Chapter 1: Silence.

"Casey," Derek came from his bedroom and made his way out into the living room, one that he shared with his roommate and step-sister, Casey McDonald, "Cas--"

She waved an angry hand, "Shhhh!" She sat up crossed legged; watching the TV intently.

He sighed and took a seat next to her. "LOST? Reall--"

She took her hand and put it over his mouth, "Please shut up. Flashback!" She took her hand away and went back to the show that occupied all of her mind. Derek sighed and sat back while he waited for her. He was startled when she screamed in excitement. Casey laughed at herself and looked at Derek, "Okay, it's a commercial, what do you want?"

He shook his head in joke disappointment, "It's about time." She frowned purposely. "Anyway, are you finished packing or are you too busy watching your stupid shows about people getting stranded on islands?" He smirked.

She threw him a fake glare, "Of course, I'm finished packing. What kind of a question is that?"

He shrugged, "A stupid and very obvious question."

Casey grinned and decidedly wanted to tease him, "Aw, you just want to talk to me, Derek. It's okay. You can admit you like having conversations with me." It was a normal habit of hers to do this to him.

He scoffed, "Someone's full of herself." He shook his head and whined, "I'm so friggin' bored, Casey!" He wasn't really bored, he was just looking for an excuse to be near her or just talk to her. Derek just wouldn't admit it to her. Neither would he give her the satisfaction of gloating. At least not yet.

"Pshh. Right." She joked, "So you wanna go out?"

He blushed, "Wh-what, Casey?" He snorted, "We can't--"

She stared with confusion, so she decided to clear it up for him, "Go out like for a drink or something?"

He laughed nervously, "Right. Right. Yeah, sure."

She smiled, "Alright, well leave me alone for a while so I can finish LOST!" She put excited emphasis on the title.

He laughed at her and got up and went back into his room. Casey looked back toward his door and smiled then immediately got back to her show, "AHH! JACK! DON'T LIE!! IT'S KATE!!"

Derek went into his room and quickly rummaged through his closet for something decent to wear. He wanted to look nice for his night out with his roommate, his step-sister, the person he had grown to actually like. Was it more than like? He wasn't sure, but it was something. Derek was positive it was something, he just couldn't shake off…or maybe he just didn't want to shake it off.

His cell phone rang, "Hey Sam."

"Hey, D. What you up to tonight?"

"Nothing," Derek lied as he picked out a nice polo from his closet.

"Hm, well, aren't you leaving tomorrow?"

"Yep," Derek was hardly listening to Sam.

"Then let's go out tonig--"

"Can't," Derek let out. He heard Casey scream from the other room and started laughing.

"What's funny?"

Derek took a quick peek out his door and saw her in her intense LOST mode, "Casey screaming at that dumb show."

"Ohhh…"

Derek could hear the smugness dripping in his voice, "What's that supposed to mean?"

"You don't want to go out because you wanna spend more time with Casey." Sam scoffed, "I mean isn't it enough that you live with her? Not only that but you chose to take her on the trip instead of me? Messed up, D."

Derek rolled his eyes, "No, it's not even that. I am still packing and you know I only chose Casey to come with because she begged like a crazy person for weeks!"

Sam laughed, "Uh-huh. You know, if I ever win MVP for the team and get a much radder vacation spot, you aren't gonna be my first choice. Maybe a backup."

"Ha-Ha." Derek let out sarcastically with a laugh, "Well I'm gonna finish pac--"

"Is that what they call it now?" Sam couldn't resist.

"Shut up." Derek laughed, "Like I was saying, I'm gonna finish packing. I'll talk to you later."

"Aight, D."

Derek got dressed and looked at himself in the mirror, "Tonight. Have fun. Tomorrow. Hawaii, maybe I'll tell her. I'll tell her." He was about to walk out of his room but went back to the mirror to take one last vain look at himself. He smirked, "How could she resist this." Derek finally tore himself away from his mirror and out of his room, "Hey Case! I'm ready." He went over to turn the TV off and found her asleep on the couch. He was upset to say the least. Derek sighed and looked down at his clothes, "Got dressed for nothing," he looked down a sleeping Casey, "Thanks a lot, Case." He kept his gaze on her for a minute longer and softened at the sight, "Can't be mad at 'cha though." He kneeled down and put his arms underneath her neck and her knees.

Derek picked her up and immediately she wrapped her arms around his neck, "Jack…" she mumbled, "tell Kate you love her…"

Derek let out a tiny laugh, "Too much LOST, Casey." He walked over to her room and gently dropped her in her bed. She lazily got comfortable, frightening even as she started to snore and drool. Derek still smiled, "If Jack could only tell Kate, Casey…he would…" He raised an eyebrow at himself, "Metaphors…argh! You're rubbing off on me." Derek stood up and was tempted to give her a little kiss on the forehead. "She's sleeping, she won't know," he whispered to himself as he bent down and gave her one, "Night, Case." He left.

"Night, Derek." She mumbled and turned over to get comfortable for bed again.

He went back to his room, where he got changed back into his PJ's and hockey tee. "Timing. All about timing, D. Hawaii. Perfect." Derek quickly fell asleep and awaited the next morning where he would fly off to a romantic or hopefully will be romantic get-a-way.

--

"Case?" He knocked on her bedroom door, "Casey?" He sighed with annoyance, "Casey, get your ass up! We have to go!"

"Derek, leave me alone…" She groaned tiredly.

He opened up the door and brought himself in her room, "Casey, we are going to miss the flight if you don't wake up. So get up!"

She tossed and turned in her bed. She finally stopped and sighed, "Fine."

He teased, "You see, Casey, you should've just stayed up with me and slept on the plane." She rolled her eyes and got out of the bed, "You got your stuff all ready?"

"For the last time, yeah," she sat on the edge of her bed, "Can you grab my bag for me?" She smiled innocently at him, "Please, Derek?"

He busted out into laughter, "No. You got two hands attached to anchored arms. Pick it up yourself."

She wrinkled her nose, "Quite the gentleman." She got up and picked up her duffle bag and dragged it out her room. Derek just watched her struggle and laughed at her, "Why are you laughing at me, Derek?" He shrugged. "You haven't been a jerk to me in quite some time, please don't start it up again. At least not when we go."

He rolled his eyes, "Yeah, yeah." He walked past her and went to get his things.

Casey went into the bathroom to freshen up. She took a look in the mirror and sighed, "I hope everything goes great during this trip." She couldn't shake that feeling that Derek was planning to be a prick because he was starting already that morning.

She was startled from her thoughts when he loudly knocked on the door, "Casey, hurry up. I gotta take a leak!"

Casey already felt disgusted, "Ugh," she opened the door, "that really wasn't necessary."

"Well sor-ry," he squeezed right past her and she stared at him in disbelief. He was about to go but he turned his head to look at her, "You gonna watch me or…"

She immediately shut the door, "Why is he acting like such a…ugh!" She stomped over to her room and put on her "Plane outfit" and sat on the couch with her bag waiting for Derek. It was Casey's turn to be impatient, "What the hell, Derek, you're the one taking forever!"

He came out with his duffle over his shoulder, "Calm down. I'm ready. Let's go."

Casey took a deep breath and got up to follow him out the door. She just couldn't help but think things were just gonna get worse from here.

--

"Derek…" Casey whined.

He sighed as they stood in front of their row, "What Casey?"

"Can I have the window seat?" She smiled brightly. Even though it didn't work earlier, she thought 'why not try again?' "Please?"

It didn't, "No. You're lucky I'm even bringing you with me. So I take the window seat." This time he smiled brightly at her and it was all sarcastic. She could tell.

Derek made his way in the row first and Casey reluctantly second. Casey only hoped that the seat next to her would just stay vacant. Casey stared and stared as people passed her row and fortunately for her no one sat in that third seat. Casey let out a breath of relief and stared at the repetitive images being shown on the portable TV in front of her. She looked over at Derek, who stared intently out the window. Casey rolled her eyes and decided to just ignore him. She sat back and got comfortable. Subconsciously, she closed her eyes and it was abruptly interrupted by the huge smelly man that squeezed his way into that third seat.

Derek turned and saw Casey and the huge guy. He nudged her on the shoulder and Casey looked at him, "11 hours of that." He started to laugh at her.

Casey shook her head in disgust at him. "I didn't realize I was stuck in the past," she muttered and stared ahead. Derek rolled his eyes and stared out the window. Casey sat back in her seat and immediately closed her eyes to salvage what was left of this plane ride. Things were just going downhill from here. It would continue to do so.

--

"Casey!" She was being shook on the shoulder from her left. She arched her eyebrows and got comfortable again, "CASEY!" she was being shook once more and at that split second she felt her stomach drop significantly. She abruptly awoke and finally the sounds matched her sight as the people around her were freaking out. She looked to her left and saw Derek in panic mode, "Casey! Finally!!"

Casey was terrified, "Derek? Derek! What's going on!!"

The Flight attendant went on the intercom, "The Pilot has turned on the fasten seatbelt sign. Please return to your seats and fasten your seatbelts." The plane took another plunge.

He shook his head in terror, "Casey, I don--"

The oxygen masks fell from their compartment. The flight attendant came on the intercom once more and this time Casey couldn't make out anything she was saying. All she heard was panic, crying, yelling as she tried to get her mask on. She was struggling and Derek took it from her and helped her put it on. "Put yours on!" She had to yell due to the commotion and the pressure from the downward motion of the plane.

Derek quickly put his on and grabbed Casey's hand. They both stared up at the ceiling because that was all they could do. The motion going faster and faster and Casey squeezed his hand tighter. They were going down and it wasn't long before they knew it'd be over. Casey didn't know what would happen from here. Would she and Derek die? Would they survive? Would one make it and the other no? All the thoughts ran through Casey's mind in a blink of an eye.

It was Derek's turn to squeeze her hand and he motioned for her to look at him. She looked at him and it was the last pair of eyes she'd seen before everything became black and silent.

so...
