It was Demyx's first week in the Organization. So far, he had:

--freaked out when he woke up butt naked in the rain in the middle of a dark alley with no recollection of who he was
--been given a heavy, thick, hideous black cloak to wear
--learned to call his "weapon" out of nowhere (and by weapon, we mean a ridiculously large cello-looking thing)
--discovered he had the element of water (he flooded the castle)
--been spanked by Zexion (several times)
--managed to piss off every single one of the members by the third day

It was an exciting time in young Demyx's life. So much to learn, so much to do…the fun never ended, and neither did the swats at his head. So far he had learned:

--Larxene's room was off limits
--Luxord always wins at euchre, no argument
--Axel would prefer it if no one touched his spiky hair
--Never ask Xigbar about his missing eye
--Xemnas has no qualms whatsoever about killing anybody
--Marluxia does not need suggestions on special fertilizers, thank you
--Never suggest that Lexaeus takes steroids

…And much more. Such was the life of this Nobody, the "baby of the family", if you will. Because he was so inexperienced and new to this state of (not) being, the older members felt that it would be in everyone's (no one's?) best interest if Demyx was watched constantly. I mean, yes, he was a perfectly capable teenager, but they really didn't want to leave him at the castle only to come home and find that he had, once again, flooded the castle in his excitement over beating The Legend of Zelda.

AKA they had to take turns babysitting him.

So here he was, Demyx and his good ol' buddy Saix.

Now, Saix did not like kids. He hated them so much that he refused to admit he ever was one. He had begged and pleaded with Xemnas to be taken off the Demyx-sitting schedule, but Xemnas had threatened him with photos of a drunken night with Xigbar. But that's another story. So anyways, he did his best to ignore Demyx's prattling as he focused his attentions on a lovely paperback book entitled Temptations and Chocolates.

"Saix, let's do something."

"No."

"Something FUN!"

"I don't do fun."

Demyx pouted. "Well," he whined. "I guess I'll go somewhere else and leave you alone with your book." He began to amble out of the room, glancing over his shoulder with a smirk on his face and was almost out the door when Saix suddenly glanced up.

"Oh, no you don't. Get your ass back in here, kid. You're not going anywhere."

"I'm not?"

"Nope."

"I'm not not, or I'm not?"

"You're not."

"Or am I? Because in reality, I'm not necessarily…not…right? Right, Saix?"

Saix turned around and squinted his eyes. "Huh?"

"Exactly," whispered Demyx knowingly.

Saix shook his head and turned back around in his chair. "Demyx, I don't know what the hell you're talking about, but as far as I'm concerned…"

Sneaky Demyx took this opportunity to run out of the room. "Catch me, Saix! Betcha can't catch me, old man! Ha ha ha!" Saix jumped up and sprinted after the Nobody, with a murderous glint in his eyes. Old man! Oh, how he hated kids.

Two hours later, Saix had successfully discovered Demyx hiding in the pantry and dragged him back to the room by his ear. He barricaded the door and resumed reading his book. Demyx was a bit worn out, to be honest. That had been a fun game, except for the whole getting-the-shit-beat-out-of-him part. He twiddled his thumbs for a moment and looked up excitedly.

"Hey Saix, wanna spar?"

"…No."

"Wanna play Monopoly™?"

"NO."

"Wanna bake cookies?"

"Yea---…..NO."

Demyx gave up. He sat down hard on the armchair and swung his feet back and forth. Remembering a cool little trick Axel taught him, he shot a bit of water out of his finger. He played around with his new power a bit, till he could aim it. Then he furtively shot a thin jet of water right into Saix's lap. Now it looked like widdle Saix has peed his pants. Demyx's shoulders shook with silent laughter. Now what to do?

A lightbulb went off over Demyx's head. "Hey…we can open portals in other dimensions, right?"

"No."

"Yeah, we can. I've seen you guys do that."

"Oh, you caught me," Saix answered absentmindedly.

"So we can?"

"So it would seem."

"Any dimension?"

"I suppose."

"No way, man."

"Way, man." Saix rolled his eyes and turned back to the big, stuffy book he was reading.

Using his power of darkness, Demyx blindly conjured a small portal at random and peeked his head through, just to see what was there. A pointy face stared back at him.

"…Who the hell are you?" asked Spike Spiegel.

"Oh! Hi. I'm Demyx. Ah, um, is Faye around?" He glanced about the room excitedly.

Spike scratched his mossy little head and looked at him funny. "Um, no, she's not."

"Oh. Um. Dang. Well, I'll be going, then. By the way, man, your show was great. But hey," Demyx leaned really close and whispered, "dodge that last one, okay?" He straighted up and waved. "See ya!" And with that, he repaired the rip in the time-space continuum and was never seen in the spaceship again.

"…the hell?" said Spike.

Meanwhile, back at the ranch…

The other members of the Organization were returning one-by-one to the Castle Oblivion from their various activities. Lexaeus and Xigbar had been at the gym pumping some iron, Marluxia had just purchased a state-of-the-art halogen light, and Larxene had just come from Knockturn Alley hauling a dirty sack over her shoulder and was acting jumpier than usual.

Xemnas returned from who-knows-where. He always went alone and never said anything about what he did while he was gone. Demyx had been speculating this for awhile. Secretly he thought Xemnas went to Chuck-E-Cheese's. But it was just speculation.

Immediately upon Xemnas's return, Saix threw himself at Xemnas's feet. "Oh, Xemnas! Tell me I never have to care for that wretched excuse-for-a-Nobody again!" he all but sobbed.

Xemnas sighed as he watched Demyx trip his way down the hall, free at last. "Don't worry, Saix. I'll repay you. Quite handsomely, too…" he waggled his eyebrows as Xemnas/Saix fans squealed across the globe.

Epilogue: After forty-five frustrating minutes of searching for his room, Demyx found it. He curled up on his bed and, after a hot cup of chamomile tea, watched The Real Folk Blues. What a great day.
