A/N: I'm trying to include all of the characters in each chapter, but I'm worried some parts might be completely pointless, so I delete that part. I try and make the storyline go one step forward with each chapter, but you guys wouldn't mind a little fluff, right? Just wondering in case there is a mega pointless part or chapter coming up soon, lol.

Chapter Five: Betrayal

The next morning, Cristina was afraid to walk into her first hour class, knowing that Owen would be inside, and knowing that he must feel humiliated. She knew she would have been humiliated. Watching other students pass her as she stood in the hall, she noticed Owen sitting in the back, alone, with his head down. "Hi, Cristina," she heard a female voice from behind her.

Cristina watched the figure pass and it was none other than Teddy, "Aren't you going inside?" She asked with a concerned look on her face.

The brunette was tempted to turn and run in the other direction, but she couldn't run away from her fears or her worries. She needed to face them head on, "Yeah," Cristina answered with a nod of her head.

She caught Owen's eye as she entered the class, but instead of taking the seat she had the day before, she sat near the front this time. Her eyes stayed connected with his only until she noticed the look of confusion on his face when Cristina didn't join him in the back of the class. She didn't want to have that awkward conversation, not now anyway.

Later that day, Meredith entered her fourth hour Creative Writing class and took her seat next to Derek at the far left table, "Hey you," she smiled at him, "How's your pinky?"

Derek lifted his hand to show Meredith the damage her doorway caused.

"Oh my God," she winced, looking at the swollen finger that was still a dark purple, "Is it broken?"

Derek sighed, shrugging his shoulders, "I'm not sure. It hurts like a son of a bitch, though. And I can't move it," he told her.

"I'm sorry," Meredith couldn't help but to giggle, thinking back on the trouble he had getting out of her house last night, "But I have to admit, it was pretty funny when it happened."

Derek shook his head, her giggles forcing him to smile, "Well, I'm glad you're able to laugh at my pain."

Meredith looked at his finger one last night, wincing at the sight again. "It really does look bad though, maybe you should have it x-rayed."

"I think maybe you're right."

"Oh, damn," Meredith sighed, thinking about her next hour class, "Lexie is in my next hour, I almost forgot."

"Well, what are you gonna say to her?"

"Nothing," Meredith said, as if that answer was obvious.

"Nothing?" Derek paused with a confused expression on his face, "Mer, you can't just say nothing to her, after all, you are her sister."

Just then, Meredith looked daggers in his direction, "Lexie is not my sister," she paused, looking down at the surface of the table, "She's just a girl who stole my father, and who stole the life I should have now. My father should still be with my mother, but I honestly can't really blame him for leaving because my mother is always at the hospital. But you know," Meredith sighed, realizing she was rambling, "he could have at least taken me with him."

Derek looked at her sympathetically and placed a kiss on her temple since he was at a loss for words that could possibly make her feel better.

"I just need to take my mind off of a lot of things," Meredith sighed.

Derek smiled, "I have an idea. Let's go see a movie this weekend."

"A movie?" Meredith grinned, cocking an eyebrow in his direction.

"Yes, a movie. We haven't gone out on an actually date in…" he looked up, trying to count how many weeks had passed since the last time they went out in public together, just the two of them, "I can't even remember. It will be fun."

Meredith nodded her head, "Fine. But I'm picking the movie."

Derek winced for a moment, pondering that, "Fine."

Once fourth hour ended, Callie found Addison in the library checking her email on one of the computers.

"Hey," Callie smiled at her upon entering the room, "Have you seen the Government textbooks? They are thicker than two dictionaries put together."

"I know," Addison said, signing out of the computer, "I actually came in here to check out mine but Ms. Peterson isn't here."

"Oh, well, I wish I known that before I walked all the way down here," Callie frowned. Her chocolate brown eyes scanned around the room carefully, making sure there was no one there before saying what was on her mind, "I still can't believe what you told me about Izzie."

"What I can't believe is that she's actually going to get an abortion," Addison shook her head at the thought.

"I don't know about you, but I think she should tell Alex. I mean, he is the father, he has a right to know," she said, making sure she kept her voice quiet.

Addison shrugged her shoulders, "I don't know. We both know Alex… he's Alex. I'm not saying he's a bad guy, and I'm not saying I'm supporting his…" she paused, thinking of the right word to say, "attitude. But, do you really think he's going to do anything about it?"

Callie was silent, knowing that Addison was probably right, "Still," she paused, "He should know."

"Like you said… not a soul," Addison pointed a finger at her with a stern look on her face.

"Addie, relax. I'm not going to tell anyone."

"Good."

As they both began to leave, George walked from one of the aisles of books in the library with a shocked, and hurt expression on his face.

Callie sat with Arizona same as the day before in their art class during fifth hour. All of the students were talking amongst themselves, so there was a consistent murmur in the air. Arizona showed off her dimples in Callie's direction, and the brunette could feel her blue eyes burning into her like a laser. Callie finally looked up from the paper on the desk and smiled when she realized that Arizona was just staring at her, "What? What are you looking at me like that for?"

"It's later," she answered simply.

Callie furrowed her brows curiously, "It's later?"

"Yeah," she replied with a nod, "It's later. So tell me what Mark was going to say yesterday at lunch before you kicked him."

Callie felt her cheeks heat up, and her stomach felt like a huge knot but the smile didn't fade away, "Oh, right… that," she paused, sinking her teeth into her lower lip as she gathered the words in her mind that seemed to be hiding, "Well, I'm pretty sure that Mark was gonna tell you that… I'm into girls too."

Arizona's smile grew wider, even though she already figured that's what it was going to be. She just needed to be one hundred percent sure, "Oh," she smirked, "I see."

"Yeah," Callie replied, looking down at her hands. She began to scrape some of the black finger nail polish from her thumb nail, it was a nervous habit of hers.

"Now that I know it's safe to ask you this question…" Arizona paused, letting her blue eyes examine Callie's features. But she never got to ask the question. She was interrupted by an anxious Cristina who hastily sat at their table across from the brunette.

"Callie," she started, and the blonde's smile faded quickly, "If you told someone you loved them and they didn't say it back, how exactly would you feel?"

Callie narrowed her eyes, slightly annoyed that Cristina interrupted what Arizona was going to say, "Um," she had to process Cristina's question, "I'd feel exposed, vulnerable, and humiliated," she answered honestly.

"Damn it," Cristina grumbled under her breath, "I had a feeling you were going to say something like that."

"Why?" Callie asked before it dawned on her that something must have happened with Owen, "Did Owen tell you he loved you?"

Cristina sighed deeply, "Yes," she said, an annoyed tone filled her voice.

"And you didn't say it back, did you?" Arizona chimed in, shaking her head a few times as she spoke.

"No shit, Sherlock," Cristina scorned, laying her face down onto the surface of the table.

Arizona's face twisted as if she was about to say something back to Cristina, but Callie picked up on the look that took over the blonde's features and she shook her head quickly as if to say just drop it.

"God, I don't know what to do now," Cristina complained, lifting her head back up, "I want to say it back, but I know I only want to say it back to keep him happy. I won't be saying it because that's how I really feel."

"Well, how about you tell Owen that. Tell him you want to be able to say it when you really mean it. He'll want to hear you say it when you can actually mean it," a smile formed on Callie's face.

Cristina nodded her head, thinking about what Callie said, "Yeah, that's what I'm gonna tell him," she paused, letting out a quick breath, "Thanks."

"Don't mention it," Callie told her.

Cristina smiled with a nod of her head, standing from the table and returning back to the table where she was sitting before. Callie's attention turned back to the dimple-faced blonde soon afterward, "Alright… now… what were you gonna ask?"

Arizona smiled, "I was going to ask if you were available Saturday night. Maybe you want to see a movie with me or something?"

Callie nodded her head, a smile forming on her lips, "I'd really like that. A movie… or something," she paused, letting out a quick breath, "sounds good to me."

"Yay," Arizona said softly, her teeth sinking into her lower lip.

When the bell for lunch rang, all of the students piled into the cafeteria. Except for George, of course, who stood in a vacant corridor waiting for his so called "best friend" to pass by in the hall. He stood there for nearly five minutes, until the hallways cleared, wondering if Izzie was even going to show up. While chewing on his nail in frustration, George peeked his head around the corner and noticed izzie finally making her way inside the school building from gym class.

He stood there, fuming in the corridor, and biting his thumb nail until it was sore. He couldn't believe what he had just learned, and he couldn't believe he wasn't the first to know. As Izzie finally passed the corridor, George reached out and yanked her in by her upper arm, "Izzie, we need to talk," he scolded her.

"George, what the hell," her face twisted, not expecting to be yanked into the corridor.

"Are you sure there's nothing you want to talk to me about?" George had the most dead serious expression on his face, and Izzie was sure she had never seen that look coming from him before.

She hesitated with her words, "Yeah, I'm sure. What's going on with you, George?"

George shook his head. His best friend just lied to his face, "What's wrong with me? You want to know what's wrong? I'll tell you what's wrong. What's wrong is that you told Callie and Addison that you were pregnant!"

Izzie's eyes widened, and she quickly glanced around in the halls to make sure everything was clear, "Would you keep your voice down please?" She said in a low, but stern voice.

"So it is true…" George sighed with the same frown on his face, "Actually, that's not why I'm upset. I'm upset because you told Callie and Addison before you told me. And I'm supposed to be your best friend."

"Wait," Izzie winced, "Callie knows?" Once the realization set in, a frown formed on her face, "I'm gonna kick Addison's ass."

"Why didn't you tell me? Why'd you tell Addison of all people?"

Izzie let out an exasperated sigh and rubbed a hand over her face, trying to wipe away the frustration that was building up inside of her, "I didn't tell Addison anything. I didn't want anyone to know."

George stood there silently, and he released a sigh that calmed him down a little more, "You're getting an abortion?"

Izzie released a sigh as well, which only made her feel like crying. And George could see the tears building up in her eyes.

"Yeah," she whimpered as George pulled her into a hug. Izzie buried her face into his neck, his skin muffled the her low sobs as he rubbed her back, trying his best to comfort her.

"You'll be okay," he told her softly.

What Izzie and George didn't know was that Alex got held up in wrestling practice. He was walking down the hall when he stopped hearing the sound of George's voice, "You're getting an abortion?" It stopped him dead in his tracks. It was as if his heart stopped beating for a split second when he heard Izzie's voice after that. Not wanting to be seen, he forced his legs to make a U turn and head in the other direction back to the locker rooms. He just kept telling himself that it wasn't his baby in his mind.

Lexie had detention for the rest of the day, since she was late for her fifth hour class. Of course, she was purposely late. Even though she wanted to actually meet her sister and get to know her, she wanted to give Meredith a little space first. And the only way she could do that without being tempted would be to stay away from her completely for right now.

After lunch, Lexie made her way back to the detention room and sat down in the back. It wasn't too long before a new addition to the room entered. Mark Sloan, being the horndog he's always been, took a seat next to the only girl in the room.

Lexie just glanced in his direction before looking down at her hands that were in her lap.

"You don't look like the type to get detention," he smiled her way, and her eyes soon met with his.

"I was late," she replied simply.

Mark nodded, he figured that was what she was in for, "I'm Mark, by the way."

A smile crept onto her face and she cocked an eyebrow, wondering why someone as gorgeous as this guy was actually speaking to her, "Lexie Grey," she said back.

Mark then lifted his eyebrows, "Lexie Grey. Weird, I know a Meredith Grey," he chuckled to himself a little.

"You do?" She asked with a little more pep in her tone.

"Yeah," he nodded.

Lexie looked down at her hands again and released a sigh, "I was actually late on purpose. Because I wanted to give Meredith a little space. After all, she just found out I was her half sister yesterday."

"You're Meredith's sister?" Mark asked, sounding surprised.

She simply nodded in his direction.

"Never thought detention would be this interesting."

I wanted to try and give Mark a little bit of a storyline in this. Hope you liked this chapter! Thanks to all who are reading and reviewing, reading the reviews really makes my day!
