(Gotcha! sounds cool.)
Sora was now at a loss at what to do. Something bad was happening, and even the Witch of Time Crona couldn't stop it. He slowly sat up, looking around.
Everybody was now tense trying to fight these shadows off. Sora thought desperately, and thought hard. He didn't want to see this place end, he'd been given a mission and he'd finish it.
Sora's eyes open wide as he thought of something. "The heart..of a world.." This world, the Metaworld, or at least this version of it, had no heart. He remembered how Virgilia said some worlds were simply different. But if he could change that..maybe he could stabilize it's existence.
Sora closed his eyes..a tear drop went down his face. "Sorry Riku, Kairi..everyone. But..I'm gonna have to go for awhile again."
Summoning Oathkeeper, Sora, without heisitation, stabbed himself with the keyblade. His body dropped like a rock as his Keyblade disappeared. At the last second, Sora gave ownership of the Kingdom Key to Battler.
His heart floated from his body. A bright golden and yellow light shined from it..then the heart disappeared. It had fused with the Metaworld, becoming the world's heart.
The effects of the timeline erasure were undone by Sora's efforts, at least for now. "Crona..find the culprit..I will protect this place even if it means I have to do this." Sora's voice echoed.
Sora's sheer pure heart banished the shadows away from the Metaworld the moment his heart fused with it. At least for the time being. Somehow this had worked, and Sora's body lay on the ground, eyes shut.
Ownership of the keyblade was now Battler's.

Mickey had a sad look on his face. He slowly approached the boy, so as to not scare him. "Hey..what's wrong?" Mickey spoke softly. "How did you get here? and why are you crying?"
