This scenario is probably impossible within the current KH universe, but ever since I was spoiled for 358/2 Days I always wondered how Xion would react if she ever encountered Sora. This piece didn't exactly come out the way I wanted it to; it ended up being more of a character study on Xion. I may come back and expand if I get the urge. Tell me what you think.

She can't help but stare, watching as his spiked hair sways in the nonexistent breeze. He is seated with his back to her, legs dangling over the edge of the platform, fingers spread on either side of him.

The stained glass below her and the obsidian sky above are momentarily forgotten as she tentatively approaches him. The heels of her shoes make soft clink noises against the mural. She raises a hand to brush a lock of hair, black as the cloak she still wears, out of her eyes.

For Xion, the place is achingly familiar in a way that she both loathes and desires.

The distance between her and the boy becomes infinitely smaller, until she is standing directly behind him. For a moment she wonders why he hasn't heard her. But then, this is his heart after all. If she wasn't supposed to be separate in the first place, then perhaps in her rejoining with it, she has already faded into the background.

Xion brushes the thought away and moves to sit down, legs folding under her momentarily before stretching down over the edge (and for but a moment, she's back on the tower with Roxas and Axel – but as soon as it comes, it's gone). She and the boy are inches apart now, and she turns her head to look at him. His eyes stare up into the ethereal sky, trained on something she doesn't see, and his lips move silently. His fingertips trace patterns on the stained glass, occasionally moving up to finger the crown necklace that is partially obscured by his jacket. One hand strays into one of his many pockets and tugs something out; a star-shaped charm.

"Sora," she whispers, and her voice is almost as quiet as the pressing air around them (because she still doesn't want to accept this), but he catches it and swivels to look at her. Her breath stops in her throat as his cerulean eyes, mirror images of her own, (but no, I'm the mirror) find her face and she glances down and away reflexively.

"Hmm?" he inquires. He still holds the charm in one hand, twirling it lazily between his fingers, but he reaches out to touch her shoulder.

Xion winces at his touch and draws away. I'm not like you she wants to tell him, I can't be you, but her lies sour on her tongue. Her eyes find the charm, the smiling face in the darkness, and she is envious because he has everything. He has friends, he has love; he has his own light against the crushing shadows.

Xion knows why he isn't surprised in the least to see her; she is nothing now, nothing but another piece of the heart that she could never have.
