By the next day without his boyfriend, Kurt was feeling all the symptoms of a broken heart. His side felt cold without Blaine walking along with him, his hand felt empty without Blaine's fingers intertwined with his.

"Every time I look at him, I get these pains in my chest," Kurt said. Tina and Rachel nodded sympathetically from their place on either side of him, "I can't eat. I can't sleep. I have to get him back, I can't live like this anymore!" Kurt sighed dramatically, his life full of ennui.

"We're going to figure something out," Tina said.

"Like hell you are," Santana appeared out of nowhere, "Look, Kurt, I feel bad for you, but you screwed up. I saw Trouty Mouth and the hobbit sucking face in the parking lot yesterday. Which isn't an exaggeration; my boy's lips are the size of Blaine's entire head."

"They were kissing?" Kurt said. Santana nodded and stalked off, hips swishing back and forth in her cheerio uniform, "That's it. My romantic life is reduced to watching the love of my life swap spit with Blonde Bieber."

"Oh, come on, Kurt, I'm sure there must be some misunderstanding," Rachel said. She was well acquainted with the troubles of ennui and would have done anything at that moment to make Kurt feel better. "Maybe... maybe Blaine tripped!"

"Blaine tripped."

"Perhaps."

"Onto Sam Evans' mouth."

"He does have a large mouth," Rachel said meekly. Kurt sighed heavily and rolled his eyes, "Look, Kurt, you cannot give up. You just need to walk up to him and say, 'Blaine Joseph Anderson. I am desperately in love with you, and if you had half a brain, you would take me back this instant!'" Kurt smiled humorlessly.

"Come on, Kurt," Tina said, "I can't stand seeing you depressed like this. You need to do something to cheer you up."

But Kurt had no interest in being cheered up. At the moment, he felt all the pangs of making the worst mistake of his young life, and he was content to wallow in it. The only bright moment of that day was walking into Glee and seeing Blaine sandwiched between Quinn Fabray and Sugar Motta, while Sam was shuffled off to Quinn's other side. Of course, Sugar had a bit of a crush on Blaine as well, but Kurt was convinced he had nothing to fear from her.

Blaine and Kurt locked eyes as Kurt went to sit down by Mercedes. Blaine sent Kurt a small smile, which Kurt tried to return through the stabbing pain in his heart.

Within minutes of the class beginning, Sugar Motta's hand was stabbing the air. "Alright, everyone. As you may know, the final installment of Harry Potter came out this summer. Now, I can't stand to watch movies with people that I haven't approved, so I got Daddy to buy out Lima Cinema for a private viewing of the movie!"

The excited murmurs filled the room, but no one was as excited as Blaine. "Oh my gosh, yes." He squealed as Sugar took her seat next to him, "I am so there. My dad and I dress up for every premiere. I'm always Harry Potter, and my dad picks a different character for each movie. Last year he was Snape; it was hilarious."

"What a great idea!" Sugar said, "Okay, everybody, change of plans. You all have to dress up as a character! Blaine, you can be Harry, of course..."

It was right around then that Kurt had an idea.

The days leading up to the party were feverish; Kurt carefully sewing and picking and choosing the composite pieces. The night of the party, Kurt spent an hour preparing. His vanity had a picture of Blaine on it, smiling in that heart-breakingly earnest way of his; and Kurt kissed it tenderly as he finished putting on his costume. He stared at himself in the mirror, thanking the gods of fashion that glee club was the only group invited. "I'm doing this for you, Blaine."

He met Finn and Rachel in the hallway. Rachel was dressed as Hermione Granger; her dark hair rumpled up in excess and a stack of books under her arm. Finn was standing next to her as Ron, a short red wig on his head and a store bought Griffindor uniform hanging from his shoulders. They both stared at Kurt, but neither of them said a word.

The walk into the theater was the most risky part; Kurt tried not to make eye contact, staring at the bright red and gold leggings he was wearing. He finally made it, and glanced around, taking in the costumes everyone had chosen to wear.

"I'm Lavender Brown," Tina explained in a tired voice.

"Racist," said Mike, standing behind her. He had shared his costume with Artie; they were standing back to back with their costume draping down to cover Artie.

"We're Voldemort and Quirrell, yo," Artie said, adjusting his turban.

Brittany was walking around with multicolored glasses and a bottle-cap necklace, though the dreamy expression on her face said 'Luna Lovegood' much more loudly than her outfit. She was linking pinkies with Santana, who had hair even more wild than Rachel's and a torn up black dress as Bellatrix Lestrange. Mercedes looked nothing short of fabulous in her Griffindor Quidditch uniform as Angelina Johnson. Rory was dressed as Neville, "I just think it's kinda cool that he started out a loser and then became all badass, you know?"

Lauren Zizes had crashed the party with a tea-cozy on her head, daring anyone to mess with her Dobby costume, and Puck was walking around in a pink dress, claiming that Dolores Umbridge was the biggest badass of them all.

"Hi, Kurt!" Sugar said, jumping in front of him. "Can you tell who I am?"

Kurt honestly didn't care who she was; he was much too busy scanning the crowd for Blaine. "Ummm... Hermione."

"No, silly. I'm Cho Chang, y'all!"

"Oh, dear," It was then that Kurt spotted his love, "I have to go, okay?"

Kurt found Blaine with his back turned to them, caught between a Quinn who was wearing the cool blue uniform of Beauxbatons a la Fleur Delacour, and Sam who had his hair slicked back in a cool impersonation of Draco Malfoy. Blaine's laugh echoed over to him, and Kurt, who had seen the Harry costume before, could just picture him. He'd be adorable, all wild hair and cute little glasses and hand drawn scar. Kurt took in a deep breath and walked toward them confidently, "Hey!"

The three of them turned around and froze. Blaine's gorgeous eyes widened behind his glasses.

"Kurt," Blaine said, in a tone that sounded like he had been hit over the head with a hammer, "You dressed up as..."

Kurt threw back his head - which had twice the effect when covered by a red wig - and stared at Sam.

"Ginny Weasley, at your service."
