Twoshot-Without You I'm Nothing: Part One
"And Derek?" Casey called loudly.

"Yeah?"

"Don't forget about your date with Rachel."

Derek grunted, and walked over to his room, wishing Casey hadn't reminded him.

Derek slammed his bedroom door behind him, cranked up some music, and thought about what had led him to this horrible situation.

Flashback
"Look at her."

Derek turned his head to see a new blond girl, talking to a teacher.

Derek let out a low whistle, "Hot."

But as Derek turned his head back, he saw Casey looking from the girl to Derek and back with blood-shot eyes.

Derek bit his bottom lip.

He knew he shouldn't have done that, since her was secretly dating Casey.

Casey swung her messenger bag on to her shoulder, and was about to shut her locker.

"Hey, Casey," Adam Main said, he was the second most popular guy at school, after Derek.

Derek looked over at them.

"Hi, Adam," Casey said nervously.

"Are you doing anything tomorrow night?" Adam asked.

Derek jaw tightened, and his fingers curled into a fist.

"No."

"Would you like to go to the movie's with me?" he asked.

"Um, can I take a rain check?" Casey said, nervously.

Adam chuckled, "Yeah. Call me when you're available."

Casey gave him a tight smile, before walking away.

Derek shut his locker, and ran after Casey.

But Casey had disappeared, so he went to his car.

He found her at home already.

As soon as she had heard him come her, she dashed upstairs for her room.

Derek sighed.

It wasn't exactly his problem that he was a hormonal teenage boy.

He tossed his bag into his room, then stood in front of Casey's door.

He gently knocked on the door.

No response came.

"Casey," he said softly.

When she didn't answer, Derek tried to open the door, but it was locked.

At dinner, Derek and Casey didn't exchange a word.

And Casey avoided his glances at her.

Derek finally trapped her as she made her way to the bathroom later that night.

"I'm sorry."

Casey stayed quiet and looked at the floor, finding it more interesting than usual.

Derek had his hands on the wall, placed on both sides of her head.

"Smerek?"

Derek tore his gaze away from Casey's sad face, "Yes, Smarti?"

The next day, Casey was gone before Derek woke up.

"Casey told me to give you this," Nora said, handing Derek an envelope, as he padded downstairs.

As soon as Casey's name was mentioned, he was immediately fully awake.

He grabbed the envelope full of eager and excitement.

Nora gave him a strange look, but left it at that.

Derek tore the envelope, and saw a note hand-written with Casey's hand writing.

-Derek

It's hard for me to say this. But I think we should take a break. It seems like your losing interest and givin' up on me. I hope you have a good date with Rachel. (Timothy's at seven tonight)

♥ Casey

p.s. No sarcasm intended.

Derek froze with shock.

"Did Casey just break up with me?"

The question repeated in his head.

Then he was out the door.

He raced to school, and over to Casey's locker, but stopped halfway there.

"Hey Adam," Casey said, as Adam passed by her.

"Hey Casey," Adam said with a smile.

Derek's fingers curled into a fist, and his jaw tightened.

He was thankful that no one else was there.

"About the rain check..." Casey said slowly, with a grin.

Adam chuckled, "Are you doing anything tonight?"

Casey shook her head.

"Timothy's?" he suggested.

"Sure."

"I'll pick you up at six forty-five. See you tonight," Adam said with a grin, before walking away in Derek's direction.

"You okay dude?" Adam asked Derek, who was burning with fury.

Derek nodded a stiff nod, hoping Adam would get away from him asap.

Once Adam was gone, Derek flew over to Casey.

"What the hell do you think you're doing?!" Derek spat.

Casey ignored him.

"Hey Rachel," Casey said, giving a wave.

"Hey Casey," she said, then turned to look at Derek, "Hey Derek. I can't wait for seven o'clock to come," she gushed, and Derek stared at her bulging chest.

When Derek finally snapped out of it, Casey was gone.

Derek mentally hit himself.

For the rest of the day, Casey avoided him.

And when they had the same class, she would sit away from him, and Rachel would sit in her spot.

It made Derek frustrated.

He had never been so far apart from Casey.

And he hated staring at the blonde's head for so long that day.

As soon as the final bell rang for the day, Derek made a dash home.

But Casey wasn't there.

She came through the front door an hour later, with shopping bags.

Derek looked at her with a raised eyebrow, but she didn't even glance in her direction.

Not once.

Half an hour later, the house wasn't as quiet.

Everyone was home.

"Derek," Nora called, "Ask Casey if she can baby-sit Marti tomorrow evening."

Derek slowly went up to Casey's room, with a good excuse.

Derek knocked on the door.

"Come in," Casey said.

Derek pushed the door open, but froze once he saw Casey's appearance.

Casey looked up into the reflection in her mirror, and frowned, "Derek? What're you doing in my room?"

Derek snapped back to reality, "Nora wanted to know if you could baby-sit Marti tomorrow."

"Sure," she said, turning to face him, "Can you close the door behind you, by the way?"

Derek nodded, before awkwardly shuffling out of her room, closing the door behind him.
End of Flashback

And that led Derek to where he was now.

The doorbell rang at six forty-seven.

"Door!" Casey yelled.

The rest of the family had gone out for dinner, which only left Derek.

Derek swung the door open with a clenched jaw.

"Hey dude," Adam said with a grin, "Where's Casey?"

"Dressing up," he mumbled, dropping his butt onto his recliner, leaving Adam to stand there.

Adam nodded.

Then he asked Derek quietly with a hopeful grin, "Do you think I'll have luck getting into Casey's pants tonight?"

If Casey hadn't chosen that second to come down the stairs, Derek would have punched the lights out of Adam.

Casey's shoes came tapping against the floor, and the two males turned to look at her.

Casey smiled in Adam's direction, "Hey Adam, has Derek treated you well?"

She turned to Derek with a long look.

Derek shrugged it off, and stared at the blank television.

"Have fun with Rachel!" Casey said before closing the door behind her.

Derek waited for a full minute before getting up, and reaching for his car keys to meet Rachel at Timothy's.

Derek scanned the huge room at Timothy's.

It was full of students, Casey and Adam were sitting at a table.

Adam said something to Casey, which had Casey giggling.

Derek was just about to go over to them, and interrupt.

"Derek! Over here!"

Derek turned his head when someone called him, to see Rachel, patting the empty space beside her on a brown couch.

Derek scowled, and reluctantly went over.

For the next half hour or so, Derek snuck glances at Casey and Adam, mostly Casey though.

Adam would whisper something into Casey's ear, and Casey would giggle, peck him on the cheek, or give him a playful punch.

Adam saw Derek looking over at them once, and winked with a grin.

Derek gritted his teeth.

Adam wouldn't get what he wanted.

Not under his watch.

He excused himself, and walked over to Casey.

Derek grabbed Casey by her underarm, and dragged her off her chair.

"Sorry, Adam. Family issues. Gotta get home," Derek said quickly, before dragging Casey to his car.

But Casey didn't get into the car without a fight, "Derek! Let me go."

"Sorry, baby girl. Not on my watch," Derek said, wrestling her on to the passenger seat.

Derek obviously won, since he was stronger than her.

He crawled over her to get on to the driver's side, so she wouldn't run while he walked outside the car to get on to the driver's seat.

Derek reached over and shut the door.

He quickly started up the car, since Casey wouldn't run if the car was running.

Casey crossed her arms over her chest, and stared out the window.

"Case, talk to me." Derek said, as he parked the car on the driveway, and Casey still hadn't said a word.

Casey stalked out of the car, and into the house.

The rest of the family wasn't home yet.

Derek sighed, and followed her into the house.

Derek closed the door, and when he turned around, Casey was standing there, finishing a banana, and chewing the last bite furiously.

Casey tossed the banana peel into the small green bin (if you live in Toronto, you'll know what a green bin is. It's basically a garbage can), and turned around with her hands on her hips, "I don't get what you have against Adam."

"Case. He's bad news," Derek said, hanging up his coat.

"And you weren't?" Casey snapped.

"But I care about you."

"Yeah right," Casey snorted.

Derek looked her in the eye, "You know I did, and still do."

"Yeah, whatever," Casey said rolling her eyes.

"I love you, Casey."

"Whatever you say, Derek."

"You know I do."

"Yeah. Well you have a strange way of showing it. Checking out Rachel," Casey said with an example.

"Casey. I have a reputation to keep."

"Yeah. Then which one's more important: Your reputation, or me.?" Casey said loudly, looking him in the eye.

Derek tore his gaze away from her, and looked anywhere but at her.

"Fine. Well I hope your reputation is worth it," Casey said, before going up to her room, slamming the door behind her.
