NOT SO PREDICTABLE

DISCLAIMER

Written for my own challenge of Derek finding something out about Casey. Life With Derek belongs to Disney and "Enter Sandman" belongs to Metallica. Takes place after Male Code Blue. I don't know Sam's last name, so I'm gonna make somethin' up.

Fifteen-year old Derek Venturi was in his room changing into grunge clothes. Just then, there came a knock.

"Yeah?" he called.

"I've got some of your grubby clothes," he heard his fifteen-year old stepsister Casey MacDonald say. With an annoyed sigh, he walked across his room and opened the door.

"My clothes are not grubby," he snapped.

"Whatever. Just take your stuff," she snapped back. Derek did so. It was then that Casey noticed her stepbrother's attire.

"What are you wearing?" she asked.

"Clothes," he responded.

"Where on Earth would you be going that you would want to dress like that?" Casey questioned. Yeah, she was under the impression that Derek didn't put a lot of thought into his outfits, but this was overkill, even for him.

"Party. Sam's picking me up," Derek answered shortly.

"Really?" Casey asked.

"Yes. And don't get any ideas about coming. 'Cause you're not invited," Derek responded. The last I need is my dopey stepsister tagging along, he thought to himself. Not that she'd even come, but still. It was the principle of the thing.

"We'll see," Casey tossed back. That's so typical. He thinks he can just order me around, she thought bitterly. Just then, the doorbell chimed. Casey and Derek raced downstairs. Derek shoved Casey out of the way and then answered the door.

"Jerk," Casey said.

"Hey, man. Ready to go?" Derek queried, ignoring her comment.

"Sure," Sam Chambers answered.

"Hey, Sam," Casey greeted.

"Oh. Hi, Case," Sam acknowledged, his mouth curving into a grin. "You wanna come with us?" he offered.

"No. She'd hate it," Derek answered quickly.

"Well, that probably means I'll love it. Let's go," Casey declared. Derek frowned. Dang it, he thought. She flashed Derek a grin and walked out with Sam, leaving Derek to glower. At the party, which was in full swing by the time they arrived, Casey, Sam, and Derek saw that a karoke machine had been set up. Derek's lip curled in disgust.

"Karoke? What a joke," he stated.

"I think it's kinda cool," his stepsister responded.

"You would," he tossed back, rolling his eyes. One of the hockey players, which Casey recognized as one of Sam and Derek's friends, walked up to the machine and indicated to the deejay which song he wanted. Then, he started belting out an off-key rendition of Metallica's "Enter Sandman". Casey blanched.

"He's totally butchering it!" she protested.

"Like you could do better?" Derek scoffed.

"Totally," Casey answered.

"Yeah. I'll believe it when I see it," Derek scoffed with a smirk. Yeah, right. Casey probably doesn't even know who Metallica is, he thought to himself.

"Fine. You will," Casey told him. He probably thinks that I don't know a Metallica song when I hear it. Well, I'll show him, she thought to herself. As soon as the singer finished, Casey walked up to the stage and indicated that she wanted the same song.

"Oh. This'll be good," Derek smirked. She's gonna look so stupid, he inwardly gloated.

Say your prayers little one

don't forget, my son

to include everyone

Derek's jaw dropped as Casey sang on-key without even looking at the words. How'd she know this song?

tuck you in, warm within

keep you free from sin

till the sandman he comes

Casey really got into the song, moving her head and body to the beat.

sleep with one eye open

gripping your pillow tight

exit light

enter night

take my hand

off to never never land

"Wow. She's really good," Sam commented.

"Yeah," Derek agreed in surprise. Dang. I didn't think she could sing like that, he thought.

something's wrong, shut the light

heavy thoughts tonight

and they aren't of snow white

"Is that Casey MacDonald?" a boy asked.

"Heck, yeah!" his friend confirmed.

"Man, she sure knows how to rock!" the first boy approved. His friend agreed.

dreams of war, dreams of liars

dreams of dragon's fire

and of things that will bite

sleep with one eye open

gripping your pillow tight

By the time Casey got to the chorus again, the crowd was singing along with her.

exit light

enter night

take my hand

off to never never land

"All, right! Go Casey!" Sam shouted. Derek grudgingly admitted that his stepsister was a pretty good singer.

now I lay me down to sleep

pray the lord my soul to keep

if I die before I wake

pray the lord my soul to take

hush little baby, don't say a word

and never mind that noise you heard

it's just the beast under your bed,

in your closet, in your head

exit light,

enter night

grain of sand

exit light

enter night

take my hand

we're off to never never land

Derek stared in shock as Casey stepped down from the stage and rejoined them.

"What?" she asked.

"How---how did you know that song?" her stepbrother stammered.

"Didn't I tell you? I love Metallica," came her answer

THE END
