"Hey, Casey!" Emily greeted her at the door, prom had started and Jesse's arm was planted on the small of her back. Her friend grinned at her and led them over to a table where she and her date Joey-Something were.

Jesse remained standing, "How about I grab us some punch?"

She smiled up at him, "Sure."

"See you in a few." Casey watched him go. When she looked back, Joey was playing a PSP he was hiding just out of view of the prom goers.

Emily looked at her expectantly, "So?" Casey raised an eyebrow and Emily rolled her eyes, "How's plan 'Get-Back-Sam' going?"

Casey sighed, "He barely noticed I walked in. Very few guys noticed. Only Jesse and Derek had any reaction at all. Thing is Jesse is really nice."

Emily blinked at her, "Derek?"

"Hwat? Oh, all he did was stare like I'd grown a third head. That's more than I got out of Sam. We walked right past him outside. It's like I wasn't here."

"But wait, how did Derek stare at you?"

"Like this." She then made an exaggerated state of shock.

"Are you sure that was the look?"

"Okay maybe it wasn't that but it was close." Emily sat there for a minute without saying a word causing Casey to grow anxious, "What is it?"

"Well, I just thought of something... About Derek and Jesse. Jesse had been... I don't know what you'd call it. His rival? It seemed Jesse was always keeping an eye out for ways to one up him. Jesse usually knew what Derek wanted even before Derek did and he made sure he got it first. But that doesn't mean anything... I mean. Jesse moved away a few months before his dad married your mom."

"What's that got to do with anything? So Jesse use to be a little childish? He's changed."

Emily dug her nails into her palms, nervously, "It's probably nothing... But-"

Casey smiled, "Emily, if there was still some bad vibe between them he'd be going straight for Sally. So don't worry so much."

Emily gave her an unenthusiastic smile, "I'll try."

Jesse returned with to cups of punch, "One punch for you, milady."

"Thank you, Jesse."

...

"I can't believe him." Derek glared into the dance hall at Casey and Jesse. Sam took a long drag of his cigarette causing Derek to shoot him a look of disgust. "That's really gross, man."

Sam blew the smoke out of his nose, "Yeah, I know. But you're one to talk."

Derek raised an eyebrow, "How so?"

"I'm perfectly fine with her being here with our nemesis from the old days and I'm her EXBOYFRIEND. What's that say about you?"

"You're totally okay with this? I mean, I know you broke up with her but you two have been on and off for over two years. I don't even know why you broke up with her. Was it another girl?"

"No, that would have been easier... There was something between us. Something that I couldn't ignore anymore."

"What is that?"

"She wasn't in love with me anymore. This trying to make me jealous thing?" He gestured to the prom with a sigh and took another drag, "It's her trying to salvage the last of our relationship. Which is why I'm not mad. She didn't do it on purpose. But I couldn't live the lie anymore. We were just playing house."

"So her being here with Jesse doesn't bother you at ALL?"

"He's using her Derek. And you'll find that out all to quickly. Uh oh." They watched as Jesse led her off the dance floor and out through a door. "Better go get her. I'll talk to Sally and explain." Derek was already gone.
