This is another idea of mine. Don't be repulsed by the Luxord. Please. He doesn't appear much in the rest of the story.
Oh, this mainly focuses around Zexion, around the time right before Marly gets there. But it's not Marluxia/Zexion. Nor is it Zemyx. But you can take it that way, I guess.
Oh, the disclaimer, right…uhh…I disclaim. Square owns them. Here we go!
It had been a rainy sort of spring morning in The World That Never Was; if the flowers that were planted there did not die immediately upon being exposed to the nothing-air, they would be rejoicing in the revelry of the first rain since the warmer months had come. Luxord had fallen asleep the night before listening to the rain fall on the roof, like a thousand tiny diamonds on the Castle. The next morning, the rain was still drumming down, at full force, and it didn't look like it would stop any time soon.
He had been awoken that morning by a squeal of purest delight from his neighbor. Since Luxord's arrival to the World two months ago, he was still surprised by Demyx's frequent, joyous laughter. Joyous. Did the Ninth member know nothing of their situation? There was no joy to behold in the lack of a heart.
"How old is he?" Luxord asked, later that morning. Xigbar and Lexaeus looked up from their coffee and newspapers, respectively. The three of them sat in the library, circled around a table with their assignments spread out forebodingly.
"How old is who?" Xigbar asked, returning to his warm mug of coffee.
"Number Nine." Luxord said. He looked out the window down to the courtyard, at the blond little nobody half-dancing in the rain below.
"I believe he's…seventeen. He'll be eighteen next week, though." Lexaeus replied calmly, skimming a paragraph in the newspaper and then folding it up to look over his assignment. Luxord gaped, turning away from the window back to his comrades.
"What?! Eighteen? The boy acts like he's less than fourteen! He can't b-Xigbar, what's wrong?" Luxord asked, for Xigbar had been staring at his coffee with a sad, wistful look on his scarred face.
Xigbar sighed, "You know, he didn't always act that way. He actually used to be way more mature. He's only been like this for maybe four or five months before you got here."
"Really? So He's going through a phase or something?" Luxord asked.
Xigbar turned to Lexaeus, who had been reading over his assignment quietly, trying to ignore the two.
"Hey, Lex," Xigbar said wheedlingly, "How 'bout you inform our newest member of that little incident?" Lexaeus looked up from the papers.
"I wasn't there, remember? I was in London at the time, researching those chimney-sweeping Heartless." Lexaeus retorted.
"Well, what happened, then?" Luxord asked.
"Well," Xigbar began, "Demmy wasn't always like as…happy-dancy-singy as he is now." Lexaeus added, "Mmm, quite the depressed child. Xigbar, let's tell him."
Xigbar nodded, "But you know, after this, you might not like our Number Six as much as you did before."
"I'm ready to take that chance." Luxord promised.
Okay, this isn't over! This is just chapter, like, negative-one. There's more to come and it'll be a lot more interesting, I hope. Please review!!
