Recap:
"Gawrsh, Sora……we'll see each other again," said King Mickey.
"Are you sure?" Sora asked.
"Definitely, now let's close this door for good!"
"Uuuuugghhhhh"
Moaning was coming from behind the door where the King and Riku stood. It was the Heartless and they were on the move.
"Hurry, they're coming!" shouted Riku.
"Come on, Sora. Let's close the door together," Goofy said.
Together Sora, Donald and Goofy pushed the door closed. Before it was completely shut Sora met Riku's eyes.
"Take care of her," Riku said.
They both shook their heads in agreement and Sora shut the door. With the power of the Kingdom Key, he locked the door. It disappeared into the darkness.
Now we know Sora, Donald and Goofy went off to find the door to the light and possibly the King and Riku. But then again, Riku never did stay with the King. He met a man name DiZ. Sora was in a deep sleep and he needed his other half to wake up, Roxas.
In my story, that doesn't happen. Riku leaves the King, but never meets DiZ. Ansem the Wise (a.k.a. DiZ) died with his research. So this is what happened, Riku's side…his story.
