A/N - Hey, sorry guys, I was writing this chapter before I realized that it was really an extension of Chapter 2. So here... The new, revised version. I'm not usually this indecisive.

I do not own Life with Derek.

Someone once told her that gasping and smacking one's step-brother was not very lady-like. She ignores them on a daily basis.

"Ow!"

She rolled her eyes. "That hardly hurt, you big baby."

"I've been driving for hours. I'm tired and I'm sensitive right now. Could you not go all She-hulk on me?" She gasped and raised her fist, Derek cowered behind his hands. "Casey.." He began soothingly. "In case you have forgotten, I have the bouffet coupons with me. If you want to remain alive during this weekend, you will not abuse me."

She forcefully dropped her hand. "Fine." She said through gritted teeth. "I hate that I'm broke."

"Really?" He said with a wide grin. "I love that you're broke." He looked up in mock thoughtfulness. "Who was it who said that she'll be earning way more than me for the rest of her life?"

She crossed her arms and narrowed her eyes at him. "For your information, being a part-time librarian is an extremely fulfilling job. Not like yours. What do you have to do? Hold up a toothpaste and smile?" She finished with a scoff

He snickered. "It was a beer commercial, Case. And just because you're jealous of my popularity-"

She snorted. "I am not jealous."

"Really?" He leaned forward, his eyes twinkling. "Cause it seems like you are. It's okay, sis. When you're old and alone, I'll pay Edwin to look after you."

She shoved him lightly. Sort of. "You do that. I'm sure waiting on me is way easier than following your every order. And like I said, I'm not sleeping with you."

He winced at the very thought. "Er.. yeah. You are."

"Um.. No. I'm not."

"Why do you think I brought you here?"

"Because you're nuts. We're not doing that again."

"We did it several times." He said flippantly. "What's the big deal?"

Her eyes widened. He was way to casual about this. "Thrice, Derek. We did it thrice . The first time was a drunken mistake. The second time, we were just tired and it just happened. The third time-"

"You came into my bed willingly." She smacked him, again. "Ow!" He glared at her as he rubbed his shoulder. "What's the big deal? It's the best nap we have ever had." She glared at him, but he stayed put, oddly unaffected, which was highly disappointing. "Admit it, Case. You like sleeping with me." He rose his eyebrows suggestively.

Her face scrunched up in disgust. "Ew. No. It was just..." He looked at her expectantly. "We were just..." He raised his eyebrow at her. "Shut up." She snapped, defeated.

He let out a light laugh, which to her sounded eerily like the laugh that guy from SAW had. Figures the only evil family member she has, laughs like a psychopath. "I don't like it as much as you do. But you have to admit, I'm insanely comfortable." She narrowed her eyes at him, which only succeeded in making his grin wider. Stupid Derek and his stupid sense of humour. "You used me for your finals, so I'm using you for my hockey game." He came forward and grabbed her shoulders. "This is what family is for."

Rolling her eyes, she shrugged his hands off her. "I did not use you for my finals. I just thought that.."

"Since you were panicking, a good nights' rest is what you needed to calm your nerves. Hence the visit to Casa de Derek."

She hated it when he was right. So, she continued to glare at him, just to project her displeasure."I'm still not happy about this."

"When are you ever happy about anything?" She opened her mouth to reply, before he cut her off. "Right. So..." He faced the bed again. "Like I said before, I get the closet, the table, and three quarters of the bed. You can leave your things on that chair." He pointed at one lonely chair in the corner.

She glared at him. "Do you want me to hit you again?"

"Fine." He rolled his eyes. "You can have the other chair too."

Picking up her bag, she faced him. "You know what? I was crazy to think that I could actually survive a weekend with you."

He smirked, shoving his hands in his pockets. "So, what? You're leaving now?"

She let out her own smirk. "Yeah. Unless you give me a reason to stay."

He raised his eyebrows in surprise. "Casey McDonald wants monetary compensation? Can anyone say prostit-"

"Don't you dare finish that sentence." She said, her voice a deadly low. He kept looking at her in amusement, which was highly annoying. What was she? A pet? "My point is..." She walked over to the bed and dropped her bad, turning to face him, her game face on. "I will be giving up my weekend to..." She winced. Ugh. How difficult it was to say the words.

"Sleep with me." He helped out with a grin, thoroughly enjoying her discomfort.

She glared at him. "Yeah. So. I think it's only fair that I get something for my trouble."

He looked at her thoughtfully for a second. "Like what?"

She shrugged casually. "I don't know. How about...a vacation?" She asked slyly.

He grinned, and the fact that he looked like he knew something more, was very disconcerting. "A... vacation?"

"Yeah." She said confidently. "I need one. You have the money. All I want to do is hang out by the pool and eat whatever I want. With the lovely thought of you paying for everything"

He chuckled. "About that. I need you to stay in the room. At all times."

Her eyes widened. "What?"

"See, Coach doesn't really like it when we bring people along with us. It's sort of a team only gig. So I need you to stay put."

"For the whole weekend?" He had to be joking. He just had to be. Surely he couldn't be serious.

"Yup."

She stared at him in disbelief for a good five seconds, before she picked up her bag and headed for the door.

"But if you do stay, I think we can work something out."

She stopped, her hand on the doorknob. Knowing she was going to regret this, she turned around slowly to face him. "Like what?" She asked in suspicion.

His grin was just too smug for his own good. "Like, what if I help out with your rent for the next month?"

Ah! yes. The devil always tempts the innocent with something they badly need. "Two months." She bargained. It would be nice to spend money on a new wardrobe for a change. And the missing five books to complete her encyclopaedia collection. She misses that new book smell.

He shrugged. "Two months." He said casually without a second thought.

She glared at him. "Fine. I will stay the weekend."

"Aww, Case. I think that's the nicest thing you've ever said to me."

Continuing her murderous glare, she put down the bag. "Don't get used to it."

He grinned. "Oh, I know this is as good as it gets. I actually have to leave in a few minutes for a meeting with the coach, so lets discuss how to sneak in food for you so that you don't have leave the room for the next two days."

Word to the wise, getting your step-brother to squeal 'ow' after a good punch, is extremely therapeutic.

In the twenty minutes she was left alone in the room, Casey McDonald had discovered several things that were well worth remembering for future kidnappings. One, her so called roommate will never understand the difference between morning and night moisturizer. Two, that very same roommate did not understand that when travelling, something more than shorts was obviously essential. And three, her to-be-dead roommate did not understand the difference between sleeping with a boyfriend and sleeping with an annoying, self-centered step-brother hell bent on making her life a living hell.

She continued to glare at the barely there night things that were squashed unceremoniously into her bag. Forget the fact that it's hugely inappropriate to sleep wearing only that, unless you have gone beyond third base with a special man-friend. Forget the fact that it was another reminder that she has yet to go to third base with her current man-friend. And forget the fact that he still hasn't called her in a panic wondering where she was. How could her roommate carelessly stuff a silky garment into her bag without folding it the right way, as she has shown her countless times? There's a procedure to folding for a reason.

With a sigh, she pulled out the crushed, green and black silk garment, and held it out to assess the damage. Figures that Derek would walk in then.

"Whoa! Case! I think you got the wrong idea here. I mean, I know I'm irresistible but-"

Sporting a deadly gaze, she tossed her nightie towards him, which he caught easily in amusement. "I think Susan packed that for you." She pulled out her camera. "She wanted me to take pictures."

Derek looked oddly impressed. "Kinky."

Rolling her eyes, she went back to trying to figure out exactly what she was lacking during this most atrocious weekend of her life. "Go ahead. I bet it's your size."

"If you're hinting that I'm into sexy, slutty things...then you're half right." Tossing the nightie back to her, he headed towards the closet. "I came to tell you the good news."

Curious, her gaze fell on him as he pulled out his hockey gear. "Your game was cancelled?" She asked, her tone hopeful.

"No." He said calmly as he slung the bag over his shoulder. "We're going to check out the rink for a few hours. Get in a good practice before the game tomorrow."

Her eyes widened in surprise. "You mean I can get out of this room?"

Derek looked thoughtful for a second. "As long as you duck when you see Cooper, sure." Heading towards the dresser, he grabbed his keys.

"You don't trust me with your car keys?"

Tossing it effortlessly before catching it and slipping it into his pocket, he grinned. "Nope."

She decided to ignore that remark. It wasn't anything new anyway. "And why isn't Cooper going with you?" She asked curiously.

Derek shrugged way to casually. "There was a fight. Coach benched him. Now if you don't mind..." He picked up his sunglasses and put them on. "...I've got a puck to hit." With a cheesy click of his tongue and a fake shooting gun signal, he was off. She rolled her eyes in annoyance. Yeah, he's an idiot.

As soon as Derek left, Casey set about making a list of things that had the dual effect of entertainment and high cost that she could put on her step-brother's bill. Unfortunately, what she didn't expect was for her to be so tired, a little 'relaxing time' on the bed to end up as a full fledged nap. Which is how her step-brother found her. On the bed with her arms cuddling against a pillow. And the way he woke her up? Not so considerate.

"Wha!" She groaned as she sat up, her hand immediately going to her head where she felt something soft hit her.

Derek, with the smirk of the century on his face, looked at her in mock concern. "Oh, your up. What good timing."

She narrowed her eyes at him through her messed up hair. "Yeah, imagine that. Me waking up just when you wanted me to wake up."

"The world is crazy like that." He crossed his arms and eyed her in amusement. "So, you used the no-hockey-player down time well?"

"What?" She was groggy. She could be confused if she wants to.

With an arrogant strut, he walked over to the windows and pulled back the shades revealing a very dark view. "We were gone for four hours. I thought you would be lounging near the pool, ordering God knows what, and I find you here, asleep, and not spending my money." He finished with a wide grin.

She just stared at him. Then her gaze winced at the clock on the bedside table. "Four hours? I missed four hours?" Groaning, she fell back on the bed. Unsatisfactorily not ignoring her annoying step-brother's snicker. "Shut up." She mumbled through her hands that were covering her face in shame. Because that was what she was feeling. Shame for being so predictable.

"I'm so happy you care about me so much, sis..." She spread her fingers to glare at him for using such rude language, which only made his grin widen. "...but I need you to get off that bed and entertain me."

She scoffed. "Entertain you?"

He gave her a very 'duh' look. "Uh...Yeah. I have an hour before dinner. So..." He clapped his hands together in expectation. "...what are we going to do?"

"I'll tell you what we're going to do. You're going to crawl back into the little hole you came from, and I'm going back to sleep." She smiled sweetly before turning her back to him and closing her eyes. She was still tuckered out. Getting kidnapped is tiring.

She felt the bed dip violently next to her as he jumped onto the mattress. "You're not getting rid of me that easily." Closing her eyes tighter, she pulled the pillow against her and sighed deeply. For a moment she wondered if Derek had given up on her. It took her a few minutes before she finally let her body relax, and snuggled further into her soft, comfy, pillow. And that was when it happened.

"Casey." He poked her. "Casey." Another poke. "Casey." And another. "Casey." Another. "Casey." Another. "Casey."

"What?" She snapped as she turned around to give him her award winning glare for threat of death.

"You sleeping?" That was it. With a tight grip on her pillow, she smacked him. Hard. "Hey!" He protested as she swung again. "I was just asking."

"Really?" She asked through gritted teeth as she struck him again.

He just chuckled as he kept her blows at bay. His arms skillfully blocking her. Damn hockey and it's stupid reflexes. Then, in a second, her pillow was in his hands. Gasping, she tried to grab the other pillow, which he successfully took right out from under her.

She puffed out an annoyed breath, blowing her messed up hair out of her face. "Why won't you just let me sleep?"

He raised his eyebrows at her. "Because you're here to entertain me." He said slowly, like he was speaking to a four a year old.

"Honestly, you're a child." She huffed.

"And you're a horrible baby-sitter." He chided.

Her jaw dropped. "Well, you're awful at..." He looked at her expectantly. "...at...doing laundry."

His lips twisted in amusement. "And you're awful at not doing laundry."

She raised her eyebrow at him. "Really? Are you actually trying to argue that not doing laundry is better?"

He shrugged. "In a perfect world." With an eye roll she turned her back towards him and went back to trying to sleep, pillow-less. After about a minute of silence. "Pssst. Casey."

"What?" She snapped.

Another minute of silence. "I'm tired."

She let out an annoyed breath. "So?"

"So..." He poked her shoulder. "Sleep with me." He said in a mini whine.

"Ugh. No. Besides, don't you have to go for dinner in a little while?" .She could practically see his shrug in her mind's eye. "I just want a little nap."

"Go get your nap somewhere else."

"Fine." He huffed.

"Fine." She sighed happily and closed her eyes. She felt a moment of blissful rest before she felt his arm slide around her waist and unceremoniously roll her over until she was on her back. "De-rek." She screeched. But it was too late. Her tentacled step-brother had already landed on top of her, his arms holding onto her tightly as his head fell on it's usual place on her shoulder.

"Shhh, Case. I'm trying to sleep." And then he had the audacity to snuggle against her as he got comfortable. Granted, she was not at all uncomfortable but...that was hardly the point.

"Derek-"

"Rent." He whispered softly, his grip on her slackening. She felt his eyelids flutter close softly against her neck as she ignored the tiny tingle that went through her from feeling his breath slow down against her. She let out a sigh as she gave in, her thoughts settling on the slightly wet hair of her step-brother that tickled her chin. Thank God for showers at the hockey rink. At least he didn't stink of sweat and God knows what else. Their breaths fell into a matching rhythm, just as it always did, and Casey found the situation soothing against her will. Within moments, her own eyes fell shut due to pure exhaustion. She just had one last thought before she fell into a blissful sleep.

This thing between them, it's normal. Honest to God, it's not weird. Really.
