Summary: Gabriella's mom and Chad's dad get married, making them step-siblings. Gabriella has to leave her school and friends and move to Chad's school, East High. Troy Bolton, a.ka. Chad's rival, makes a wrong move and finds out how Gabriella Montez-Danforth doesn't take any crap. Chad's girlfriend, Taylor McKessie, warns Gabriella about Troy, but (of course) Gabriella has to be herself and stand up for everyone. Things might get a little messy.

Chapter 1—Figure this

"Shut off the damn light!" A grumpy Gabriella groaned as she hid her head under her pillow.

"Nu-Uh. We have to get to school." Chad, her newly acquired step-brother shouted from her door way with his hand beside the light switch.

"I don't wanna!" She protested.

Chad chuckled before doing the one thing that annoyed her the most. He flicked the light switch on and off repeatedly. "Ready to get up yet?" Chad smirked.

"You're not even my real bother, no offense, and you are still so annoying!" She complained as she hopped out of the warmth of her bed.

"I think I am liking my new job as "big brother." He teased.

"You are only three weeks older as I am! Besides, I can be one hell of an annoying little sister." Gabriella said as she pressed her side against her bedroom door, pushing Chad into the hallway. Once she slammed the door all the way shut, she changed into an outfit.

She picked out a pair of dark blue jeans, a red V-neck top, and let her ebony-colored hair fall in effortless curls down her back and shoulders. Only applying a small amount of makeup on her chocolate brown eyes, she was finished.

Picking up her bag from her oak dresser, she headed out the door. Chad meet her right once she opened the door.

"Are you wearing that to school?" Chad asked, giving her a look-over.

"Yeah. Why?" Gabriella replied, confused.

"Either put on an undershirt or change tops. There are many pervs at East High, especially Troy." Chad grumbled the last part with hatred.

Gabriella slammed the door shut and stalked to her closet and put an under shirt on beneath her red top. She opened the door again and Chad nodded approvingly.

As they walked to Gabriella's car she spoke up. "So what is your deal with this Troy kid? You said his name coldly." Gabriella wondered.

"Don't mention him. Just stay away from him and don't get on his bad side like I have. OK?" Chad demanded.

"Sure mister pissy pants!" Gabriella laughed as she slipped into the driver's seat.

Chad grumbled something before talking. "So how did you get a car like this?" Chad questioned, motioning to the deep red convertible.

"My mom got it for me last year for my 16th birthday. She said I deserved it for winning the scholastic decathlon." Gabriella replied shrugging.

"Oh Cool." Chad answered before pointing the way towards East High.

"Holy shit!" Some random girl exclaimed while running down the hallway, "Troy is whipping Chad's ass!"

Gabriella's head swung around when she heard this. Everyone was on his or her way to lunch but now people were rushing towards the fight. Her first day was not bad. She had been standing by her locker with her new friends Kelsi Neilson, a shy pianist and composer but she was really fun once you got to know her, and Chad's girlfriend, who was a really pretty African American girl and was really fun to be around. The trio of girls raced to follow the crowd.

When they reached the crowd of cheering teens they were flabbergasted at the scene. Who she assumed was Troy (It was the teenage dude that she recognized from looking at her up and down when she entered the school that morning.) had pinned Chad against the lockers and was throwing punches at Chad's stomach. The teen had shaggy sandy brown hair and looked to be very built, but challenges are always good for Gabriella.

This was her new brother, and she was not about to let some guy whoop his ass. She marched through the crowd until she was about three feet away from the teens. "Hey!" She screamed. Troy didn't even react but Chad turned to look at her.

"Get… Away… Gabriella…" Chad chocked out. His new sister was not going to get hurt, not on his watch.

"Why aren't there any freaking teachers around?" She thought to herself before glancing around to see teachers against the walls. Looks as if this Troy kid at the school on a string. The teachers looked petrified. They were scared to intervene. This kid had done this many times before.

She had been in many fights herself, but not for this reason. She had a zero tolerance for bullies and she was known at her other school for getting in the way of them. IN a split second she made up her mind.

She charged over to the two male teens. Grabbing the back of Troy's collar she twisted it around in her hand before thrusting her hand towards the floor, bring him down with it. The second he hit the ground she placed a sharp kick in his side. The gasps from the surrounding teens and teachers strengthened her. She guessed that no one had ever stood up to him, nonetheless a girl.

She felt her ass collide with the tile floor and it took her a moment to register what had happened. Troy had grabbed her ankle and brought her down to the floor. Thank God for fast reflexes, she jumped back up at the same time as he did.

Laughing to herself at the expression on his face, she was amused. She could read it in his eyes. He was astounded that he had been knocked to the ground by someone, but not just any someone. This was the same girl he though was hot this morning, the same girl who was a new student this year, and the same girl who was about to slap him.

Her palm collided with his cheek with a loud and abrupt pop. Once again, the crowd that had gathered gasped. She brought her foot up so it rammed into his sensitive area. She laughed out loud when he fell back to the floor, wincing in pain.

Spinning abruptly on her heel, she walked to where Chad was sitting against the lockers. Extending her hand to pull him up, she asked if he was okay.

"Yeah… I guess." He answered. Chad was still in shock. His new sister had just beaten up Troy Bolton.

The crowd started to disappear but some returned once they saw Troy get back onto his feet. He walked up behind Gabriella who was still talking to Chad. "You'll pay for th-" He started to whisper I her ear but was stopped.

Once she felt his breath on the back of her neck she brought her fist backwards with out turning around and it collided with his jaw painfully. Chad's eyes widened once again as Gabriella just grinned.

Chad got up from the tile floor and walked over to Kelsi and Taylor. "Whoa." Was all he could say.

Gabriella turned her body around and looked in Troy's eyes. Big mistake. His eyes were such a mesmerizing yet emotionless blue that she lost her train of thought for a second. She quickly regained it.

"Stay away from my brother if you ever want to have kids asshole." She hissed. She spun back around to walk over to her friends when she stopped. A rough hand had just slapped her ass and a chuckle and smirk came for the boy behind her.

She sent him daggers when she turned to him. He was now on him feet… well, f right then he was. "Say goodbye to carrying on your family name." She muttered before trying to kick him in the balls.

This time he grabbed her foot just in time. "I would only carry my name on with you baby." He tried to seduce.

"Oh really?" She raised an eyebrow. Getting closer to him she brought her mouth to his ear. "You couldn't handle me." She whispered sexily. He dropped her foot and went to wrap his arm around her waist.

Gabriella slipped back and stalked to her open-mouthed friends. She shot him the middle finger behind her back as she walked to the lunchroom with Kelsi, Taylor, and Chad.

After a few feet Kelsi started laughing. "You are good girl! I bet he is still sitting there drooling!"

"What did you whisper in his ear that made him freeze up?" Taylor laughed.

"That he couldn't handle all this!" Gabriella laughed along and moved her hands down her sides for dramatic effect and to signal to herself.

Chad shot his sister a questioning look and raised an eyebrow. "Don't worry Chad! Even though he could not handle this bitch!" Gabriella giggled as Chad chuckled.

"Did I dream all of that or did my little sister just whoop Troy Bolton's ass?" Chad joked.

"I sure did open up a can of Chinese whoop ass huh?" Gabriella laughed along with all

the others as they walked to the East High cafeteria.

Troy licked his lips wantingly. Chad was his rival and now just by messing around with Gabriella and using his charming ways he could piss both of them off. This isn't over yet. Troy thought.
