.

"If Sebastian thinks he can just take my team away from me because I wouldn't–" Hunter stopped talking, staring around the cabin.

"Because you wouldn't what?" Trent asked.

"Nothing," Hunter said quickly. "Yes, I'll play." David dealt him into the game.

At some point during the last year, the hatred between Hunter and Sebastian had grown to unmanageable levels, and when they'd been paired as Potions partners… they realized why.

The tension between the two turned into sexual tension, which had turned into secret meetings in the Room of Requirement, which had turned into secret Hogsmeade visits via the secret exits Nick and Jeff had found in third year, and eventually, Sebastian had confessed how he really felt to Hunter… and Hunter had refused to say he felt the same way (even though it's possible that he did). He wouldn't let himself be that way, especially with a man, especially with a man as despicable as Sebastian Smythe.

They'd returned to hating each other.

This would be settled. And not in the nice way.

"Warblers Practice Room. 9:30. No witnesses," Hunter hissed to Sebastian as he passed him at the Welcome Feast. Sebastian glared at Hunter, wary of what might happen.

Sebastian showed up at the requested time, managing to somehow look nonchalant, lighting the candles with small flicks of his wand, then, because he was something of a pyromaniac, making the small flames dance because Hunter was late.

Hunter decided to show up a few minutes late on purpose, to put Sebastian on edge. When finally he did enter the Warblers room, there was Sebastian performing what looked to be a solo among the dancing flames.

"You are the strangest person I've ever had the misfortune to meet," Hunter interrupted. The flames all disappeared as Sebastian's concentration was shattered.

"As are you," Sebastian replied coolly. "What do you want?"

"Primarily, my team back," Hunter said.

"So, what, you want to duel me for it?" Sebastian asked. "Please. It's too easy."

"I demand satisfaction in Warbler tradition," Hunter said. Sebastian stared at him.

"Alright then," Sebastian said, waving his wand to conjure some background music for them. "Go ahead, save the best for last."

"Oh, I intend to, ladies first," Hunter said, indicating Sebastian should begin. Sebastian didn't take insults well. There was a flash and a bang, the music box disappeared, and Hunter was across the room, thrown against the wall. Hunter growled low and dug his wand out of his robes.

"No you don't," Sebastian snarled, and suddenly Hunter was hanging upside down in the air, his wand across the room. "Listen up and listen good. I am Captain of the Warblers now and I am tired of playing nice. In exchange for voting me Captain, the team has made me promise to keep you on, and I intend to, but if you try any more of your bullshit on me, you can bet you'll be finding yourself in the Hospital Wing, no memories of how you did." Hunter crumpled into a pile on the floor. "See you at practice."

Hell hath no fury like Sebastian Smythe scorned.

A/N: If you feel like my characterization of Sebastian and Hunter is backwards, it's okay, I do too. This will be multi-chaptered someday when I get around to it. It's gonna be so great!

Glossary of the glee characters and the houses I put them in, feel free to disagree and argue about it in a review:
Gryffindor: Nick, Jeff, Mercedes, Sam, Rory, Unique, Jake, Mike
Hufflepuff: Blaine, Trent, Finn, Artie, Sugar, Joe, Ryder
Ravenclaw: Kurt, Sebastian, David, Wes, Tina, Quinn, Marley
Slytherin: Hunter, Thad, Rachel, Puck, Santana, Brittany, Kitty
Honestly don't know how much the kids from the ND are going to be in this yet... But I thought I'd write it out just in case I change my mind.

Remember, not everyone in Slytherin is evil, and not all evil people are in Slytherin.
I'm not sure how Kurt ended up in Ravenclaw, I just thought he seemed like a Ravenclaw. Correct me if I'm wrong.
(My mom threatened to throw me out of the house for this, insisting Blaine needed to be in Gryffindor because he is quote, Harry Freaking Potter.)

Enjoy.
