A/N This is pr the shortest fanfic chapter I've ever written. Oh well.

The Kastle Siblings Stay Up Late

Reginal draped the sheet over the ebony chairs. He triple-checked what he needed to prove Santa Clays' existence. Camera: check. Flashlight: check. Blankets: check. Rio: uncheck.

"Where could she be?" he wondered aloud.

He felt a sharp tug at the back of his head. Slapping at whatever has pulled his hair, he turned around.

"What was that for, Rio?"

She blushed angrily. "This time I'm going to prove he's real! You're wrong to think that it's Mommy or Daddy that fills our stockings," she said decisively.

He rolled his eyes at the bluenette seven-year-old. "Whatever. You got a clock?"

She shook her head. "I thought you got it."

"Why should I be the one to get it? I got everything else," he complained.

"Exactly!"

"Rio, that doesn't even make sense."

"So?"

"Just be quiet. I'll go get it," he decided eventually.

Clock now in hand, he returned to his sister. She had decided to braid her hair into three different parts and had begun to cry out of frustration.

"Look who's crying again," he teased.

She sniffed and wiped at her eyes. "Not me!"

"Whatever you say."

He lay on his stomach and glanced out the fort. When will my parents arrive, he wondered.

10:00. Nothing.

11:17. Still nothing.

11:53. Still no sign of anyone.

Reginal looked to his side to see his little sister peacefully snoozing on top of one of the stuffed animals she had brought in. He smiled to himself. She was the one that had been so adamant about doing this in the first place, and here she was, taking a nap.

But then again…

Exhaustion tugged at his eyelids. A short break shouldn't be that bad, right?

Reginal yawned loudly. He took a glance at the clock and frowned. 7:28. He had slept through it.

Gently he shook Rio. "Hey, Rio! Wake up. It's Christmas," he added.

Half-asleep, she punched the air, trying to attack whomever had woken her. "Whowokemeup?" she slurred sluggishly.

"I fell asleep before we could see him," he admitted.

She considered this. She sat silently thinking until she came up with an idea. "What if he made us fall asleep? What if that's how I always fall asleep on Christmas when I'm too excited to?"

He nodded, only partially listening.

Maybe that was how it worked.

Who knows?
