CHAPTER THIRTEEN
Trouble

"What are you doing here?" Santana asked sloppily, glaring at the boy who watched them with his perpetual smirk stuck on his face.

"I was in the mood to party," he shrugged. "So I followed the sound of shitty Broadway tunes and found the only losers in town who actually listen to this garbage."

Kurt squinted at him, taking a wobbly threatening foot forward. "You should leave."

"Why?" Sebastian asked, cocking his head to the side. "The party's just about to get started." Before Santana could complain, he plucked the drink out of her hand and downed it, wincing at the taste. "Yeah, I can truly say I haven't missed these."

"You've had it before?" Blaine blurted because he was drunk and well, impulse control stops becoming a thing when drunk.

Sebastian raised an eyebrow, looking down at Blaine who was still sprawled out on the floor. "Oh shortstop, you have no idea."

"Leave!" Kurt yelled, his voice pinching at the end.

"Oh don't get your knickers in a twist," Sebastian said sitting down next to Santana. "I won't be any trouble."

"Bullshit," Kurt spat, turning to face Blaine. He held out his hand and pulled the shorter boy to his feet, taking a moment to let Blaine steady himself so the room would stop spinning, before pulling him over to where Mercedes was just hopping off of the stage.

"Hey Kurtsie," she said with a smile, pinching his cheek before he smacked it off. "Oh no," she cried, looking at her hand in disbelief. "What's the matter?"

Kurt just pointed in the general direction of Sebastian before planting himself on the edge of the stage.

"Shit," she breathed, sobering up immediately, before making eye contact with Puck and beckoning him over.

Puck was shirtless and the belt of his jeans was gone, so they were riding low on his hips as he swaggered over. "Sup?' he slurred, a happy grin on his face. Mercedes pointed to Sebastian, and was about to say something before she realized she was talking to air. Puck was already marching over to the seated boy, a look of pure ire on his face.

"The hell you think you're doing here?" Puck asked, man handling Sebastian to his feet.

"Calm down," he said, patting Puck's hand. "I just came here to party."

"Well you're not invited," Puck hissed before roughly letting him go. "So get out of here."

Sebastian just brushed himself off. "I have it on good authority that you guys weren't raised by wolves, so where are your good manners? Your parents would be so ashamed."

Puck growled again, raising a steady fist. "I won't ask again. GET. OUT."

"Kurt," Sebastian called. "Please call off your little guard dog. We don't want things to get ugly now do we?"

The music was quieting down as everybody became aware of Sebastian's presence. Blaine felt the atmosphere shift from drunken happiness to focused anger and annoyance. Sebastian had a certain type of effect on people.

"Oh, no answer?" he fake pouted as the party goers moved in closer. "We don't really want a repeat of last time, do we?" he asked turning his attention back to Puck. "I know how much Kurtsie hates hospitals."

"What do you want?!" Kurt practically screeched, leaping up from his spot on the stage and over to the middle of the room.

"I know you have better things to do than party crash."

"I told you," Sebastian replied, gently placing his hand on top of Puck's fist and lowering it. "I just want a drink."

Santana and Quinn looked at each other before they both shrugged. "A drink it is," Quinn said calmly, bringing her red solo cup forward. "And no," she continued as he took the cup. "It's not Santana's Liver Buster."

He gave her a small gracious smile before taking a big gulp and taking a step back from Puck. "See?" he said to the group, "That's not too bad is it?"

"Okay," Rachel said taking a step forward. Sebastian raised his brow at her, surprised she hadn't fallen since she was always such a sloppy drunk. "You've had your d-drink," she stuttered out, crossing her arms. "Now go."

"Rude," he chided, pushing past her. "I don't even get to sing first?"

She snorted. "You're not worthy of s-stepping onto my stage."

He shrugged as he stepped onto it, taking hold of the microphone. "Too late."

Blaine looked up at Sebastian from his spot on the stage, and then back down at himself again, and then back to Sebastian. "Should I...should I move?" he asked uncertainly.

Sebastian smirked. "I think you should join me."

Blaine frowned and looked at all the party goes. Jeff, Quinn, Puck, Mercedes, Tina, Jake, and Sam were all shaking their heads and mouthing various forms of 'don't do it.' Santana and Rachel were nodding spastically, and Kurt looked so pissed off his face was turning red.

"I love it when he does that," Sebastian whispered into Blaine's ear. Blaine jumped and turned his head, his cheek slamming into Sebastian's mouth, which just puckered and kissed his cheek with enthusiasm. "Rawr," Sebastian growled in his ear. How had he gotten so close? "Any other time I'd be all game, but this really isn't a good time. Rain check?"

Blaine pushed himself up and backed away from the stage, wiping his cheek with disgust.

"I'll take that as a no," Sebastian said with a laugh. "Oh well, guess I'm going solo."

"No," Kurt said, stepping forward. "I'll sing with you."

Sebastian smiled a toothy grin. "Just like old times, eh?"

Kurt didn't even reply. Just walked onto the stage, taking the other microphone. "Crowd, choose a song," he said. "Let's get this over with."

"Me, me me me choose me!" Rachel yelled waving her hand in the air like she was at school. "I have the perfect song for you two!"

Kurt nodded his head, and she squealed running over to Artie (still not falling), and whispering her request in his ear. The boy chuckled, and typed something into his i-tunes before giving the nod to Kurt that everything was ready.

"Let's do this," he said into the microphone. Artie clicked play and a familiar tune wafted around them. Sebastian and Kurt rolled their eyes at the same time but Santana nodded and muttered "Perfect choice," to herself.

Sebastian turned to Kurt and smiled, "I guess I'll start," he said with a wink, before raising the microphone to his lips.

Once upon a time a few mistakes ago
I was in your sights, you got me alone
You found me, you found me, you found me

Kurt stepped forward and Sebastian moved back, giving Kurt the next part of the verse.

I guess you didn't care, and I guess I liked that
And when I fell hard you took a step back
Without me, without me, without me

And he's long gone when he's next to me
And I realize the blame is on me

Cause I knew you were trouble when you walked in
So shame on me now

Sebastian took over, standing next to Kurt.

Flew me to places I'd never been

Kurt took over, anger heavy in his tone.

'Til you put me down, oh

Together they sang;

I knew you were trouble when you walked in
So shame on me now
Flew me to places I'd never been
Now I'm lying on the cold hard ground
Oh, oh, trouble, trouble, trouble
Oh, oh, trouble, trouble, trouble

Kurt took the beginning of the next chorus, a million emotions flowing through him in a whirl too massive to even comprehend.

No apologies, he'll never see you cry
Pretend he doesn't know that he's the reason why
You're drowning, you're drowning, you're drowning

Sebastian sang the next part, and if he was glaring at Blaine nobody commented on it.

Now I heard you moved on from whispers on the street
A new notch in your belt is all I'll ever be
And now I see, now I see, now I see

Kurt turned to face Sebastian.

He was long gone when he met me
And I realize the joke is on me, yeah!

Sebastian met Kurt's gaze as they sang the chorus together; cool grass meeting an impossible colour, as they had a conversation they should have had years ago.

I knew you were trouble when you walked in
So shame on me now
Flew me to places I'd never been
'Til you put me down, oh
I knew you were trouble when you walked in
So shame on me now
Flew me to places I'd never been
Now I'm lying on the cold hard ground
Oh, oh, trouble, trouble, trouble
Oh, oh, trouble, trouble, trouble

Kurt moved into Sebastian's space as he sang the next two lines; hurt pouring off of him in tidal waves.

And the saddest fear comes creeping in
That you never loved me or her, or anyone, or anything, yeah

Sebastian shook his head as he joined in with Kurt for the last chorus, turning back to the crowd who watched them in near silence.

I knew you were trouble when you walked in
So shame on me now
Flew me to places I'd never been
'Til you put me down, oh
I knew you were trouble when you walked in (you were right there, you were right there)
So shame on me now
Flew me to places I'd never been
Now I'm lying on the cold hard ground
Oh, oh, trouble, trouble, trouble
Oh, oh, trouble, trouble, trouble

I knew you were trouble when you walked in
Trouble, trouble, trouble
I knew you were trouble when you walked in
Trouble, trouble, trouble

The music died down and turned into heated silence as Kurt glared at Sebastian.

"Holy shit," Blaine whispered, but in the silence of the room it echoed so that everyone could hear.

"Now leave," Kurt growled, finally tearing his eyes away from Sebastian. "Please."

Sebastian nodded, putting the microphone back in the holder and walking across the stage. He turned back to look at Kurt who had his arms crossed, but it looked more like he was wrapping his arms around himself.

Sebastian didn't say anything as he left, the bell ringing on the door as it closed, acting as his goodbye.
