Part One Lost Memories

Chapter One The Accident

Casey woke up in a room that wasn't her own, her room wasn't its dark shades of purple, her bed wasn't as soft and comfortable as her own, and most of all there was an annoying beep that wouldn't shut up. She blinked; a light was on exposing the pale blue walls and a small picture of a landscape in the room she was in, Casey had no clue what happened but she knew where she was, she was in the hospital.

"Mom!" Casey cried out, but her mom didn't come. Frantically she tried to remember how she got here, the last time she was in the hospital was when she had to get her appendix out the day of her sweet sixteen, she remembered Max coming to visit her along with…

"Derek." Casey whispered. The beeping noise suddenly got louder, and she turned seeing it was a heart monitor. Frowning she wondered why her heart picked up when she said her step-brothers name, but pushed the thought away wondering where her family was.

"Hello? Nurse?" Casey called out, but again no one came and she was getting frustrated.

"Lizzie! Edwin? George!" Casey was shouting now as she moved the covers from the bed trying to get up. She heard movement coming from outside her room.

"Der-ek!" she shouted, and just as she got off the bed the door burst opened to reveal Derek himself. His eyes wide, seeing her just standing there.

"Casey?" he asked confused. He looks different, Casey thought noticing that Derek's hair was longer than normal, and his t-shirt looked a bit too tight on him. Since when did he start working out?

"Derek… what am I doing here? What's going on, what did you do?" she demanded asking him all these questions. Derek blinked. When the doctors told him Casey would probably lose her memories from the impact she received he didn't actually think she would be calling his name, and blaming him for this. At first he believed Casey did remember, and that's why she was yelling for him, but instead he saw the spark in her eyes the same spark she got whenever she was ready for a fight against him, this wasn't his Casey.

"Hold that thought, Case." He said shutting the door. Casey just stared at him mouth open, since when did Derek call her Case?

Casey grabbing the monitor was about to chase after him, when the door burst open again revealing Nora Venturi-Macdonald and George Venturi.

"Oh Casey." Nora said moving towards her daughter grabbing her in a tight hug.

"Mom?" Casey asked surprised seeing her mom look so huge, not to mention her hair was cut way too short. Casey barely recognized her.

"Honey before you freak out, you we're in an accident and have temporary amnesia." Nora went on to say. Casey shook her head, about to argue with her mom when she caught herself looking at a mirror that hung against the wall. In a flash Casey moved out of her mother's arm to gape at herself. Her hair wasn't the sunny blond highlights she had put in, but back to its original chocolate brown.

"What happened to my hair? It's supposed to be blond!" Casey shrieked turning to stare at her parents. Nora bit her lip turning to look at George.

"Casey, you dyed it for graduation next month." George said. Casey frowned.

"Graduation? But I just became a senior." She said turning to look at Derek who groaned out loud. Nora and George gave him a look turning their attention back to Casey.

"Casey, you were in a skiing accident you hit your head and you lost a few of your memories." Nora said as soothingly as she could, but this was Casey and she was bound to freak out—which she did.

"That doesn't make sense, I'm fine I remember everything if I had amnesia I wouldn't know who you guys were." Casey argued in that tone of hers. Nora looked at George pleadingly, but it was Derek who went up to Casey.

"Then please tell me Casey, why is your Mom pregnant?" Derek said. Casey opened her mouth, and then closed it she didn't have anything else to say.

"Come on Casey, you're a smart girl look at us, do we look the same?" Derek kept asking. Casey did look at them, and he was right they did look different, she knew the moment she looked at Derek when he opened the door, his hair was in fact longer, and not to mention his pale skin looked a bit darker almost as if he got a tan? She than looked at George and her Mom and sure enough they weren't the same parents as in her memories, her old memories.

"Mom?" Casey asked suddenly feeling tears in her eyes.

"Casey, it's going to be okay." Was all her Mom said, but Casey knew it wouldn't be okay at all.

"I'm going to go get the doctor." Nora said giving Casey a kiss on her forehead as she left.

"I'll call the kids, there gonna be so happy." George said smiling as he and Nora left leaving the two of them alone. Casey wiped her eyes and took a breath; she was trying not to freak out. She was trying really hard, but the fact that Derek was in the room wasn't making it easy at all; especially since there was a memory she still had in her mind she just remembered but didn't want to say.

"Derek? What happened?" she asked.

Derek closed his eyes as he stepped closer sitting on the edge of the bed, he was trying really hard to keep cool but seeing the way Casey was looking at him with those vulnerable eyes. There were a few tears trailing down her cheeks and all he wanted was to reach out and wipe them away, but he couldn't. So he forced his hands on the bed making sure he didn't do anything funny.

"Actually…um that's my fault." He said a bit guilty as he looked away from her.

"I accidently let go of your arm. Well technically you let go we were fighting and you just let go of me. I was teaching you how to snowboard."

Casey rolled her eyes; she wasn't even a snowboarder she liked skiing which she still did poorly what with her clumsiness.

"What were we fighting about?" she asked. Now Derek hesitated, how was he supposed to tell her they were fighting about them?

"Just the usual stuff, but you took it offensive and you let go at the exact moment we were going downhill, and you went too fast hitting a tree." Derek said.

Casey flinched; she hoped she never remembered that part because it sounded like it hurt, not to mention the big bruise she had on the side of her forehead made it look like she hit something hard.

"Why were we skiing? Family trip." She asked. Derek shook his head.

"No school trip for the seniors." He said. Casey frowned, if this was a school trip for the seniors than why did she spend it with Derek of all people? Why didn't she just ask Emily for help, or Max? Wait, where was Max?

"Derek…can I ask you something personal?" she asked. Derek froze, there was no way Casey was going to ask him about that was she? He knew there was no way she was going to forget what happened between them but still, she wouldn't dare ask that?

"What happened to me and Max? Weren't we still together?" she asked him. Derek felt relieved that she was asking about Golden boy, but then he suddenly got jealous, why the hell was she thinking about Max?

"No, you guys broke up at the end of junior year. I thought you still remembered junior year?" he asked. Casey groaned as she lay back in bed.

"I don't know, everything is still jumbled up it's like a puzzle and I'm trying to piece everything together. Like I thought me and Max were okay, and you're dating Sally…"

Derek flinched, and Casey suddenly sat up realizing she made a mistake.

"Oh Derek I'm sorry I just…forgot." She whispered as she saw Derek's guard face go up as he looked away from her beginning to study the painting in the room.

"It's fine Case." He said, but he didn't sound fine at all.

Derek was not fine, how could she bring up Sally? He didn't care about Sally anymore sure he thought he was in love with her and everything, but the only reason he ever went for her was because he thought Casey no longer wanted anything to do with him. This was all just fucked up Derek didn't know how he was going to get through this.

"Okay, maybe you should make a list of the things that have happened and maybe some reminders I shouldn't say." Casey said. Derek looked at her thinking she was joking but once he saw her serious face; he broke out laughing.

"You may not have your full memories, but you're still a Keener." He chuckled as he reached out placing a stand of hair that came undone from her pony-tail behind her ear. Casey for a second forgot to breath, the moment Derek reached out his face had turned so soft and gentle, and when his fingers barely touched the side of her face. She felt her skin crawl, and all she could remember was that night. The night that changed her mind about Derek, but she couldn't think about that night. Not when he reached back his hand, his eyes going hard as he closed up again.

"I should go find Nora, I need to call Emily and tell her you're okay she's been freaking out, not to mention keeps hitting me." he said with a wince. Casey giggled and through his guard, Derek smirked.

"Get some rest Casey, and I'll see about that list." He said as he got up. Casey nodded as she lay back down, and the moment her head hit the pillow she was out like a light.

Derek smiled as he sat back down, watching her for a few minutes as her breathing slowed down to a steady pace. He reached out his finger slowly trailing her cheek.

"Come back to me, Case." He whispered so low he didn't think he even said it, but he did. He leaned forward, his lips touching her forehead as he got up and left the room. For a split second he remembered Marty telling him a story about a sleeping princess, and how she woke up from true loves kiss from a prince. He chuckled, shaking his head.

He was no prince, but he hoped Casey would wake up with that tender look on her face every time she saw him, but he knew this wasn't a fairytale.

Casey laughed as she threw her head back against the couch; they had the house all to themselves while the family was out doing who knows what, but they didn't care. They always loved these moments they got to share it was one of the things they got to cherish.

"So are you seriously willing to sit through an hour and watch Pride and Prejudice?" she asked leaning as she took a spoon digging in to the rocky road ice cream on her lap.

"It's a terrible way to waste our freedom, but its better going out." Derek said grabbing Casey's spoon before she could eat it.

"Der-ek!" she squeaked. He just laughed.

"What? I like ice cream too." He said with a wink, making Casey giggle.

"Seriously Derek we don't have to watch this." She said setting the ice cream on the table. Derek smirked grabbing Casey around the waist.

"So tell me princess, what do you want to do instead?" he asked her softly his face inches away from hers. Before Casey could tell him, he was already moving, their lips barely touching.

"I want you." Casey managed to whisper just as Derek's lips touched hers.

Casey woke up with a gasp, she was still in the hospital and the clock on her wall said she'd been asleep for two hours.

Two hours after Derek left, while she slept and dreamed about him. That wasn't a dream, Casey thought. She knew in her heart that wasn't a dream at all but a memory. In her dream Casey still had her blond highlights which meant this was probably…after that night. She groaned leaning back onto her pillow. She could feel tears in her eyes but she blinked them away.

She could still remember that night like it was yesterday, she was glad that out of all her missing memories, she didn't forget the night that changed her feelings about Derek.

Flashback

Casey didn't stick around as she flew up the stairs ignoring the way everyone was cheering for Derek and Kendra making out in public. She didn't know why she was so upset; she should have known Derek would sabotage her dates. Which is why she told Kendra that Derek in fact like making out in public—a lie of course. Everyone knew Derek hated P.D.A. but this was Casey's way to getting even too bad she felt like crap.

She closed her door about to change, when it opened revealing the cutest guy she'd ever seen, dark black hair and matching dark brown eyes.

"Um sorry, I thought this was the bathroom." He said in deep voice that sounded nothing like Derek's at all.

"Oh it's to the right." Casey said her voice stuttering a bit. He smiled at her.

"Shouldn't you be at the party looking for a date?" he asked her leaning casually against her door frame. Casey shrugged.

"I should, but no one's caught my attention." She said. He smiled at her.

"Don't worry Casey, I'm sure someone will." He said with a wink as he closed the door. Casey just stared at the door shocked that the cutest boy knew her name, which meant he probably went to her school. Why has she never seen him before? She needed to ask Emily information about him and possibly get his name.

She turned around, unzipping her dress when the door burst open slamming it shut, making her jump. At first she thought it was the cute guy, but to her horror it wasn't him. It was Derek.

"Get out Der-ek!" she screamed. For some reason he locked the door, and she wandered if he was going to kill her for what she told Kendra.

"What the hell is your problem Casey?" Derek demanded.

"Me? What about you how dare you sabotage my dates! You practically begged our parents for this party and then you go and ruin it for me!" she shouted. Derek rolled his eyes.

"Relax I knew you weren't actually serious I was just helping you out." He said with a smirk.

"Well I guess I was doing the same pushing Kendra to kiss you." She snapped. Derek's eyes flashed.

"You did it on purpose, you know I hate P.D.A." he said. Casey shrugged a small smile playing on her lips.

"Guess we're even." She said, and that's when she realized her dress was unzipped from the back.

"Now get out, I'm changing." She said hoping she wasn't blushing but Derek didn't move. He must have noticed her discomfort, but she didn't understand why he didn't leave, what possessed him to take a step forward.

"Why didn't you stay and watch Casey?" he suddenly whispered close to her face. Casey started to panic. They've never been alone in her room before, not counting the times they were either planning something, or just fighting. But this, this was different.

"Why did you sabotage my dates Derek?" She asked instead. Derek shook his head, and somehow they were holding hands as Derek slowly pushed her back, the back of her knees hitting her mattress but they stayed standing.

"Derek…we're you jealous?" Casey whispered. Derek closed his eyes, his forehead resting on Casey's, her eyes were half closed as they just stayed like that while the music below got louder.

"Derek…"she said softly, making him groan.

"You have no idea how hard it was watching you with all those guys." He said. She opened her eyes, and was shocked to see how brown his eyes were; they weren't dark like she always imagined, but a honey golden brown.

"You're with Kendra." She said. Derek shook his head.

"I'm only with her because you set us up; I was trying to make you jealous." He admitted. Casey found herself smiling.

"Well it worked." She told him. Derek's eyes suddenly soften as he lowered his head to brush his lips against Casey's jaw.

"Then you know that I've been jealous all night." He whispered. Casey's skin crawled and before she could ask him why. Derek's raised his lip up and softly brushed against hers.

Casey rose on her tippy toes never realizing how tall Derek was as he wrapped his arms around her waist, one of them going to her exposed back.

"Casey." Derek whispered. As he continued to kiss her pushing her back as they fell on her bed. Casey should have stopped him this wasn't right at all, she wasn't making out with just anyone. She was kissing Derek, her step-brother, and her enemy.

But she couldn't stop him; because she's wanted this the moment she saw him but had to stop herself, but now there was nothing stopping her now.

"Derek." She said softly as he trailed kissing down her neck.

"It's okay…I won't…Casey." He said between kisses, Casey smiled a bit never seeing this sweet side of him, so caring. She pulled him by the shoulders catching his lips again as he tenderly set the pace. Casey never imagined that she would be kissing Derek of all people.

Yet, here she was. She wrapped one hand around his neck trailing up to touch his hair, she always wanted to run her hand through his hair, and she never thought it would this soft under her touch. She didn't know how much time passed, minutes, maybe even hours but she didn't care. She just didn't want this night to end, but unfortunately it did.

"Casey!" someone pounded on the door bringing both teens to stop what they were doing, and just lay their so still.

"Yeah mom?" Casey called out wincing when her voice cracked.

"Oh sorry Casey I didn't know you were sleeping, the parties over did you wanna say bye to your guest?" Nora asked. Derek snorted as he went back trialing kisses on her neck.

"Mom, I'm in my pajama's go tell Derek it's his party." She said as her voice shock a bit when Derek started biting on her skin.

"I can't find him, I'll go check the backyard I think I saw him and Kendra head out there." She said as she left, but not before Derek froze as he sat up. Casey sat up re-zipping her dress as she climbed off her bed heading to her window that looked out to the backyard, and sure enough Kendra was outside, and she wasn't alone.

"Derek." She said softly.

"Forget it." He said as he came up behind her, kissing her cheek but Casey shook her head.

"No, Derek we can't." she said as she pulled away. Derek groaned as he followed her.

"Please don't tell me you regret what happened." He said. Casey frowned shaking her head.

"Of course I don't regret it, but Derek you have a girlfriend not to mention if the door wasn't locked my Mom would have caught us!" she exclaimed. Derek frowned.

"You're thinking about the family." He said.

"Aren't you!" she said a bit sharply.

"Of course I am Casey, but I'm also thinking about myself and I've wanted you from the first time I saw you." He said taking a hold of her shoulders.

Casey could feel tears in her eyes, she wished she was selfish, that she should think about herself like Derek was, but she couldn't be selfish. She needed to do the right thing.

"No Derek, we can't. This was a mistake." She said.

She saw the light leave Derek's face, the soft expression he had was gone replaced by his cold eyes as he took his hands off her, taking a step back.

"Whatever you say, princess." He said icily as he unlocked her door and walked out closing it shut behind him. Casey slumped down to the floor as she cried her eyes out.

The next day while her parents told the kids about the party and how amazing it was, Derek and Casey sat in silence neither one of them looking at the other.

"So Casey, did you get to meet someone?" Lizzie asked. Casey actually took a peak at Derek who was stabbing his food with his fork.

"Yeah, but turns out he has a girlfriend." She said softly. Derek stopped stabbing his brussels sprouts, but didn't look up.

"Oh don't worry Casey, you'll find someone else who's single and will like you for you." Nora said. Casey smiled sadly, too bad the only guy she wanted, was sitting right in front of her.

"Thanks Mom, but I think I may already found someone." She said suddenly remembering about the cute guy she met last night.

"Oh, a new guy?" Lizzie asked with a smile. Casey nodded, the entire time staring at Derek, who sat frozen in his chair.

"Yeah, I saw him last night but I didn't catch his name, but I'm sure I'll see him at school." Casey said.

"Casey likes a boy, Casey likes a boy." Marty began to sing.

"I don't know him yet, Marty." Casey said.

"Well looks like your party went good, right Derek?" Edwin said elbowing his brother.

Derek stood up in a flash, and without looking at anyone grabbed his leather jacket and left the house.

"What did I say?" Edwin asked confused.

"Derek's just having a bad day; he and Kendra broke up last night." George said.

Casey suddenly felt like throwing up as she excused herself and ran up the stairs to the bathroom, throwing up her brussels sprouts and whatever else was in her stomach.

"Damn it Casey…why do you have to follow the rules?" she asked herself as she cried on the bathroom floor wishing she could chase after Derek, and tell him she changed her mind, but she couldn't and she cried all night in bed, and the next day she went in search for the cute guy she met at the party, and Derek gave her the silent treatment.

Casey wiped her tears as she looked up at the ceiling in her hospital, she wished she could go back in time and run after Derek, but it was too late.

"I need to fix this." She said out loud, but first she needed to rest because tomorrow the whole family would be here to take her home. Not to mention she needed time to think things through, especially since half a year was wiped away from her memory.

"I'll get the truth." Casey thought as she went back to sleep hoping she'd get another dream with her and Derek.
