A/N: This is something I wanted to do for fun. I'll post more, but it probably won't be quickly. Enjoy!

Disclaimer: If I owned Life With Derek, Casey and Derek would've gotten over themselves a long time ago and they'd be together by now.

Defining Moments

Orbit

Considering the fact that Casey always says that Derek thinks the world revolves around him, she'd be shocked at how much of his time is spend thinking about her.

Queued

Right now, they're just waiting for their ques, looking for the clue that says that the other one likes (loves) them back.

Separation

She wouldn't tell anyone this, but when she heard that Derek was leaving for Spain the first time, her first thought wasn't about getting his recliner; her first thought was 'How am I going to live without Derek?'

Suppresses

Whenever Casey sees Derek with Marti, she has to suppress thoughts about how he would be around children with her eyes and his smirk.

Shirt

Derek would never admit this - ever - but when he saw Casey at school, wearing his shirt with a scowl on her face, his first thought was 'Hmmm, I gotta get her to wear my clothes more often...'

Bothered

"Would you just shut up?!" Casey cried, frustrated.

"Make me," Derek replied, a smug smirk appearing on his face.

Casey stopped, a smirk not unlike Derek's showing on her face as she said, "If you insist," before pushing him against the wall and kissing him.

Tolerated

Derek didn't flat out try to get rid of Casey's boyfriends because they made her happy; but as soon as even a hint of a tear came to her eyes, there would be more than hell for them to pay.

Ripped

When Casey saw Derek without a shirt on for the first time, her only thought for about five minutes was 'If that's what hockey can do for a body, I gotta go to his games more often.'

Translated

It took a while, but now, they know each other so well that they can tell what the other is actually thinking in a glance.

Job

It was possibly the first job that he actually liked (and was good at), but in a second, he quit it - for her.

Quarterback

He had never really minded football before, but since Casey started dating Max, he absolutely despised it.

Subtly

Lizzie could never understand how Casey couldn't see how Derek was jealous of her boyfriends; he was probably one of the least subtle people she knew, even when he tried.

Brothers

Even though she hated lying, she let her mother think that it was because Casey hated Derek was why she absolutely refused to think of him as a brother.

Shorts

He honestly hadn't been planning on spilling his juice over her outfit; but when she said that she was going out with Max, and he noticed her outfit (or lack of outfit), he knew that there was absolutely no way he was letting her loser-of-a-boyfriend see her like that.

Abort

Derek had never really feared anything before; but then what was stopping him from knocking on Casey's door every night, and telling her how he felt?

Repeatable

There was something so invigorating about their fights that made them want to have them over, and over, and over, and over...

Seemingly

They were quite open about their dislike toward each other, but that always seemed to slip their minds whenever he had a hockey game (she always secretly went to them) or she had a performance (he hadn't missed one since he started maybe-kind-of liking her).

Spells

She never noticed - and for that he was thankful - but whenever he saw her dance, he was completely spellbound.

Producer

Everyone else seemed to think that he did everything on his videos so that he wouldn't have to share credit with anyone else. The real reason was that there was no way that he was giving up time to stare at Casey for hours without having to worry about other people noticing.

Biography

Edwin might have been the only one (besides Lizzie) to notice this, but Derek had enough footage of Casey to make a documentary of her.

Obey

Derek was so used to ordering people around, that he was surprised (and more than a little grateful), when Casey told him 'no' for the first time.

Garble

"So, Case, my amazing girlfriend, what did you get your sexy boyfri..." was as far as he got, before he caught sight of the outfit that she wore just for him.

Controversial

One of the reasons they told themselves that it would never work between them was because of the controversy it would cause, only to realize that the controversy had passed long ago because they had been so obvious from the start..

Spray

One of the reasons that Derek got so close to Casey was so that he could smell her perfume; sometimes it would cling to him, and it would follow him for a long time afterward.

Health

No matter how hard he tried to deny it, he always felt sick whenever Casey was on a date with someone else.

Prevention

He knows that busting Scott may have been suspicious, but there was no way that he was going to let his gir- uh, step-sister get hurt.

Bits

Derek couldn't understand how Casey's boyfriends never seemed to put a lot into the relationship, but that might have been because they only saw parts of her; he, however, saw everything, and if he had the chance, he'd never let her go.

Academics

He was never big on education, but that changed when the McDonald's (okay, so just one McDonald) moved in.

Rationally

Usually, Casey would be trying to get them to think logically in a situation like this - their parents were still up, and if they got much louder, they'd definitely hear them - but when Derek started nibbling on her neck, she couldn't help but think, 'Screw logic.'

Borrow

Once they started going out, Casey got into the habit of 'borrowing' Derek's shirts so that she could sleep in them.

Beard

Casey thought thought that while Derek would look awful with a beard, he looked damn sexy with stubble.

Insulted

As hard as he tried, Derek couldn't bring himself to be insulted when 'The Fridge' said that "Another Venturi boy needs a McDonald girl."

Continuous

The first time that George saw Derek and Casey together, he began to wonder if he and Nora started something.

Misplaced

For as long as she lived, Casey always claimed that the bracelet that Derek had bought for his girlfriend was 'misplaced', and that she did not, in fact, hide it in her room until she could figure out a way to get rid of it.

Private

Derek and Casey thought that they were quite good at hiding their feelings from everyone; but when Aunt Madge, who had seen them together for a grand total of half a day, hinted that they should do something about their feelings, they began to re-evaluate their opinions on some things.

Actors

As much as Derek hates Max, he can't stand Noel even more; not only because he's a nice, smart, funny guy, but because he's practically perfect for Casey. And he really can't stand that.

Unrelated

Anyone who knew Derek and Casey for any amount of time were well acquainted with the fact that they were not brother and sister, but step-siblings. No blood relation.

Spies

While they did want their older siblings to be happy, Edwin and Lizzie admitted that they had ulterior motives for trying to get Derek and Casey together. Because when they did, the possibilities for blackmail were endless.

Bet

The only time that Derek lost a bet was when Sam bet him that he couldn't go without talking about Casey for a day. He lost within the first thirty seconds.

Patience

As patient as Paul usually was, he was getting very close to sitting both Casey and Derek down for a session, informing them that they had been in love with each other basically since they had first seen each other, and if they didn't do something about it now, he was going to talk to their parents about putting them in couples' sessions.

Fails

Dennis wondered how everyone in the family had failed - and continued to fail - to notice how every other word spoken by the oldest children were about the other one.

Outrage

Derek didn't know what angered him more: the fact that Scott was cheating on Casey, or that he was jealous of the scum bag because he was.

Bug

When the girls at school started getting a little too friendly, Casey insisted that Derek wore her butterfly necklace to inform his 'fans' that he was taken.

Deficiencies

Derek was absolutely convinced that he wasn't good enough for Casey, not knowing that she felt the same way.

Designated

"This is the last time I am the designated driver," declared Casey, after having been forced to sit through a 'rousing' rendition of 'Too Sexy,' sung by a completely smashed Derek.

Continent

George finally realized how hard Derek had fallen for Casey, when he thought it was required for him to send his son to a different continent to stop him from being distracted by her.

Order

The family had lived in chaos for so long, that the everyone got nervous every time that the day didn't start with one of Derek and Casey's fights.

Congratulate

While it was nice to get Casey to say that he was smarter than her, Derek wondered what it would feel like to get congratulations that she meant.

Egos

It was a mutual agreement that the Venturi men's egos had taken severe beatings since the McDonald women joined the family.

Gentlemen

She knew he wasn't a gentlemen, true, but she was more interested in bad boys anyway, despite what she frequently said.
