Disclaimer: I don't own Life With Derek, Casey and Derek would be together if I did.

Casey was in her bedroom getting ready for a date with Max. She was just putting on her mascara when Marti came in, sat on Casey's bed and looked in wonder at the containers on the vanity.

"Hey, Casey! Wanna play?" Marti asked.

"Oh, I'd like to Marti, but I have a date in 15 minutes with Max." She replied, putting down her mascara wand and picking up her lip gloss.

"Oh, well, okay." Marti said, disappointed.

Casey looked at the reflection of the girl on her bed, she turned around to look at her. "Well, I can put some makeup on you if you want." Casey offered.

Marti instantly brightened. "Okay!"

Casey had to laugh at the youngest Venturi, she got up from the bench. "Okay, sit down and face me."

Marti was bouncing on the bench as Casey picked out some makeup she could put on her stepsister. Casey muttered as she examined the bottles on her desk. "Too dark, wrong color, perfect!" She started applying the eyeshadow lightly to Marti's eyelids, once finished she picked up the mascara and put a thin layer.

"Casey, where are you going with Max?" Marti asked, kicking her legs.

"Uhm, we're going to a movie and going out to pizza." she answered, smearing some of the shadow off.

"Oh, I wish you could stay home tonight and watch a movie with me and Derek."

"I don't think Derek would want me there."

"Yeah he would."

Something in Marti's voice made Casey pause and look at her. "Did he say he would?"

"I think you and him would get along more if you spent more time together."

"Think so, huh?" The thought of them getting along wasn't as impossible as Casey thought it would be. She thought he was sweet at times when they had moments they actually got along. Maybe she didn't hate him as much as she said she did. Maybe-

"Casey, are you okay?" Marti asked breaking her out of her thoughts.

"Huh, oh yeah I'm fine, I'm just thinking."

"About Derek?"

'This kid is good, scary good.

"Uhm, well-"

"You like him don't you?" she asked, staring up at her older stepsister, knowingly.

Casey paused.

"Its okay I don't think he knows, its just you get this look whenever he's around or you talk about him."

"Do I? Is it really that obvious?"

The little girl just shrugged. "Sometimes."

'Oh great if its so obvious, then who else knows?'

Silence followed as she finished putting a layer of her favorite lipgloss on Marti. Then heard a distant slam followed by ''I'm home, Edwin, Jacket." "Coming Derek."

They heard footsteps on the stairs and then Derek peeked in Casey's room, Casey put down the lipgloss. "Hey, what are you doing?"

Before Casey could answer, Marti broke in. "Don't I look pretty, Smerk?"

Derek grinned at his sister. "Beautiful, Smarti."

Marti had an idea. "Like Casey?"

Derek paused, glancing at Casey. "Yeah, just like Casey." He said, softly.

Casey looked at the ground, blushing pink. Marti saw this was the time to go. "I'm gonna go put on my princess dress to watch the movie." she ran out the door, grinning.

"Do-Do you mean that, Derek?" Casey asked, timidly, biting her lip.

Derek took a deep breath and looked in her eyes. "Yes, I do."

They stood there, smiling at each other until the doorbell rang, snapping them out of their thoughts.

"Casey, Max's here!" her mom yelled.

"I guess your not staying for the movie with us?"

"Well, do you want me to stay?"

He stepped up to her, looked deep in her eyes, cupped her chin in his hand, and kissed her. She quickly returned the kiss before they broke apart.

"Does that answer your question?" he answered, smirking. She almost melted on the spot. How she loved that smirk.

"Casey?!" her mom yelled again, coming up the stairs. She came across the two of them in each others arms. "Finally." she smiled, causing them to break out of their moment.

"You mean, your not mad?" Casey asked.

"No, I knew this would happen, it was so obvious to everyone."

The pair blushed.

Nora smiled. "I'll leave you two alone."

"What about Max?" Casey asked, worriedly.

"I'll tell him your sick, and you'll call tommorrow."

"Thanks, Mom."

"Yeah, thanks Nora."

She just smiled, walking out of the room, down the stairs to the awaiting family and the now ex-boyfriend.
