A/N: Welcome back! After a much needed hiatus, we're back with our weekly prompts & GleekMom wasted no time in giving us a challenge. This prompt occurs in my Dream Lover verse, but it's AU because I made the choice in the story that it would NOT be Sebastian that Kurt saw with Blaine. At the time, there was way too much hate for Sebastian and I was worried that it would take the fic in a direction it was never intended. I am also shocked that months later, my original flashback idea, and the storyline overall, have come much closer to canon than I ever wanted (Kurt pulling away; talk of Blaine cheating; Klaine breaking up;). I'm just grateful that it appears Klaine will reconcile much sooner in canon than they do in Dream Lover. So that being said, here's how it would have played out if Sebastian had been on that piano bench instead of some faceless Warbler.

Prompt #15: Write a scene for one of your current or past fics that you were afraid to write.

Character(s): Kurt Hummel, Blaine Anderson & Sebastian Smythe

Words: 641

Date: November 7, 2012

Innocence Lost

I had flown home two days early to surprise Blaine. After dropping my suitcases at home, I drove to Dalton, arriving just as Warbler practice was scheduled to end. I walked the gilded hallways to the recital room. As I approached I could hear Blaine singing softly, playing the piano beautifully. And then another voice I didn't recognize filled the air. Blaine was singing a duet with another Warbler. I listened as they sang in perfect harmony. I took a few steps forward and caught sight of them seated together on the piano bench.

I froze.

Blaine was sitting shoulder-to-shoulder with Sebastian Smythe. His meerkat face was burned into my mind from all of his inappropriate posts on Blaine's Facebook page. I had called Blaine in tears the first time I saw Sebastian refer to him as 'sex on a stick'. Blaine had sworn he was harmless, had said that it was just how Sebastian was, that he was more open about his sexuality than any other gay man in Ohio. I had believed him, of course. I had no reason to think that Blaine would cheat on me, or do anything as hurtful as to flaunt his lover where all our friends could see.

But now that I saw the two of them lost in their own world, Sebastian looked anything but harmless. And Blaine looked a lot less innocent.

There was a pause in their singing as Sebastian leaned in and whispered something into Blaine's ear. I watched as my Blaine blushed at the words of another man. I felt my fists clench as my eyes filled with tears. I wasn't sure how it was possible to be filled with rage and despair at the exact same moment.

I couldn't hear their conversation, it was murmured between them. I stood there transfixed, not knowing what my next move should be. And then I heard Blaine laugh, his golden laugh, the one that I foolishly thought only I could elicit.

I realized I couldn't remember the last time I'd heard it. Or worse, the last time I'd been the one responsible for coaxing it out of him. And that thought, that heartbreaking thought, shocked me to my core. I felt like my entire world was crashing around me. I heard my strangled cry before I could clamp my hand over my mouth.

Blaine and Sebastian turned their heads at the sound. Blaine jumped off the piano bench and tripped and stumbled trying to get to me.

"Kurt!"

I heard the shock and joy mingled together when he called out my name. I really should have focused on the joy.

"Sorry, I'm obviously interrupting something here." My throat was tight, each word clawed it's way out of my mouth.

"What?!" Blaine froze, mid way between me and Sebastian. He glanced over his shoulder at Sebastian, who looked far too smug for my liking, knowing exactly what I would think I was interrupting. Blaine didn't miss the look on his friend's face and when he looked back at me, his eyes were swimming in worry.

I turned on my heels and stormed out of the room. Rachel would have been impressed with my exit.

Blaine chased me down the hallway and outside the building. I reached my car before he caught up to me. He grabbed my arm and spun me around.

"Kurt, Sebastian doesn't mean anything to me." Blaine told me, his eyes begging me to believe him.

But I couldn't. I wouldn't. Even if it was true, it didn't matter any more. Because I'd realized that I didn't mean nearly enough.

"We're done." I said coldly. As my heart turned to ice, Blaine dropped his hand, as if he could feel the freezing through my skin.

That was the last time we spoke until I saw him on the train.
