Blaine stood still in front of the New Directions gang as the opening notes started playing. He looked anywhere but Mercedes, knowing that she knew who this song was about. So maybe it was about his boyfr-Blaine sighed-EX boyfriend, Kurt who now attended NYADA with Rachel. If only Kurt could hear this, maybe it would show him that he is still the only one. Blaine took a deep breath as his queue arrived, and opened his mouth to sing.

You and I walk a fragile line

I have known it all this time

But I never thought I'd live to see it break

It's getting dark and it's all to quiet

And I can't trust anything now

And it's coming over you like it's all a big mistake.

Blaine felt his heart aching, and heard the emotion start to enter his voice. There was no way he was going to cry in front of these guys, it was not happening.

Oh, I'm holding my breath

Won't lose you again

Something made your eyes go cold

He got into the rhythm and brought a fist up to his chest as he belted out the chorus.

Come on, come on, don't leave me like this

I thought I had you figured out

Something's gone terribly wrong

You're all I wanted

Come on, come on, don't leave me like this

I thought I had you figured out

Can't breathe whenever you're gone

Can't turn back now, I'm haunted.

Blaine dared his first real look into his audience, and saw they all were feeling the song with him. Mercedes was who scared Blaine. She looked so upset, like she couldn't believe it had come to this. He couldn't pull his eyes away; he began singing the song, look right at Mercedes.

Stood there and watched you walk away

From everything we had

But I still mean every word I said to you

He would try to take my pain away

And he just might make me smile,

But the whole time, I'm wishing he was you instead

Blaine read the expression on Mercedes face made Blaine want to yell out that there was no one else, this part didn't apply, but he had to finish the song, then he could explain.

Oh, I'm holding my breath

Won't see you again

Something keeps me holding onto nothing

Blaine finally tore his eyes away from his friend, and closed them tightly as the chorus arrived. Tears threatened to fall, but he managed to keep them at bay.

Come on, come on, don't leave me like this

I thought I had you figured out

Something's gone terribly wrong

You're all I wanted

Come on, come one, don't leave me like this

I thought I had you figured out

Can't breathe whenever you're gone

Can't turn back now, I'm haunted

Blaine slowed down, and took his time getting the notes out, giving them just the right sound and emotion. This was a heartbreaking performance to watch. Even Mr. Schuester and Mrs. Shuester (Ms. Pillsbury) were clasping hands with glistening eyes.

I know…I know…I just know

You're not gone. You can't be gone. NO!

Blaine's foot hit the ground hard and he squeezed his eyes shut and brought a fist up to his heart, grasping his shirt for the second time in the song. He was going to lose it very soon.

Come on, come on, don't leave me like this

I thought I had you figured out

Something's gone terribly wrong

Won't finish what you started

Come on, come on, don't leave me like this

I thought I had you figured out

Can't breathe whenever you're gone

Can't turn back now, I'm haunted

Blaine slowed as the song was drawing to a close. His eyes were wetter, and his strength to keep from crying was deteriorating fast. He should have never done this, but Mr. Schuester asked for this week to be full of meaning, and this definitely had meaning.

Oh…

You and I walk a fragile line

I have known it all this time

But I never thought I'd live to see it break

Never thought I'd see it…

Blaine looked up at his fellow Glee clubbers as the song ended before running out the door. Only to have Mercedes follow him,

"Blaine!" she called to him as the two got further away from the choir room doors, "come here and talk to me."

Blaine whorled around, and looked at Mercedes, tears falling freely now. His eyes were bloodshot, and his face was contorted in pain,

"What Mercedes?" he asked a hushed tone.

"Is there really a someone else who makes you smile?"

Blaine sighed and stepped closer to Mercedes and sighed, wiping his eyes. The movement did no good; the tears were falling too fast,

"No. This song just fit my pain the best. Mr. Shuester wanted meaning, he got meaning."

Mercedes nodded in understanding,

"You need to tell him" she said simply before turning and walking back to Glee.

The 'him' she was referring to was Kurt. Blaine still remembered the day Kurt broke up with him like it was yesterday. It had been 3 months ago, in July. It was 2 weeks before he was leaving to NYADA. Blaine had pleaded, but it fell on deaf ears. Kurt was going to leave Lima with no strings attached. Blaine looked at Mercedes retreating form and the determination in her step. He could tell Kurt was going to get an earful later tonight.
