Before Emily could stop her, Casey marched over to where Chrissy was still kissing Tristan, who by this time had overcome his shock and was in the process of pushing the girl away.

"Hey, James," she greeted, pulling the other girl away. Then, she put her fingers in his hair and started tousling it.

"You forgettin' I'm a James?" he queried.

"Maybe this Mary wants this James," she told him, tracing a cheekbone with a finger. He chuckled and leaned upward so that his mouth was near her ear.

"Game on, huh?" he whispered huskily.

"You know it," she murmured. He kissed her neck and she sank down into his lap. Then, they started kissing passionately. Someone cleared their throat and the two broke apart hurriedly.

"Hi, Principal Lassiter," Casey greeted nervously.

"Casey MacDonald. Why am I not surprised at your adolescent behavior?" he queried in disapproval.

"Uh, Sir. It was my fault. This was my idea," Tristan interjected.

"Fine. I'll see you both in detention," he told them. Then, he walked away.

"Ooooh. Sorry, Mary," Tristan apologized.

"I'm not. I'll show that little public school Magdalene what it's like to mess with a private school Mary," Casey declared, her eyes flashing. Tristan chuckled.

"Oh, I don't pity her," he commented as the girl took his food and began eating it. Casey was only able to get in a few bites before they had to go to class. With a groan and a final bite of food, she walked off, with the boy of her affections by her side. After school, Casey and Tristan headed for detention.

"Casey, what am I supposed to tell Dad and Nora?" Derek wondered.

"Tell them I had a situation with a Magdalene. Mom will understand," Casey replied. Then, before her stepbrother could respond, she walked away.

"How could she understand when I don't even understand?" he griped to himself, not noticing when Sam and Ralph walked up.

"Dude, what's up with Casey? She's totally not acting like herself," Sam commented.

"Yeah. She's gotten hot!" Ralph raved.

"Ew! That's my stepsister," Derek responded. Then, "Let's go. I'm gonna have a heck of a time explaining this to Dad and Nora," he sighed. Then, they walked off. Casey was assigned a desk in the front and Tristan was placed in the back.

"Wait right here as I go get the man responsible for you in here. Now, don't get any ideas. He'll be watching you at all times," Principal Lassiter told them. Then, he stomped out of the room.

"Is it just me or is he wound a bit tight?" Tristan questioned.

"Oh, it's not just you," Casey assured. They laughed, but fell silent when the man came back with the teacher assigned to watch them.

"Paul?" Casey asked in surprise.

"Casey?" Paul repeated in the same tone. What's she doing here? he wondered. It had to be a mistake.

"Um, Principal Lassiter, I think there may have been some sort of mix up---" he began to say.

"Not unless she tripped and fell on that boy's lips right in front of everyone in the cafeteria," the principal interrupted. Paul fell silent, but looked at Casey in surprise. Casey had been caught making out with this boy in the cafeteria? Casey had been caught making out with a boy in the cafeteria period? That didn't make sense. "Now I'll be back in two hours. In the meantime Mr. Grieby, make sure they don't break any more rules," he continued, and then stomped out again. Paul grabbed a chair and sat down in front of Casey.

"Casey is there something you'd like to talk about?" he asked.

"There's not much to say, Paul. Chrissy Summers made a move on Tristan, and I showed her that if she wanted a fight, she'd get one," Casey replied.

"Okay, um…but your clothes for the last couple of days---" Paul continued.

"What about 'em? Tristan likes the Fray," Casey stated. "Well, not as much as he likes the Cure, but…" Casey's voice trailed off.

"Casey, you shouldn't try to change yourself for a boy. I mean, look at what happened with Max," Paul pointed out.

"You and Max? You went from Sam to Max?" Tristan asked incredulously.

"How do you know about Sam?" Casey wondered, turning to face him.

"We got to talking and he told me," Tristan replied.

"Oh," Casey said. Then, "Paul. I'm not changing myself. I'm just telling Tristan that I'm interested in him. It's a private school thing."

"Yeah, after a couple more rituals…it'll be clear." Paul looked at the two in surprise and confusion. What exactly was going on here? With a sigh, Casey grabbed her backpack, took out her homework, and got started on it. Tristan let out a small laugh. His girl. But that's what he loved about her. That she was so dedicated to her studies, and she didn't care what anybody said about her. Paul watched as the boy stared at her. She bit her lip in concentration, and he groaned.

"So not fair," he complained. She chuckled and his jaw dropped. "You're doing this on purpose," he realized. She laughed again. "That's dirty, Mare. That's really dirty." Back at the MacDonald/Venturi household, Derek had just told them about Casey.

"She has detention because of this boy?" George repeated. Had he been wrong about him?

"Why?" Nora queried.

"I'm not sure. She used the name Magdalene when talking about a girl that tried to make a move on that guy Tristan, but---" Derek began to say.

"Oh, I get it. Game on," Nora interrupted.

"I don't understand," George said.

"Tristan and Casey are into each other, but someone tried to come between them and Casey showed that she was willing to fight for Tristan," Nora explained.

"Whatever. I'm going to my room," Derek said. Then, he ran upstairs. Two hours later, Casey showed up with Tristan by her side.

"Casey---" George began to say.

"I'll see you later," Tristan told her. They kissed and then he left. Casey turned to George.

"So, what's for dinner?"
