A/N: I apologize that this is short, it was suppose to be longer, but I was writing this and trying to write two papers, oh I love college, at the same time, X / What was the rest of this is now ch. 5, which will be up next Sat.

Disclaimer: The same as last time, and always will be

For Casey and Derek, today was the same as every other day. Derek would pull a prank on Casey and in turn, she would get mad and confront him. Insults would be thrown, and then Casey would mention how Derek has changed so much from when they were younger. Derek, who has always maintained that he is not Casey's best friend from her childhood since the rehearsal, would get madder and reinforce this yet again causing Casey to become even more frustrated. All of this ending to name calling, stomping and slamming doors.

Casey, tired of this, just wanted to get to the truth but so far she has had absolutely no luck. Derek constantly denying it; her mom and George constantly avoiding her questions; the kids just telling her to drop it; and Emily who apparently doesn't know everything about Derek, like she thought she did, was as clueless as Casey. The one person Casey had yet to ask was Sam. And asking Sam was exactly what Casey is doing at this very moment.

"Why would Derek deny it?" Sam asked confused as to why Casey had taken this long to ask him about this, of course Derek has complained some to him and Casey has complained to him, herself, about this some but she has never tried to ask him if he knew anything.

"I don't know that's why I'm confronting you" Casey said exasperated. She felt like she's had this conversation a million times over already.

Later that Day

After getting home from Sam's house, which proved to be utterly useless, she stomped up the stairs and barged right into Derek's room.

"What do you want? What don't you understand about 'leave me alone'?" Derek asked as he looked up at Casey from his computer screen, annoyance clearly written on his face.

"Does Sam even know you?" Casey simply asked, ignoring Derek's attempt to get her to leave.

"Of course he knows me. He ismy best friend, Case." Derek answered seeming to forget that he had just asked Casey to leave him alone just about a minute ago.

"Well apparently he doesn't" Casey stated matter of factly, contradicting Derek.

"Really and how did you come to this conclusion?" Derek asked slightly amused and slightly intrigued about just how his dear stepsister came up with this.

"Well, I wanted to ask him if he knew, maybe, anything…about 'your past'" Casey answered not exactly sure if it was good idea or not.

"WHY? Do you keep on insisting to but into my life, can't you just let it go. I told you, I'm not your ex-best friend, for the last damn time!" Derek yelled, throwing his hands up in the air.

"Well sorry if I just wanted to get to the truth." Casey replied stubbornly to Derek's outburst, before walking out of the room and slamming his door behind her.

All Derek could do was push his chair back slightly, slouching with his head in his hands, while his elbows rested on his thighs and sigh, before turning his attention back to his computer screen.
