Disclaimer: You know. I do not own Life with Derek. All I own are my stories.

A/N: Okay, so I realize that it's probably not very realistic how Casey's eating disorder is being treated, but that's how they handle it in the book 'Perfect' by Natasha Friend. Please read and review afterwards. I'd like to hear what you think and so far only a few people have shared their opinion.

Chapter 3… Who Is She?

After the session, I stood outside in front of the building in the cool autumn breeze waiting for my mom to come get me. My head was pretty blank as I stood there, watching a tree's leaves rustle in the wind.

"So… Casey…" I heard a voice say behind me. I turned to see that pretty girl, Amy, wearing a small smile, hands in her sweater pockets, looking at me like you'd look at someone who you've known since you were a kid. "What grade are you in?" she said in an obvious attempt at conversation.

"Ummm…" I said stupidly, looking down at my shoes, "Tenth… You?"

"I'm a senior," she said, confirming what I already knew because I had peeked at what she'd written on her card.

"Oh. Cool," I said lamely, not knowing how to respond.

"Listen," she said quickly after. "I know you've probably heard of me before, but no matter how bad my rep is, I just… I was hoping you could keep this between you and me. Would that be okay?" She actually looked slightly nervous. Rep? What rep? I don't exactly subscribe to the imaginary gossip column at our school, but I still liked to think I knew the biggest rumors. And I could honestly say I knew nothing about hers.

"Okay," I answered, trying to keep the confusion from showing in my face. I heard a car pull up behind me and looked over to see My mom, looking past Lizzie who was in the passenger seat, and motioning for me to get in the car. "Well, I gotta go."

"I'll see you at school tomorrow, 'kay?" Amy called out.

I turned to see her smiling her big smile at me and I called back, "Okay."

"Hey Casey," a voice said, close behind me. I turned around to see Amy standing there where Emily would be standing, had she not been sick today. "What's up?"

"Nothing, really," I said, feeling the awkwardness of the situation get to me. I mean, if her rep is as bad as it might be, I don't know if I want to be seen with her.

"Well I was wondering if you were doing anything today after school? Maybe you could come over," she said, smiling.

"Oh," I said, taken aback. I mean, she was so beautiful and she was asking me, Casey MacDonald, to come over to her house after school. "Uh…" But I didn't get a chance to answer because I heard a male voice from behind me that I knew all too well.

"Hey, what's up?" I heard Derek ask, his eyes on Amy, looking her up and down.

I rolled my eyes and said, "Excuse my stepbrother. He's a pig."

Amy laughed. "It's alright," she said, glancing over at Derek, in, surprisingly, disgust, "I deal with even worse all the time."

Derek had this shocked look on his face, much like the look two nights ago, but this time he actually spoke, "At least I keep my food." He looked at me. So this was how it was going to be from now on. I glared at him.

"So…" I heard Amy say after a few seconds. "Can you come over or what?"

"Yeah, sure," I said, turning away from Derek.

"Wait a second," Derek said, just as I saw Amy open her mouth to say something. "You're asking to hang out with Casey? You must be crazy."

"Not exactly the way to get to my heart pretty boy," she said, tilting her head. I couldn't help it. I cracked a huge smile. Amy turned to me, flashing a smile as well. "So I'll see you later," she said, biting her lip and turning away from Derek and I, not even giving Derek a second glance.

Derek looked over at me angrily. "Who is she?" he asked.

I turned back to my locker. "Amy something… Why?"

"Amy… I think I've heard of her…" Derek said, his eyes rolled to the corner of his eyelids, as if trying to decipher memories. "Oh yes," he said, a big, proud smirk on his face ", the lesbian party girl."

I froze, turning to look at him for a second. "What? Where the hell did you hear that?"

"Casey, you better watch that foul little mouth of yours. Could get you into a lot of trouble. Oh wait, it already has!" he finished, still smirking widely, leaning against Emily's locker.

"Shut the hell up Derek and answer my question," I said, furiously scooping up the books I needed for English.

"Surprising. I guess you really aren't that smart," he said, beginning to turn around to walk away.

"What's that supposed to mean?" I said quietly to his back.

"If you were as smart as everyone thinks you are you would have figured out about Amy long before now," he said, just as the bell rang. "Oh, better get to class now Casey, don't want to lose a percent for being tardy," he said in mock worry.

I just huffed angrily and walked as quickly as I could. Oh the things I'd like to do to shut him up right now… I thought.

A/N: Lol. It's really not what you're thinking. Or maybe it is. Better read on to find out…
