A/N:

Big shoutout to KH_FLUTE () for just being an awesome reviewer! And to answer your question… yes, this is a sort-of alternate ending, but it still has some sort of basic Canon structure! This means: Vexen will, I repeat: WILL wind up dying.

So read on!

What happened afterwards with Yukia was something Vexen did on a whim. He gently sewed stitches along the curves and ragged lines of her not-quite-healed wound. He could see the muscles working inside her chest, and her heart was beating steadily; despite the loss of blood, she seemed fine. Her chest slowly rose and fell, breath after breath- Vexen was almost jealous. Had he never created her, she wouldn't have to-

"What am I thinking?" Vexen's stitching was done, and he moved away from their shared bed. Night was falling, and fast- he could see the heart-shaped moon that was better known as 'Kingdom Hearts'. He watched Yukia sleep, and she looked completely at peace. Her pale skin and short, black hair seemed to have a rather ghostly aura to them.

Vexen thought she would fade away if she was given the chance.

Yukia sleepy deeply, as if she never slept a wink in her lifetime. Dreaming of nothing she was- a blank space inhabited only by her conscience. Her thoughts flow freely, then a figure appeared in front of her, cloaked in black with its back turned towards her.

"Vexen?" she called out of her mind, hoping the Chilly Academic would hear her. "Vexen, is that you?"

The cloaked figure turned around, and then pushed down its hood. Pale blonde locks fell over his shoulders and his dead, green eyes looked lifeless.

She smiled."Vexen, what are you doing-" Vexen form started to diminish into the darkness, black and gray wisps of it flowed around him.

"Goodbye." His body quickly became nothing, and she was left alone in the blank space again.

Waking up, tears gently streamed down the lines of her face. "Don't leave me again…"

Vexen heard her move to get up, and heard her weep. He didn't move a muscle- afraid he might wake up and this was all a dream. That would have been for the best… He shook his head violently and sat down on the bed next to Yukia, rumpling the gray sheets and casting shadows. Yukia clung to him, her head nuzzling into his chest.

"Never again, never again…" she rocked back and forth, only relaxing when Vexen wrapped his arms around her body.

"Never again, Yukia…"

Yukia then fell back into a dreamless slumber, and Vexen was relieved. Maybe he could get some sleep as well. He tucked them both underneath the covers and looked out the window at Kingdom Hearts.

"Will I have a heart, too, someday?"

[TimeSkip: Next week]

Vexen was always in his lab, never coming out these days. ["I'm trying t help Yukia," he would say, then shut the big metal door again.] Yukia would always be hanging out with Demyx and Zexion, singing together and reading passages from the Lexicon. These times were always quiet, until Demyx got sugar high or Xigbar came along to try and convince the poor boys to go out drinking with Luxord and himself. At those times, Zexion would grab her hand, stand up, and go to his room, where they would read together in peace.

Only after the new Replica came did things start to change.

The Riku Replica had clung to Yukia for the past few days, and Vexen was getting curious. He questioned Repliku about it, but he simply replied "She's nice."

"I don't understand…" Vexen rubbed the bridge of his nose as he walked into his bedroom. Repliku was curled up against Yukia, arms wrapped around her waist and face smothered into her breasts. [Xigbar would get a nosebleed. Vexen thought.] While she had her hands buried deep in his silver hair. Both were sleeping contentedly, but only Yukia's chest rose and fell repeatedly. Her soft breaths blew against her choppy black locks, making them puff out into the air, only to fall back down when she sucked in air. She was always just…there.

Vexen hoped his plan worked, for the sake of this girl, who killed and grieved and hurt so much…
