A/N: Okay. There are a few things that you need to know before you start reading. Firstly, English isn't my first language. But it should be perfect. Also, I'm very straight. So in future M-rated chapters, I may or may not be able to deliver the 'action' all that well. We'll see. This is also my first shot at writing something on a relatively large scale. SO, please be gentle. ;)Reviews, PMs, and basically your opinions are welcome!

CHAPTER 1

"I thought you'd be late," said Arizona to her best friend, who had arrived at school well within time.

"Oh there's NO way I'm ever late. Except when I want to be," Callie smirked.

Arizona raised her eyebrows and sniggered. "And when is that? When all your lover boys decide to ask you out TOGETHER between classes in the hallway to see who you'd pick?"

"Oh really? Was I the one who got asked out by Jackson Avery in the cheesiest manner? 'I want to marry you, Arizona! And have your kids! You know how much I cried when you went to visit your grandparents?' Or waiiiit! Wasn't it Alex Karev who cried when he found out you actually accepted Jackson's cheesy proposal? He didn't talk to you for days! That must've been horrible for him! And you know I could go on…" Callie trailed off, smiling devilishly. She cringed internally when she remembered Arizona had actually dated Jackson. Something about all the guys who liked Arizona really ticked her off. However, she loved getting under Arizona's skin by reminding her of all the creepy proposals her best friend had received over the years. And wow, were there! Both she and Arizona were popular, but most people found it easier to like Arizona because she seemed a lot more approachable than Callie. Callie came across as intimidating the first time people met her.

"Hmph… Okay… And technically I did not accept Jackson's "cheesy" proposal. I just agreed to date him. And he most certainly didn't CRY when I went to visit my grandparents! And we're not together anymore. I broke up with him, and we're just friends now! And do you want me to get started on how many guys have asked you?" Arizona fiercely defended herself.

"Okay, okay… peace, bitch!" Callie said, winking at her best friend.

Arizona laughed. "Peace indeed, bitch!"

"Soooo! What are you doing after school today? I thought we could head out to that new Mexican place a few blocks away!"

"Ah… I have to help Derek with Math…" Arizona said, disappointed. She loved spending time with her best friend, who was the sweetest and funniest person she knew. They got along really well, and their fights were resolved within hours of taking place. But this was something she had been putting off for a while, so the day before she finally called Derek and agreed to help him out since their examinations were just around the corner. She was regretting it now, though.

"Blowing me off for guys already? And I thought you loved me!" Callie mocked.

"I do. It's just, I promised Derek a long time ago and just want to get it over with!"

"It's cool. I'll see you later! I should head to class now, Dr. Webber will be pissed if I show up late. See ya!" Callie cheerfully called out, although she was a little disappointed.

"Bye!"

"Well, hello there, Theodora!"

"Hello, Calliope Iphigenia Torres!"

"O-kay! I see my mistake… let's just call each other Teddy and Callie?" Callie said, sitting beside Teddy in the front row. Teddy Altman had almost all the same classes as Callie, and they were really good friends.

Teddy giggled. "Suits me, girl! So are you prepared for today's class test?"

"I read the chapter once. Wait, the test is on Bacterial Diseases, right?"

"Wow! You're not sure? Dr. Webber will eat you alive if you get anything below a perfect score!"

Callie shrugged. "Pfft! Nothing I can't handle!"

"Modesty is dead, isn't it?" Teddy laughed.

"Hah! You're funny, Teddy! Really!" Callie smirked.

Just then, Dr. Webber entered the class. "Good morning! Put away your papers and pencil. Today's test will be oral." The class groaned. Dr. Webber continued, "Shall we begin? I'll call out your names. You'll stand up in your seat, and I'll ask you questions. Answer all of them correctly, and you get full marks. Not to mention extra credit. If you're able to answer only one question or worse, none, stay back after the class. If a person is not able to answer a question, you can volunteer to answer. But you'll still be asked a new set when it's your turn. Let's begin.

"Rodney, Brett."

"Here, sir."

"Treponema pallidum causes which disease?"

"Syph… Uh… "

"Hm?"

"Erm… Syphillis!"

"Now, I can tell that you weren't sure and that you probably guessed, but because you were right, you get marks for it. Next question. Which of the following diseases is not bacterial: Tetanus, Typhoid, Gonorrhoea, or Measles?"

"Measles."

"Very well. You can sit.

"Altman, Theodora."

"Sir."

"Which bacterium causes Tetanus?"

"Clostridium tetani."

"Correct. And what is Tetanus also known as?"

"Lockjaw, sir."

"Well done. Please sit.

"Torres, Calliope!"

Callie stood up and smiled a little. "Please, just Callie, sir…"

"Well, 'just Callie', shall we begin?"

"By all means."

"Which bacterium causes Bubonic Plague?"

"Pasteurella pestis."

"Which bacterium causes Leprosy?"

"Mycobacterium leprae."

"Which bacterium causes Malaria?"

"Malaria is not bacterial, sir." Callie said, smiling. She was expecting a trick question. Dr. Webber always did this with her.

"Are you sure?"

"Cent percent."

"Very well. Please sit, Callie. Well done!"

"Thank you, Dr. Webber."

"Moving on… Simons, Samuel!"

"Yes, sir!"

"Which disease does Bordetella cause?"

"Uh… I know the answer!"

"Do you?"

"Um… Cholera!"

"That is incorrect. Now, tell me, which bacterium causes Cholera?"

"I don't know, sir."

"See me after the class, Mr Simons." Just then, the bell rang. "Very well. See all of you on Thursday. Keep revising!

"Callie! Wait a minute, please. Can you stay back after school and help Mr Simons here? I have a staff meeting to attend…"

"That's fine, Dr. Webber." Looking at Samuel with a look of pure hatred, Callie said "Be here after school," and left the room without another word.

"Hey! How's your day going?"

Hearing her best friend's bubbly voice, Callie turned around to find Arizona jogging a little to catch up with her. "Not so good. I'm stuck with Samuel. Ugh," Callie shuddered.

"Hey you know, he's not that horrible…"

"I don't like him. He's a liar and he rebounds on innocent girls who happen to be my friends. Stop defending all kinds of idiotic, no good morons just because they happen to be your friends."

Arizona was taken aback by Callie's rude reply. "I was just trying to cheer you up…"

Callie sighed. "I know. I'm sorry. I should get going… Samuel is already there… bye!"

"Um… Okay! Bye! I'll see you tomorrow!"

"You understand all of this. Why did you want my help again?" Arizona was surprised by how good Derek was at Math.

"Because I wanted to speak with you alone. You're always surrounded by people, or with Callie. My! What a guy has to do to just TALK to you," Derek said with a playful lilt to his voice.

"You could've just talked to me, you know. You're always too busy with Mark. What, are you guys gay or something?" Arizona only half teased.

Derek looked at Arizona and muttered under his breath, "I'm pretty sure I'm not gay."

Arizona saw the look on his face. She realized he was sitting much closer to her than when they started. Derek started leaning in. For a second, Arizona just observed him. She quickly snapped out of it and leaned away.

"What's the matter, Arizona?"

"I'm sorry Derek. I don't… I can't. Sorry. You should probably leave." With that, Arizona guided him to the door.

"Okaaaaay…"

"Yeah. Sorry. I have other things I'm supposed to wrap up. I'll see you later," Arizona said and closed the door.

'Ugh, great,' Arizona thought. 'Maybe Callie is still in school. We can still go to the Mexican restaurant she wanted to check out.' She texted Callie to see if she would be able to make it.

Hey. I'm free. Are you? We can still go to that Mexican place. – A

Within moments, her phone beeped with a text message.

*sigh* I'm not free yet. Samuel is such a bimbo. – C

The simple text message made Arizona giggle uncontrollably.

Well, deal with the bimbo. Text me when you're free. We'll try to make it work. ;) – A

Sure. Ciao! – C
