Emily knocked on Casey's bedroom door ten minutes later and Casey let her in.

"Hey." Casey said, still frustrated. Emily closed the door behind you.

"Don't let anything Derek says get to you. You know he doesn't mean it the way you think." Casey said nothing and sat on her bed. Emily sat next to her. "It's just he doesn't know how to say it to you. He won't admit it but I know he's intimidated by you." Still saying nothing, Casey looked at Emily. "I bet you won't believe it either, but it's more obvious now to me than anything." Casey furrowed her eyebrows at Emily. Em, don't you admit what Derek needs to admit. Don't… "With all the time I've spent with Derek, as friends, lately…" Casey looked away and scratched the back of her neck, "I've gotten to know him really well. I think having a real friend that was a girl helped him get in touch with the side of him we know is in there." Emily put a hand on Casey's shoulder. "I know you know it's there too. I'm the observer. Remember? I know what you see."

"I guess spending time with Derek has also made you a little more arrogant." Casey said with a smirk on her face.

"Hey…" Emily nudged her. "Well I guess we all rub off on each other eventually."

Casey laid back on her bed and Emily looked down at her.

"Are you nervous?" She asked innocently. Casey glanced at her.

"About what?"

"Sneaking out. Breaking the rules. Derek said that you were going to sneak out too." Casey sat up again.

"Well, he practically shoved that answer down my throat. And I guess I never rejected the idea," Casey pointed a finger at Emily, "But I never said yes." Emily nodded her head.

"Normally, I think I'd just say stay at home like you were told, not that you wouldn't obey your mom anyway, but this time…" Emily looked deeply at Casey. "I think you should go."

An hour later a knock was placed on Casey's door, then the figure she knew was Derek opened before she could answer.

"Time to get ready. We're going to leave in about ten minutes so get your concert-head-banging outfit ready ladies." Derek held up a rock on sign and stuck out his tongue. He shut the door and Emily grabbed her plastic bag that held clothes in it.

"Is that what you are going to wear?" Casey eyed the cleavage and midriff showing blood-red tank and black skirt.

"Yeah. I got it from Trevor's twin sister. Even though me and Trevor broke up we are still good friends and because of that I got closer to his sister. She's into Coldspray that's how I got a good deal for two tickets." Casey raised an eyebrow.

"Just because she's into Coldspray doesn't mean she gets a discount." Em laughed.

"Well, yeah, but she works at the radio station on weekends. And they gave her four tickets for cheap, and I bought the two extra she had off of her." Casey nodded her head. "What are you going to wear?"

"Surprisingly, I never actually figured that out ahead of time." Emily got up without a word and started going through Casey's closet to find clothes for her to wear.

The end result was the black shirt she wore when she was babe raider for a presentation, a grayscale plaid skirt, netting on her legs and boots from the bet she had with Derek over Trevor.

After a couple more minutes of them putting on their makeup, they headed down the stairs and saw Derek and Sam talking in what appeared to be a serious manner.

Casey was taken back because it was rare she saw Derek with a serious face.

Derek glanced up at Casey and his eyes couldn't help themselves but travel from her ankles to her eyes. She smiled at him with a hint of flirt.

"Ladies, you look good!" Sam exclaimed. Emily smiled a little extra at Sam. His eyes averted slightly and Casey could tell a little flirting was going on between them. When Emily and Casey were in private again, she would have to ask if there was anything she felt for Sam.

"Come on senioritas, we have an el concerto to go to!" Derek said emphatically, gesturing to the door. Casey smiled at Em, rushing with excitement and laced an arm around hers, then followed Derek out to the car, finally leaving Sam with the kids.
