Authors Note: This is my first fanfiction. Please tell me what you think. I obviously do not own OB or any of the characters. Please enjoy. This will be a long, multi-chapter story. I will write no matter how many reviews I get, but reviews will certainly speed up my writing! This is rated M for future chapters.

Cosima stepped into the lecture hall without a moment to spare. Her dread tapped against her back as she halted and scanned the room for an open seat. The professor had just started talking, but instead of slipping into the back row she walked along the back of the hall and down the side to sit in the corner front row seat which had been left open. Quickly taking out her pen and notebook, she dated the page and listened intently to the professor.

"Welcome to BIOB 410 Immunology also known as MICB 410," the auburn haired woman stated as she leaned back against the desk. "My name is Professor Harken. I work at the local laboratory studying diseases such as Rocky Mountain Spotted Fever and Lyme Disease. I will be teaching the lecture portion of your class. There is also a lab portion which will be taught by current graduate students. Be sure not to miss any lectures or labs. They work hand in hand, and are an important part of your learning. Now-," she paused to pick up a large stack of papers on her desk. She pushed off the desk and handed the papers to a curly haired blonde who was standing off to the side. Cosima hadn't even noticed her until she started walking to the side of the lecture hall. She carefully walked up the steps and handed a portion of the stack to the person on the end of each row. The dreadlocked woman started to lean back and slouch in her chair to peer at the tall, leggy blonde. She noted her tall, heeled boots, and skinny jeans, but she jerked back forward when the professor started talking. Leaning over her desk, she rested her elbows on the table and her head in her palms.

"- Miss Cormier is handing out a basic lecture schedule which includes a chart on grading. Read it carefully as we will not be going over much of it in class."

Cosima nodded to the girl next to her as she was handed the stack of papers. She took one for herself and set it in her notebook then put the rest to the side. The professor continued to talk and go over what the lectures would cover, so Cosima took short notes to make sure to be early to class unlike she was today.

"Pardon," said a soft voice. Cosima jerked her head to the side to see Miss Cormier reaching for the stack of leftover papers her elbow was resting on. She quickly lifted her elbow and re-adjusted her seating position. Her heart pounded in her throat as her brain processed that the woman had just spoken French. She was pretty sure her brain had just melted into mush as that one word.

"Oh. Sorry, sorry. Yeah, here," she whispered in a fluster as she made sure they got into the taller girl's hands. Their fingers brushed, and Cosima was sure she was going to become a puddle right there. She looked down just as the French woman smiled warmly at her and whispered a quick "merci". Then she walked up to the desk and set the papers down. Straightening up, she went and stood next to Professor Harken. The professor turned toward her student teacher and motioned wordlessly before continuing.

"Miss Cormier is a graduate student here and will be assisting in the lecture, and she will also be teaching the BIOB 411 Immunology Lab if that is the lab you have chosen to go along with the lecture. Go ahead and introduce yourself," the Professor said with a nod to the graduate student.

"Hello," she said with an obvious French accent. "I am Delphine Cormier, and, as Professor Harken said, I am a graduate student who currently has an internship in the immunology field. I work with Harken at the lab assisting in the study of diseases that affect the surrounding area. Feel free to call me Delphine. Miss Cormier is quite formal. I have office hours which are listed on the handout. You may stop by or make an appointment to see me ahead of time if you need help with anything. I look forward to, uh, well, helping you all expand your knowledge in this great field. I hope you enjoy immunology as much as me."

Cosima watched Delphine intently and leaned over her table. The way she moved her hands with her words had the brunette entranced. The passion behind Miss Cormier's words was not lost on Cosima, as she studied the graduate student's lips. She noted the way Delphine's lips stayed slightly parted during pauses. Thankfully, the rest of the class went smoothly with Cosima only getting lost in Delphine's mannerisms a couple of times. As the class ended, and everyone gathered there stuff to leave, she left her belongings in her chair and approached her professor.

"I'm Cosima," she said while holding her hand out. "I just wanted to introduce myself. You'll probably see me during office hours at some point, and I thought why not go ahead and say hi now."

"Well, Cosima," Professor Harken spoke while taking her hand warmly, "Thank you. I hope you enjoy my lectures."

The professor smiled curtly then turned to another student which was standing next to Cosima and started to answer his question. The brunette nodded quickly with a smile then stepped to the side and looked over at the blonde graduate student. Delphine had her hands at her waist and was arching her back as she looked around the room. She didn't notice Cosima right away, so the brunette took the time to glance over her with what she convinced herself was a purely scientific curiosity. When Delphine finally spotted Cosima, she smiled and turned her body toward the glasses wearing girl.

"Hello," she said. Her French accent was obvious, and it made Cosima's mind blank just long enough for her words not to come out right.

"Oh. Oh! Um. Hey. I'm Cosima. I thought I would introduce myself. You'll probably see me during office hours," she spoke with a slight head shake and small wave to break herself from being caught in Delphine's gaze.

"Enchanté, Cosima. I am Delphine." A warm smile met both their lips.

"Enchanté," she replied in a thick American accent. "And, uh, you- I can come see you during office hours if needed? I believe you're- you're also teaching my lab portion."

"Ah," Delphine smiled and nodded her head enthusiatically, "We will get to know each other well then, yes?"

"Uh huh. Well, I, I should be going to my next class."

"Oh yes. Don't be late."

Cosima started to turn then felt a smile tug at her cheeks, and she turned her head back to look at Delphine.

"Yeah… Kinda always late. Kinda always sorry."

The French girl laughed breathily and placed her hand on her stomach.

"You are, how do they say? Very, uh, cheeky, yes?" She placed her fingers over her mouth when she smiled, and the smaller woman couldn't help but let her lips part slightly while entranced in Delphine's subtle movements.

"I guess you could say that." Cosima said with a throaty laugh, "Well. I'm off. I will see you… later?"

"Oui!" Delphine said excitedly as she waved while Cosima walked off.

The brunette walked back to where she was sitting and gathered her belongings into her bag. Then she hurried out of the room to her next class. Delphine had watched her out of the corner of her eye as she exited the room. Once the girl left, she shook her head slowly in amusement. Cosima was certainly an intriguing woman.
