"Hey." Blaine greeted cheerily as he opened his front door to Kurt "Ready to practise?" Blaine asked. As next week's show was titled as 'duet night' Kurt and Blaine took this as the perfect opportunity to see each other almost every day without it seeming weird to their significant others.


Kurt smiled at Blaine walking into his house "Where's Sebastian?" Kurt asked, although he didn't really care nor did he want to know.


"Work. Why'd you ask?" Blaine said offering to take Kurt's coat; Kurt accepted pulling off his coat, revealing his black and white striped top and dark blue jeans.


"No reason, I guess. So, what song do you want to sing?" Kurt asked crossing his arms, following Blaine into the living room.


"I was hoping that you would have an idea." Blaine smiled, sitting on the arm of the sofa.


"Well, what do you feel like singing?" Kurt asked, standing in front of Blaine.


Blaine just shrugged "You wouldn't think it would be this hard to think of a song to sing about." Kurt chuckled before furrowing his eyebrows again, trying to think of something to sing.


"I've always heard that it is highly effective to sing about emotions," Blaine suggested, "You know, to share how you feel with the world why really not sharing anything at all."


"I suppose that could work," Kurt said, although he knew he had to keep their feelings for each other secret for now, sometimes he just wished he could tell someone how he felt, and by singing was the perfect way to do so. "What song do you suggest?"


Blaine thought for a moment before answering "It's your love by Tim McGraw and Faith Hill?" Blaine said looking over at Kurt looking for any sign of approval or rejection.


"I guess." Kurt said, just shrugging.


"What's wrong, Kurt? You've been acting weird since you go here." Blaine asked, his bright expression dulling when he realised that something was worrying Kurt.


"I don't know," Kurt sighed in frustration, looking up at Blaine and relaxing his tensed body a little "Sebastian maybe, it's like, I don't know, I can't explain it."


"Then sing it." Blaine said hoping to try and understand where Kurt was coming from.


"O-okay." Kurt said thinking of the best song to describe his feelings before he began to sing.


________________________________________
"Wow." was all Blaine could say, "Kurt, we have to sing that for duet night." Blaine said taken back by the amount of emotion Kurt had behind that song.


Kurt blushed a little, keeping his vision glued to the floor "You don't think that it's pathetic?" Kurt asked, now standing in front of Blaine.


"Wha-, Kurt, no, that, that is amazing and a great way for you to finally stop bottling up some of that emotion and share your talent." Blaine smiled, more than impressed with Kurt.


Kurt laughed, resting his head on Blaine shoulder "I guess we have found something to sing at last." Kurt sighed, more contented now than before he started singing.


"Yep, we now just have to divide it into parts." Blaine smiled just as he heard a key enter the lock; Kurt took his head of Blaine's shoulder just before Sebastian walked into the room.


"Hey baby." Sebastian smirked walking in the room, usually he would have just went to the kitchen, but realising Kurt was there he decided to really rub his nose in it, pulling Blaine in for a short but heated kiss.


"How's rehearsing going?" Sebastian asked turning to smirk at Kurt.


Kurt let his gaze drop to the floor as all his muscles tensed restraining himself from just punching Sebastian in his overly smug face.


"Good, baby," Blaine forced a smile across his features "Just gotta decide who's singing what."


"That's good." Sebastian said to Blaine.


"You going to come and watch us perform next week?" Blaine asked, a sly look shortly possessing his feature before disguising it with his usual dashing smile.


"I wouldn't miss it for the world." Sebastian pulled Blaine in for one more heated kiss before making his way up the bathroom.


"Why'd you do that?" Kurt asked in hushed tones.


"Do what?" Blaine asked completely taken aback


"Invite him to our performance next week?" Kurt asked, gnawing on his bottom lip.


"So you get to tell him exactly what you think, and fuel your performance even more so." Blaine smiled proudly "Now, let's divide this song into parts."


________________________________________
Tonight was the night that the last week had been the run up to, tonight was duets night. Kurt was a little nervous, but he knew as soon as he saw Sebastian in the crowd it would just be the fuel to his fire and he would use it to the best of his advantage.


Kurt was happily day dreaming when a familiar voice brought him back to reality.


"Kurt." Blaine said happily, and a little surprised at how good Kurt looked tonight, he was wearing a pair of black jeans with a low hanging chain attached to the belt loops, a tight fitting 3 quarter length sleeved black top which was partially covered by a purple waist coat.


"Blaine," Kurt smiled widely before looking over at who Accompanied Blaine with a less pleased smile. "Sebastian." Sebastian smiled weakly.


Before the trio had time to start a conversation Kurt and Blaine were called by Drake, they were next on. Sebastian kissed Blaine quickly before turning his attention to Kurt and smiling smugly "Break a leg," He began to walk away from the pair allowing himself to mutter "Or two." before finding his seat within the performance hall.


________________________________________
Grace and Thea had just gotten off of the stage, the roaring of the crowd dying down as Blaine and Kurt walked onto the stage, the pair set up their microphone stands allowing the calming of the crowd to settle their nerves before the song began to play.


Kurt started singing in a low voice trying to single out Sebastian in the crowd of people that were packed into the performance hall that night, once he set eyes on him he allowed his emotions to take over to put across this message to him.


Hey old friend, thanks for callin'
It's good to know somebody cares
Yeah she's gone, but I don't feel like talkin'
It might be just too much to bear
To hear somebody say it stops hurting
Or to hear somebody say she ain't worth it


Kurt held onto the mic stand, his eyes closed and his body unwavering allowing his emotions to be the power behind his voice.


'Cause you don't know her like I do
You'll never understand
You don't know we've been through
That girl's my best friend
And there's no way you're gonna help me
She's the only one who can
No, you don't know how much I've got to lose
You don't know her like I do


Kurt opened his eyes now to see the look on Sebastian's face, Kurt was pleased with the disapproving look on Sebastian's face. The crowd was already swaying and cheering as Kurt sung encouraging Kurt to sing louder and more sincere than ever before. Blaine now began to sing.


I can't forget, I'm drowning in these memories
It fills my soul with all the little things
And I can't cope, it's like a death inside the family
It's like she stole my way to breathe
So don't try to tell me I'll stop hurting
And don't try to tell me she ain't worth it


Blaine, was looking over at Kurt the whole time. Blaine allowed his body to move along with the beat of the music, the crowd and his own feelings for Kurt being the power behind his own performance, his voice gravelly adding to the songs initial intensity.


Cause you don't know her like I do
You'll never understand
You don't know we've been through
That girl's my best friend
And there's no way you're gonna help me
She's the only one who can
No, you don't know how much I've got to lose
You don't know her like I do


Blaine took his mic out of its stand using his old Warbler moves as he danced his was around the stage, this making the energy of the room pick up more so than before, adding a new layer to his and Kurt's performance. Kurt began to sing again.


You don't know her like I do
You'll never understand
You don't know we've been through
That girl's my best friend
There's no way you're gonna help me
She's the only one who can
No, you don't know how much I've got to lose
No, you'll never know how much I've got to lose
You don't know her like I do


Kurt had now also taken his mic out of its stand standing at the front of the stage singing to the audience, Kurt singing to one person in particular. Blaine took the last part of the song.


Not like I do
Never understand
That girl's my best friend
That girl's my best friend
That girl's my best friend


The crowd roared at the end of the performance, Kurt and Blaine both bowing as they made their way off of stage; they hugged each other smiling, and still on their adrenaline highs.


"Now that was a good performance." Blaine smiled widely.


"That it was, did you see his face." Kurt laughed his breathing finally evening out.


"I know. I better go and get my stuff, text me later." Blaine said before rushing off to his dressing room.


________________________________________
The song ended, Sebastian wasn't stupid, and he knew that Kurt was singing that song to him about Blaine. Sebastian walked back stage; the place was near enough empty, apart from Kurt putting his things in his bag and the few others waiting for cabs to get home.


"Nice song." Sebastian said from behind Kurt, making him jump a little.


"Thanks, I thought so." Kurt said nonchalantly regaining his composure.


"I know you were singing to me, Kurt, About Blaine." Sebastian said through gritted teeth.


Kurt smiled to himself, getting his desired reaction, he turned to face Sebastian "Oh please," Kurt said coolly trying not to show how much he was enjoying Sebastian's reaction. "Get over yourself, it was just a song, something tells me you feel threatened by me." Kurt said allowing his feature to become stern and unforgiving.


Sebastian's usual smug mask slipped momentarily, telling Kurt all he needed to know "Back off Hummel. I'm watching you from now on." Sebastian all but growled before walking off to find his partner and drive home. Kurt waved at Sebastian as he left. Kurt smiled, satisfied.


________________________________________
Sebastian let himself into Blaine's dressing room smiling at his boyfriend "There you are. You were amazing." Sebastian smiled, almost immediately wrapping his arms around his boyfriend, one, to show Blaine his adoration for him but mostly so that Sebastian could prove to himself that he still had Blaine.


"I know. It was exhilarating." Blaine said pleased with himself allowing Sebastian to embrace him.


"Ready to go home?" Sebastian asked, knowing that Blaine would probably be tired after such a high-energy performance.


"Yeah." Blaine said yawning, following Sebastian out to the car to go home.


________________________________________
Kurt had gotten home and was ready to collapse from exhaustion, practically crawling up the stairs to his and Dave's bedroom he threw off his clothes haphazardly crawling into the covers of his and Dave's bed.


"How did it go?" Dave asked, wrapping an arm around a very sleep deprived and emotionally drained Kurt.


"Good, I'll tell you all about it in the morning, now, sleep." Kurt said before yawning and snuggling further down into the bed. Dave chuckled and agreed.


"Okay, Goodnight, Kurt." Dave said also allowing himself to drift off to sleep for the night.
