A/N: Yay! I'm updating AGAIN! Now you should be uber proud of me! I know I am. Okay, this chapter is shorter - but it's lots of fun - and the one you've all been waiting for! Okay. Go. Read. Review. Please!

Disclaimer: I do not own Life With Derek, it's characters or any references I may have made (Love Actually -and if you've got no clue - don't worry about it. Or ask me).

Looking up the stairs almost in horror, Derek tried to breathe, and he gulped nervously. All at once he started bounding up the stairs and ran until he got to Casey's door. He stopped himself from pounding on the door right away, and instead ran a hand through his hair. After taking a minute or so of deep breaths, he knocked lightly on the door.

"C'min." Shocked that she had actually let him in and that she didn't ask who it was, it took him a second to register what she had said. Moving as if in slow motion, he turned the doorknob, and pushed the door open. She was sitting on her bed, and didn't look up from her book as she stepped into the room. When Derek snapped her door shut she looked up, having finished her paragraph and placed her bookmark.

As Casey looked up her eyes opened wide, her mouth dropped open, and she scrambled back toward the headboard. "Don't say anything. Please." Derek stopped whatever she was going to say, and she nodded her head, willing to hear what he had to say. "I - I'm sorry." Slowly he started walking towards her bed. "I shouldn't've kissed you."

"Damn right you shouldn't've!" Casey was silenced again with a pleading look from Derek.

"But I don't regret it."

"You don't?"

"No. I - "he sat on the edge of her bed opposite her."I like you."

After Derek's exhale and a silence during which he studied Casey's face for reaction she said, "You - like me?"

"Yes. And don't ask me what type of 'like' I mean. You know and I know so we can skip that whole step." his tone was cocky, and she almost had to stop herself from smiling. He waited for her to say something, but she was still staring at her toes in shock. "Oooo - kay. Next step. You kissed me back."

That broke the trance, "Did not!"

"Yes, you did."

"Fine, I did. But I pulled away really fast."

"Would you be willing to do it again?"

"Do it? Again? Are you on crack?"

Derek laughed at that, "No. Can you honestly tell me that you don't want to kiss me again? You don't want to see if you felt anything - maybe you could tease me because you think I'm a bad kisser?" He raised his eyebrows at her persuasively, "The possibilities are endless."

Casey looked down at her nails thinking about what he said, not realizing how close he had scooted to her gradually; until he kissed her suddenly that is. She didn't think, even when she realized it was Derek kissing her; all she did was kiss him back. He actually broke the kiss, and whispered to her, "You kissed me back."

"I know. Point?"

"I forgot." He kissed her again, and this time she wrapped her arms around his neck and with his arms around her waist he pulled her closer. Neither thought and they both conveniently forgot about everything else when they came together again after that.

Derek simply smiled and told his Dad that his 'problem' had worked out when he asked. And after Casey broke up with Sam she simply said that they had grown apart.
