DISCLAIMER: I don't own Star Trek.

This is potentially the beginning to a long McCoy/Chapel story. Codeine is part 1 in a 4 part story. Each part with be related to each other. Some parts will be short while others will be much longer. Hopefully, I get to finish what I have planned to do. So far I have written bits and pieces for each story in this series.

I am not a writer by any means, just a graphic designer who is relieving stress. I have no beta, forgive my mistakes.

Rated T for language.

Enjoy!

McCoy was standing in his dorm room looking at a knocked out Jim. He shook his head and mumbled, "Who the hell gets wasted the night before classes start and then sleeps with a random woman and waits to find out the next morning that she has an angry husband. I should of left him on the curb."

He sighed and gave Kirk one of his precious hyposprays he borrowed from the Academy clinic. A beeping sound came from McCoy's PADD and his eyes darted to the alert. His Trill Neurology class was starting right now, he couldn't remember the last time he was late to a class. It had to be in high school. McCoy groaned and looked at Jim with harsh eyes, "Dammit, Jim!"

He wasn't even dressed in his cadet uniform yet. He didn't even get a chance to shave. As Bones rushed to get dressed he eyes his razor and the glass of bourbon on the desk. He grabbed the glass instead, he was going to need it. Quickly, he fumbled around some more and ran out the door with his PADDs.

He made it to the auditorium and walked in. His instructor gave him a furrowed look, but even with her annoyance he noticed her blue eyes immediately. She looked like she wanted to reprimand him but thankfully she didn't and returned to her lecture. He swiftly scanned the room and couldn't find a single seat except for one in the very front. He sighed and sat there. McCoy looked at the woman again. Her slim and fit figure was attractive. He noticed some wisp of hair falling into her face and for some reason he had the strong desire to move the behind her ear. He scanned her again and his eyes rested on the pleasing form of her legs. A voice rising in volume brought his attention back to the lecture.

"Cadet? What's your name" McCoy looked up at the person speaking, it was the instructor. He sure as hell hoped she didn't notice where he was looking.

"Uh...Cadet McCoy, Leonard McCoy"

"I was going over the syllabus on file 23.45.7 on the server. I suggest you open it." She gave him a stern look, making her eyes look like ice, "I was going over the late policy, it says that if your going to be late you might as well not show up to class. The same goes for assignments. I have no tolerance for late work. Cadet McCoy, I will let you go this time, but in the future don't be late. "

McCoy felt anger flare up in his chest. He was a doctor, not some reckless cadet like Jim! He took a deep breath to calm himself, it wasn't worth arguing with an instructor to get a citation."Yes, understood."

She nodded, "Good."

McCoy looked for the syllabus on his PADD, he looked at the instructor's name on the top of the document. Lieutenant Christine Chapel. There was a small paragraph with her background. He read through it she had an extensive bio-research background and few degrees in various scientific fields. He looked at her credentials. She was a nurse. If there was anything he learned from all his years as a doctor it was to never piss off a nurse, and he had done just that.

The lecture became very engaging as Lieutenant Chapel talked about the neurotransmitters in the Trill brain. Chapel lectured in detail about the isoboramine transmitter of symbiont. It was probably the most enthralling lecture he had watched in a very long time. After the lecture, all the cadets got up to leave and he decided to approach Lieutenant Chapel about some interesting points. She gave him a cold look as he got closer to her. He definitely made a bad first impression.

"Lieutenant Chapel, don't you find it bizarre that even when a host and symbiont are separated both seem to die regardless of the health of both, but that a symbiont can die and yet the host can live on."

Chapel had a surprised look on her face.

"Yes, Cadet. I'm impressed. I didn't think you would be the type of person to have some knowledge on the subject. What are you specializing in?"

"I'm actually a doctor. I've had an interest in Trill neurology for quite some time. I've read some medical journals on the subject."

"Ah, I thought you looked too old to be a cadet. Where did you go to medical school?"

"Mississippi Medical."

Chapel's eyes widened slightly. "What was your full name again, Cadet?"

"Leonard McCoy."

"Wait a second. I was wondering why your name was so familiar. You had brilliant research on pheromones in Orions and their affects on telepathic beings. I was blown away with some of the theories that you came up with. After that I went though and read some of your other papers," she paused, blushing a bit about her confession and then wondering why he was standing in her classroom, " wait, why are you in Starfleet?"

McCoy sighed, he felt like everyone asked him that. It took him a moment to reply but he saw that Chapel's eyes seemed trusting, "I decided to join Starfleet because I had nothing left to lose ."

Lieutenant Chapel nodded her head. Curiosity and a sense of sympathy flashed through her eyes and she concluded not to pry, "Well, Cadet McCoy, I look forward to what you have to say about isoboramine transmitters in the next assignment. I have another class to lecture. Good day. "

She gave him a warm smile that lit up her eyes. For a moment, McCoy's heart rate accelerate. He watched her exit the room with a small smile on his lips. He hadn't felt something like that in a while. Hopefully, it was just because she had a pretty face. McCoy heard an alert and looked at his PADD and frowned. "Damn, not again."

He was already late to his next lecture. He gathered his things and started to run.

This was an interesting start to the semester.
