A/N - And I am FINALLY done! Took me a while, huh? When reading this chapter, please keep in mind that I wrote it within today (all mistakes are mine) and I'll probably come back to fix it, and I really tried to stay away from the cliche of Futuritis. So it might be disappointing :/

I do not own Life With Derek.


.

In feeling the Fever...

"Casey!" Grabbing her wrists, Derek wrenched her hands off her face. "You'll be fine."

Keeping her eyes screwed shut, she shook her head. "I can't do this," she mumbled. "What was I thinking? I can't do this."

Derek grabbed her shoulders and shook her. "Open your eyes so you can see this hideous make up you made me wear."

Against her better judgment, she popped one eye open only to burst out laughing. "Oh my God."

"Yeah," he shrugged bemusedly. "And I'm still the hot one between the two of us."

Her laughter stopped as she narrowed her eyes at him. "I'm not getting into this with a zombie. And you need to tell me how Sadia did." She eyed him worriedly. "Were they better than us?"

Sighing, Derek scratched the back of his head. "Lets just say, that it's going to be a tight race."

Casey's face immediately scrunched up as she let out a small whine. "Why did I ever think we could do this?"

"Look, we'll be fine," Derek said in assurance, even as his step-sister gave him a skeptical look. "All we have to do is go out there and do slightly better than the rehearsal."

"Well, not exactly," Casey stated thoughtfully. "You really have to be more on the beat when we do the simultaneous turns. And you should also hit your lines sharper. And not to mention when you-"

"Oh, so it's all me now?" He scoffed. "Like you're so perfect."

She glared at him. "I know this is hard for you to believe, but I did do this a bit more longer than you, you know."

Presenting a step-brother and sister act; Casey McDonald and Derek Venturi.

They looked at each other.

"This is it," Casey said excitedly as she started shaking her hands to rid the nerves.

"Yeah," Derek muttered as they moved towards the space between the curtains, waiting for their cue to get on stage.

Finding her step-brother oddly silent, Casey looked over her shoulder at him. "You'll be fine."

He scoffed again. "Of course I will. All I have to do is remember the hundred things you told me."

"Oh, um... There's one more thing," she muttered as her eyes swept the audience through the curtains.

"What?" he asked in a bored tone.

"Maybe this time, unlike our rehearsals, you could grab my waist instead of my..." She stopped, just as a blush crept up her neck.

"Your..."

She cleared her throat, her gaze staying firmly away from him. "My thigh."

Derek stayed still, surprised by what she just said. "Why?" he asked mockingly. "Does it make you uncomfortable?" he drawled as he leaned towards her.

At that moment, the lights came on. Using this opportunity, Casey avoided his gaze and stepped onto the stage. Derek watched her as the music started and she started moving with practiced movements. He could have sworn he had seen fear in her eyes. But then it might have been a trick of the light. Shrugging it off, he waited for his cue.

The things he does for McDonalds.

In getting rid of the Teddy...

Casey sighed happily as she floated into the kitchen, a large grin on her face. "Don't you just love dates?"

Derek looked up from his busy job of making a sandwich to roll his eyes at her. "I'm sure it's a lovely concept to someone who usually spends her Friday nights with a book, but yeah, dating's great," he said mockingly.

His tone effectively burst her bubble, which caused her to glare at him. "Please, the last time I checked, sucking face with a cheerleader does not amount to dating."

Derek's lips split in a lecherous smirk. "You saw that, did you?"

"Ugh. I just wish I could un-see it." Smiling again, she moved around the island to get herself something to drink. "Too bad you aren't willing to get proper tips from Truman. I think I finally manged to get some gentlemanly quality out of him."

"Ha! Good luck with that." Derek laughed mockingly before grabbing his sandwich and making a move to leave the kitchen. "We both know you'll kick him to the curb at some point."

"Oh?" Casey asked more out of sheer curiousness. "And why would I do that?"

"Because he's a 'Teddy'," Derek said, shrugging like it was a 'no-brainer'. "And who wants a 'Teddy'?" With a shudder at that very thought, he left; leaving his step-sister staring at him in surprise.

.

In Awakening to the reality...

"I give up!"

Derek whipped around to stare at his step-sister as she started collecting her things. "What? You're giving up? You can't give up!"

"Watch me," she said in a chirpy tone as she stood up from his bed. "You're playing a video game while we are supposed to be cramming for the biggest test of our lives...so far."

Derek immediately turned off the computer and faced her. "See? It's no longer a distraction." She rolled her eyes, having heard this promise countless times before. "I'm serious this time."

"Really?" She questioned as she placed her hands on her hips. "Do you promise to pay attention now?"

He looked up thoughtfully. "Not that I'm complaining or anything..." He smiled sheepishly as she glared at him. "But the way you teach me doesn't really give me an...incentive to study."

"How's this for incentive? If you fail, you will end up homeless and alone, and I will get to order you for the rest of my life."

"Hmm...yeeeeah.. that doesn't sound too bad. At least you'll feed me, right?"

Casey's eyes widened almost comically. "You see? This is why I can't tutor you. I have tried everything? What do you want me to do? Flash you every time you get an answer right?"

The way his glance fell to her chest at that moment was totally coincidental. "Well..."

Her eyes widened further as her tone became deeply threatening. "Derek-"

"How about you make me a sandwich every time I get a set of questions right? That's incentive," Derek said quickly, cutting her off before she could embark on a rant to end all rants.

She eyed him suspiciously. "Fine. A sandwich it is." She sat back down on his bed primly. "And just so you know..." she said in an authoritative voice. "I will never flash you."

"Right." He grinned. "You keep telling yourself that."

The resulting glare she gave him was so worth him fake-playing-a-video-game just to annoy her.

.

In not taking Chances...

Derek groaned as he parked the car in front of their house. "Seriously, will you just stop crying already?"

Unbuckling her seat belt, Casey sniffled and threw a careless glare his way. "I'm sorry, but being cheated on is not how I like to spend my Saturday night." She got out the car gracelessly, slamming the door shut behind her.

Derek sighed as he got out of his own side. "We all told you the guy was scum, but you just wouldn't listen."

"Oh, I forgot," she called out sarcastically as she kept her back to him. "You and Truman understand each other. You two could be brothers."

Derek slammed the car door and made his way towards her. "Why do you always do that?"

His question caused her to face him, her sniffles pausing in surprise. "Do what?"

"Compare me with the jerks you date."

She stared at him in confusion. "I don't you compare you to them."

"Of course you don't." He mocked. "Derek, why can't you be like Sam? He's so sweet. Why can't you be like Max? He has aspirations. You and Truman are so alike." He narrowed his eyes at her. "I gotta say, that last one, not so true."

"Please," Casey scoffed. "You and Truman are cut from the same cloth. You are two peas in a pod. All you care about is sports and girls."

"Really? And that differs us from all the other guys, how?" Derek questioned seriously as he took a few steps forward to tower over her. "What Truman did today, I would never do."

"You were kissing some random girl you just met," she protested.

"I am single." He moved even closer when her expression froze. "I have no girlfriend waiting for me to call her once I get home. I wasn't with my girlfriend at a party where I kissed a girl. That was Truman. Not me."

"I...I know that," Casey stammered, her eyes falling from his intense gaze.

"Then why are you determined to make it sound like I was the one who cheated on you?"

She stayed silent for a moment, her mind processing what he just said. "Because you would," she muttered softly, more to herself. She looked up to see her step-brother staring at her in surprise. "If I had been there with you, you would have kissed that girl anyway."

Derek shook his head in disbelief before he looked up as if asking for an answer from above. "Why do I even bother?" He took a deep breath before he grabbed her shoulders and made her face him. "Casey, believe it or not, if you were my girlfriend, I wouldn't even be looking at another girl, let alone kissing them. And if I do fall for a girl, I break up with the girl I am with, before I pursue her. You taught me that." He let her go with a tired sigh. "I thought you knew me better than that." He looked over her head towards the front door of their house. "Shall we go in then?" Without waiting for an answer, he started for the door; all the while aware of how her sniffles had increased as she followed him.

.

In welcoming the Surprise...

Casey poked her head out into the backyard and found her step-brother where she knew he would be; sitting on the back porch nursing a beer.

"You know you're underage, right?" Taking his silence as an invitation, she sat down beside him. "And George won't be happy that you got into his stash again."

Derek continued to drink his beer in silence, seemingly ignoring the persistent person sitting beside him.

"Would you like to talk about it? A new addition to the family is bound to change the family dynamic. Are you prepared for the little boy or girl who will be the connection between our families?" Derek sipped his beer in silence, and Casey huffed in annoyance before falling into a companionable silence beside him.

"Do you think," Derek began thoughtfully, surprising her, "the baby will have your eyes or mine?"

"Um.. I don't know," she said carefully, her glance rising to focus on the stars that littered the sky. "I haven't really thought about it."

"Casey, you're a lot of things. But a liar..."

She bit her lip thoughtfully before she turned her attention back to her companion. "I think he or she will have your hair, and my eyes."

He smirked at her, making her suddenly aware of exactly how close they were sitting. "What a combination."

"I know, right? Imagine if he inherited George's sense of chaos, and Mom's need for perfection."

He grinned. "The kid will be so confused."

Casey let out a light laugh before agreeing. "The poor thing."

It took a moment longer before their grins fell simultaneously.

"Look at us," Casey said as she smiled encouragingly. "We're actually having a decent conversation about the newest coming addition."

She expected him to make a scathing remark about her sensitivity, but instead, he shrugged. "What did you expect? Things will change."

"Well, yes," she mumbled carefully. "But for the better."

He looked at her critically then, his gaze penetrating. "You think so?"

Casey fought the urge to look away from him. "I do. What can be better than having something that connects us?" Her eyes widened at the same time he smirked. "I meant.."

"I know what you meant," he said mockingly. It was then that she realized that the humour didn't reach his eyes. "How about we toast to our coming brother?" He picked up another beer, opened the bottle cap and handed it to her.

"Or sister," Casey said automatically before taking the bottle from him without thought.

He raised his bottle in a mock salute, and even though it went against her own rules of social conduct, Casey clinked her bottle against his and took a sip. The liquid that went down her throat surprised her, causing her to sputter the instant it went down. And which in turn, caused Derek's grin to widen.

"You're such a lightweight," he said laughing.

"And you're a bad influence," she snapped back as she held her chest and hoped that her little chocking moment wouldn't kill her.

Derek just continued to laugh as he sipped his beer, occasionally looking at her and laughing harder when she glared at him. Finally, she found that she couldn't keep avoiding the issue.

"Aren't you at all upset with the thought of a baby?"

He stopped laughing to look at her seriously. "Are you upset?"

She could tell that his answer would depend on hers. "I am. A little."

"Why?"

She found this question ridiculous. He should know why. A baby was like the unknown. Something new. Something that could change... everything. "I don't know. I just am."

He shrugged. "That's not good enough."

"What are you talking about?"

With a heavy sigh, Derek turned towards her, effectively bringing him even more uncomfortably closer. "Are you upset because you will no longer be doted on as a Princess, or are you upset because the baby will change everything?"

Unknowingly, she leaned closer towards him. "What do you mean by everything?"

"I mean.." She leaned even closer, and didn't miss the movement when he cocked his head to the side slightly while his eyes fell to the silver necklace that hung around her throat. "Things will change between us."

His eyes finally met hers, and her breath caught. He was moving towards her, bringing himself even closer to her. Her eyelids began to droop seemingly of their own accord as did his. When she felt his hot breath on her lips as his face hovered over hers, every memory she ever had with him went through her mind. Especially the most important one.

"Emily." Her voice came out as tiny a puff of breath against his skin. He immediately froze and started to move back. "You're with Emily," she whispered shakily. "And I... I'm with Truman."She tried to meet his eyes with hers, but he looked away from her forcefully. "I should go." With weak legs, she stood up, determined to run back into her room and pretend that moment, whatever it was, never happened.

She got as far as opening the door, when she heard him say her name, and felt the pull of her arm as he turned her to face him. She barely had time to think as his lips captured hers and his arms pulled her flushed against his body. Maybe it was instinct, but she immediately responded, her hands immediately fisting themselves in his t-shirt. He kissed her forcefully, one hand at the back of her neck, while the other gripped her hip tightly. She had never been kissed so roughly before; with movements quick and clumsy, and hot, heavy breaths mingling gloriously against each other. Even when his tongue expertly sought entrance, she allowed it, kissing him back just as passionately as their tongues met again and again in a heated battle for dominance. She pulled him against her, her own hands roaming across his chest, his arms, his back; yearning to be closer. She had never wanted anything more, never felt this heat inside her that kept rising until she was sure she would burst with want and need.

Derek finally broke the kiss, while pushing himself away from her. They looked at each other, both wide eyed and breathless.

"This never happened," he said strongly. It would have been believable had his voice not been in a low, husky tone. He waited a while longer, waiting for her to protest, before turning on his heel and leaving, closing the door behind him as he did so.

Casey stared unseeingly at the spot where he stood before. There was no reason for him to say what he did. She would take this secret to the grave.

.

In planning the Future...

Derek finally managed to get out of the clutches of his family, when the one person he had been avoiding spending any alone time with, cornered him.

"So...I guess we're going to the same school then, huh?"

Derek eyed her warily as she stood before him, her arms crossed and ready for battle. "I guess we are."

"I think there is some business we have to take care of before we leave."

He raised an eyebrow at her. "Oh? And what pray tell would that be?"

She dropped her gaze from him, seemingly unsure with her proposals. "We have been living under the same roof for quite sometime now. We started out at enemies-"

"Still enemies," he piped in, earning a glare.

"And things have... happened between us." He shifted uncomfortably. "But now I think that it's time to make amends." She uncrossed her arms and stepped towards him, causing him to look at her in mild surprise and curiosity.

With a grand smile she held out her hand. "Friends?"

He looked down at her hand, then at her. "This means that what didn't happen, never happened, right?"

"Right," she said beaming. "This means that we will be civil and courteous in exchange for silence."

"Does this also mean silence when I try to hook up with a college chick?"

Her eyes narrowed. "Derek."

With a smirk, he took her hand firmly in his and shook it vigorously causing her to laugh. The laughter soon died down, and he felt her try to squirm her hand from his. He kept her hand within his grip for a while, before giving up and letting her fingers slide against his. She looked at him nervously, the hand he held twitching beside her.

"Right. So I guess we're..."

"Friends," he finished for her, although he was sure that there was no smile on his face.

"Right. Friends." She smiled warmly at him before heading towards her bedroom and shutting the door after her.

He stared at the worn poster of 'Swan Lake' for a moment longer before the need to distract himself overwhelmed him. Maybe he could look over the Queens course catalogue. There are bound to be classes where there are enough girls who are willing to be his distraction for the coming year.

A/N - And I begin my 'Yay I'm Done' dance..lol.. Thank you so much to all those who encouraged this experiment which I started a few years ago. I know the updates have been slow, but thank you for sticking it out with me, and making me smile with every review left behind :)

Some have asked whether I intend to do a Vacation with Derek chapter, and I thought about maybe doing a -5 moments within the movie- thing. The possibilities are endless since it's the last bit of canon for LWD.

So I ask you this. Do you think I should do an epilogue using VwD?

Right now, I'm marking this as 'complete', but if I decide to do this, I will set it back to 'incomplete' and get on the absolutely tedious job of watching Vacation with Derek to come up with moments..*snort* as if watching Michael Seater hurts my eyes.. LOL..

Thank you my readers! You rock! All of you! :D
