GOOD TWIN, EVIL TWIN

AUTHOR'S NOTE/DISCLAIMER

I've seen other fics that has Casey with a sibling that's nothing like her, and I thought I'd give it a shot. The first chap takes place a little before the "The Room", and then will take place in the current season. I've changed Casey's relationship with her dad somewhat, and Dennis' character is completely different, so the episode "Guess Who's Coming To Dinner" never happened. Life With Derek belongs to Canadian Television and Disney. I only own the plot.

The party was in full swing and kids were talking, laughing, dancing, and making out. Casey MacDonald finished up in the bathroom and headed back downstairs. This wasn't really her type of scene, but her brother had begged her to come, and like always, she had caved. Suddenly, someone grabbed her arm. She gasped.

"Hey, sorry. I didn't mean to scare you," a voice apologized.

"Oh, it's okay, Kurt," Casey responded.

"Let me make it up to you," Kurt Parks requested, leaning into her.

"Uh…Kurt…what are you doing?" Casey questioned.

"Relax. I know you've been sending me signals: smiling at me, being nice…" Kurt let the sentence trail off as he ran his fingers through her hair.

"The keyword being 'nice'. I'm nice to everybody," Casey reminded him, trying to pull away.

"Well, you've just been a bit nicer to me than anybody else," he stated, as he grabbed her and began to undo her top buttons.

"Actually, no I haven't," she retorted, once again trying to pull away. He pulled her close and kissed her roughly. The girl struggled, and then pushed him. He toppled backwards in an upward position, and Casey ran back downstairs. Meanwhile, Casey's twin brother, Nick, was walking around aimlessly when he saw her running up.

"Hey, what's wrong?" he asked, seeing her upset demeanor. Then, noticing her unfastened shirt, "What happened?"

"Nothing. I'm fine," Casey lied refastening her shirt. She started to move past him.

"GT…level," Nick insisted, grabbing her arm. "Did somebody hurt you?" he questioned. At this, Casey's face crumpled. "Who?" he demanded harshly.

"Kurt Parks tried something, but---" she trailed off as he headed in the direction she had come from. "Nick! Nick! Your probation!" she warned, pulling on his arm.

"Screw my probation," he growled, yanking free. He continued, Casey at his heels. Presently, he found his quarry.

"Nick, what's up, dude?" Kurt questioned. With a growl, Nick tackled him.

"Nick!" Casey exclaimed.

"Dude, what is your problem?" Kurt wondered, blocking the oncoming assault.

"You think you can try to rape my sister?" Nick demanded.

"Dude, that was just a misunderstanding," Kurt stated. He threw the other boy off of him and started throwing his own punches. The other kids quickly moved out of the way as they both stood up and began moving about. The fight ended when Nick threw a punch and knocked Kurt into a closet door. He moaned and slid to the floor. Minutes later, police and their parents were there. After hearing what had happened from Casey and a few others, Nick was placed under arrest for aggravated assault and parole violation and placed into a police cruiser. A few weeks later, the MacDonald family was in the center where prisoners waited before being transported to prison. Nora stared in shock at her husband, who had just said that he was signing full custodial rights of Nick over to her as part of the divorce, though he still wanted to see Casey and Lizzie.

"Dennis, you can't be serious," Nora MacDonald said.

"Oh, I am, Nora. This little stunt of his was it! I've had it with him!" Dennis MacDonald shouted. "I'm done!" he declared.

"Dennis," Nora said in surprise. How could he just give up on Nicky like this? Especially since he had just been defending Casey.

"No, I mean it. I've had it, Nora. The little punk's screwed up for the last time. I want nothing more to do with him," Dennis continued.

"Gee. Love you too, Dad," Nick deadpanned. Dennis reached out towards Casey who stepped away and took her place beside her twin. Lizzie just stood beside her mother, not even looking at their father. She wasn't sure what caused Nick to act like he had, but she didn't like her father's attitude. The man just scoffed and walked out of the facility. Nora, Lizzie, and Casey stared at the boy.

"You okay, ET?" Casey asked.

"I'll be all right. I made the mistake…I gotta pay for it," Nick responded.

"Well, when they let you out, our home is your home," Nora told him.

"Thanks, Mom," Nick responded.

"Okay, time to go," the guard told them. The girls walked out. Casey looked back to see her twin holding his left hand up with his second and third fingers intertwined. With a sad smile, she did the same, only with her right hand. Then, she walked out and the door shut behind her.
