SiscoKid: Well well well. Never thought I would write a Life with Derek fic but here one is.

Derek sat at the couch in the living room. It was late or early in this case. 12:35 at night yet him and Casey were still up. It didn't matter much because of the fact that it was a Saturday night. Casey was up putting the finishing touches of a chemistry project together while Derek on the other hand sat flipping mindlessly through channels on the T.V. But he wasn't really watching T.V. His eyes were fixed on his stepsister. Incest thought flowing through his mind bring him to the brink of frustration. 'Why the hell does she have to be my stepsister?' he asked himself as she wrinkled her eyebrows at a problem that must of just arised on her project.

'What am I talking about! Even if we weren't related in anyway what so ever, she still would never as much give me a second glance. I have a better chance with Emily anyday of the week.' Derek thought's came to a hault because of the other ocupant in the room.

"Hey turn it back. I like that song!" Casey demanded.

"Well I don't." Derek replied boredly even though it was one of his favorite songs.

"Come on. Its not like your watching anything anyway." Casey pointed out eyes still glued to her project.

"It doesn't matter. I'm not going to listen to a song I don't like." He said bluntly still flipping through channels.

"Well it must not of been you in your room when I heard this song playing. Oh and it must not of been your voice either singing to it." Casey retorted. Smiling on the inside because she knew she had won this fight.

"I guess not." Derek muttered. Quite shocked that she had heard him singing. 'I thought nobody was home when. I swear she was staying after school for one of her dorky clubs.'

"Its wasn't you then I see. Then I guess your brother got home from school early, unlocked your door and gain the singing voice of a teenager." Casey stated blandly while rolling her eyes.

"Whatever!" Derek huffed frustrated that his mind was a mass of aggravation at the moment and Casey wasn't helping. Hell her just sitting there sat his teenage hormones on fire.

Derek changed the channel to the music video and decided it was time to go to bed or as far away from Casey as he could get. Which was rather hard since they lived in the same house.

"Why are you leaving? I already know you like this song, you can drop the act." Casey said looking up from her project to him.

"I grow tired and if I don't get enough sleep, I won't have the energy to make your life a living hell tomorrow." Derek explained as if she should know this already.

"What! I woke up at seven o'clock this morning. You didn't crawl out of your cave until twelve. I'm not even tired yet." Casey replied.

"Oh Casey. How shall I explain this to you. I am a human or Homo sapien to be all scientific like you. Like all human I require sleep and lots of it. Unlike you I am not a robot who only needs three hours of sleep everyday." Derek explain in a sophisticated voice. He slowly took steps up the stairs.

"That's not true. I get as much sleep as I need. You just hibernate." Casey argued, starting to get a little angry.

"Bull, then tell me who's this. Oh I got a project that's due in three weeks I'll just do it all tonight like some nerd with no life what so ever who's worried their four point o will be destroyed by one project." Derek replied a bit cruelly, nearing the top of the stairs.

"That is not me." Casey said with a hurt expression splashed across her face.

All the frustration in Derek melted away as he stared at her from the top of the steps.

"Look I'm sorry I didn't have to be so harsh." He apologized sincerely.

Casey looked at him in disbelief. "Did you just...apologize. To me?" She asked.

"No." Derek replied shortly before turning and walking to his room.

"He just apologized to me." Casey told her self with her hand placed over her racing heart.

SiscoKid: Okay this story came out of nowhere I just sort ah started typing it out of well nowhere. I may just leave it as a oneshot since it could actually be that. But if some people want me to continue I guess I can since I'm on summer break and time is not a matter at the moment.
