A/N: You'll notice that in previous chapters, then again in this one, and in some others I borrow lines from the show…that's all Shonda's creative goddessness, and I'm just incorporating it for effect :)

The next morning Meredith and Christina had to wake up early for their organic chemistry synthesis lab. "This whole waking up at 7am for an 8am class after a night of drinking and going to bars isn't going to fly," Meredith moaned as she rolled her tired body out of bed.

"No kidding," Christina said as she took an aspirin and Meredith threw on a grey long-sleeved Dartmouth t-shirt and a pair of jeans.

The pair walked out their dorm and over to the science building to go to their lab. "I really don't see why knowing how to draw diagrams of carbon compounds will help us when it comes to performing surgeries," Meredith complained as she slung her khaki canvas tote bag on their lab table.

"Carbon is the basis for all life in the universe. Of course it's important!" Christina said, excited that with each class and each lab, she was one step closer to medical school and becoming a surgeon.

Meredith rolled her eyes at Christina as the professor from yesterday's organic chemistry lecture came threw the door. "Good morning everyone. As you know I'm Dr. Miller, your professor for Chemistry 210. Usually I don't attend lab sections, but since it is the first lab of the semester I'm here to get you guys started. At this point in time I'd like to introduce you to your lab leaders, who are chemistry graduate students, and my TA's who are medical students who are here as part of our medical school's undergrad mentor program."

Meredith wasn't paying much attention and yawned as Dr. Miller gave his opening remarks. Christina sat up and suddenly seemed wide awake as class started.

"Alright, this third of the room he motioned toward the side of the room farthest from Meredith and Christina will have Tatianna and Jacob as lab leaders, and Addison Montgomery as your TA. And this third of the room he motioned toward the middle half of the room, just to the right of Meredith and Christina will have Anya and Mike as your lab leaders, and Preston Burke as your TA, and you guys he motioned to Meredith and Christina's third of the room will have Matthew and Laura as lab leaders and Derek Shepherd as your TA. I will now turn it over to the TA's and lab leaders and you guys can get started on your first lab assignment."

Dr. Miller walked out of the room as Meredith fought back another yawn, still not paying attention as Derek came over to their group to give instructions. Christina kicked Meredith under the table. "What is your problem?" Meredith snapped at Christina as she looked up and saw Derek at the front of the room dressed in a lab coat over his red button down shirt. "Oh, shit." Meredith buried her head in her hands.

Derek started calling out attendance as she ducked down behind her tote bag on the table, trying to make herself invisible. "Oh give it up," Christina said.

"What?" Meredith harshly whispered.

"I know you slept with him. I'm not that naïve. Seriously."

"What? How'd you…?"

"I forgot about our DND code and walked in while you were still passed out on your bed and he was passed out on the floor."

"And you didn't say anything to me?" She said still yelling at Christina in a whispered tone.

"What? You were passed out, I probably couldn't have waken you up anyway."

"No, I mean since then. At the bar…you could have told me at anytime that you knew."

"Oh whatever, it's not a big deal," Christina said, still looking straight ahead at Derek thinking how lucky Meredith was that she got to hook up with him. "Was he any good?"

"WHAT?" She said in a hushed yell.

"He looks like he'd be good."

"Meredith Grey?" Derek announced on the attendance sheet.

"Here," she managed to say. He looked around and then he saw her and did a double take as she cringed. He smiled for a brief moment and then continued to call names. "Well organic chemistry just got a lot more interesting" she whispered to Christina.

"I'm sorry Ms. Grey, is there something you'd like to share with the rest of the class?"

"Uh, no sir, definitely not," she said, blushing as he laughed to himself.

"Sir? You called him sir?" Christina joked.

"Bite me."

"Christina Yang?"

"Here!" Christina shouted as she shot her hand up in the air. Derek recognized her from the bar as the girl Meredith was playing pool with. He knew this would be an intriguing class.

"Okay, everyone. As Dr. Miller said, I'm Derek Shepherd, a third year medical student at Dartmouth's med school and I'll be acting as a TA for the lab section of your organic chem class. Matthew and Laura here will introduce themselves and explain a bit more about what will happen."

Derek stepped aside as Matthew and Laura introduced themselves as first year chemistry graduate students and explained that they will directly be helping the students with the experiments, while the TA will oversee everything and act as a liaison with the professor. Derek watched as Meredith tried to avoid looking at him while the lab leaders talked. Derek started to hand out lab manuals and stopped at Meredith and Christina's table, which was at the back of the room, and leaned over, inches away from Meredith's face. "So we meet again," he whispered to her and it sent chills down her back. She politely smiled and turned her lab manual to the first page and followed the instructions that the lab leaders gave.

Meredith and Christina walked out of the classroom after they had been dismissed and ran to catch up to George who had also just been dismissed from class. Derek walked out of the chemistry laboratory, ran over to Meredith, and grabbed her arm. "Meredith can I speak with you for a second?" Meredith stopped momentarily and Christina looked over her shoulder at Meredith, laughed, and continued walking.

"Derek I was just—"

He didn't let her finish her sentence and pulled her into a stairwell. "We should talk, Meredith."

"There's nothing to talk about."

"Really?" He asked doubtfully, taking a step closer to her. "We really should go someplace and talk Meredith…"

"We should pretend it never happened. This can't exist, you get that, right?" She said, looking him square in the eyes, trying to stand her ground and not give into his piercing blue eyes. She couldn't take it anymore and walked out of the stairwell, leaving Derek looking after her and shaking his head.

GAGAGAGAGAGGAGA

Back at the dorm Christina started to grill Meredith. "So what was that about?"

"What was what?" Meredith asked, trying to avoid the inevitable conversation by looking like she's deep in concentration while doing her calculus homework.

"Seriously? Meredith, the smoldering hot TA, who you've slept with, by the way, grabs you by the arm after class and pulls you into a stairwell, and you're going to sit there and ask me 'what was what'? Seriously?"

"Fine. He wanted to talk, and I told him there's nothing to talk about and to leave it alone. Then I left."

"That's it?"

"That's it. And besides, our organic chem lab is only once a week, so I only have to see him on Tuesdays. I can avoid seeing him outside of class."

"Really? 'Cause seriously, you've been so successful with that the last few days, considering you've only gone out twice since you've been here, and both times you saw him. Uh-huh, good luck with that." Christina gave her a doubtful look, and went back to studying.
