"You're joking."

Emily ignored the stares from her friends as she cleaned the blood from her hands. Earlier that day, the intern had been assigned a little boy whose leg had been cut, and after she had stitched him up they had found an infection, and it had had to be amputated from his shin down.

"He can't be married," Izzie breathed. "Are they divorced?"

Rushing over to the small group of girls, Meredith held up her phone. "I found her!" Showing the phone to the other inter, the blond huffed. "Addison Shepherd: OB/GYN and Neonatal specialist."

Cristina frowned. "World renowned?" she read off the screen. "That's not true. I haven't heard of her."

Emily felt herself grow sad at the thought of the man she'd slept with having a relationship with the redhead that had crashed their date night. The thought of them even holding hands had her stomach rolling.

"Em?"

The brunette turned her head, seeing Izzie and Meredith giving her concerning looks. "I'm fine," she shrugged. "It wasn't a date, remember? Just a dinner between friends."

"But you slept together," the former model sighed.

Emily gave a slow nod of the head.

Meredith stepped closer to the brunette and moved a stray curl from her face. "He slept with you and didn't tell you he was married."

The ambassador's daughter breathed out a laugh, grabbing a paper towel to dry her hands. "I got that much from the story." Shrugging her shoulders, she threw the paper towel into the trash. "Guys, I really don't want to talk about it."

Cristina nodded in agreement. "Emily has spoken. Let's get back to work."

The ivory skinned woman followed her friend out of the bathroom and out onto the surgical floor. She hadn't spoken to Derek after what had happened and she surely didn't want to talk about it with anyone else.

"You didn't sleep together again, right?"

Emily made a face.

Cristina shrugged. "Because then I'd get why you were upset. But if it was a one night stand and neither of you want it again, it shouldn't be a problem."

The ambassador's daughter ran a hand down her face. "Yeah."

"We can talk about it later."

Emily stopped her stride as she reached the nurse's desk. "With tequila?" she asked hopefully, smiling sadly when Cristina turned back to face her.

The Korean woman was quick to nod her head before walking away.

"Prentiss."

Emily turned to see Dr. Burke walking up to the nurse's station. "How are you?" she smiled, taking the newest file from the nurse closest to her. "I heard about your emergency septal myectomy on Saturday. How did everything go?"

The doctor looked impressed. "Very smoothly."

"That's amazing," Emily grinned up to the older man. "Was Cristina able to watch?"

Burke tried his best to hide his surprise at the question, feeling the famous doctor's daughter's eyes narrow on him as he hesitated to answer the question. "Cristina?" He made it a point to act as casually as he could, taking the file the nurse behind the desk was handing to him.

"Yang," the ambassador's daughter clarified. "Intern Yang?"

"Oh, Cristina Yang," Burke nodded. "She's extremely talented, yes? She wasn't able to stand in on my procedure yesterday but maybe next week."

Emily smiled to the older man as he walked away, hiding the smirk that wanted to appear.

"Emily?"

The familiar voice had Emily's body standing straight and turning away from the desk. "Thank you, Sheila." She walked toward the elevators and pressed the lower level button, doing her best to ignore the man calling her name.

Derek raced around a group of nurses to catch up to the younger woman. "Emily," he breathed, standing in front of her.

"Derek," she smiled politely, her head in the file she held, "how are you?"

The neurosurgeon frowned. "You've been ignoring me."

Hearing the ding of the elevator the intern's head popped up, watching as the doctors in the elevator almost pushed her one night stand out of the way to get by with their patient on the gurney. "I'm sorry you feel that way," the intern shrugged, walking into the elevator. "I haven't meant to."

Derek sighed, stepping into the elevator with the younger woman. "Emily, I'm sorry."

"For what?"

After the elevator doors closed and he could see the brunette before him wouldn't look up from her new file, Derek stepped to the right and pulled the alarm button.

Emily's hand shot out, steadying herself and gripping the bar that ran along the elevator walls. "What?"

"You did it to me once," he shrugged. "It's only fair."

Frowning, the intern closed the file in her hands and held it to her chest. "I'm sorry if you think I've been ignoring you," she tried, "but I haven't done it on purpose."

Derek slowly shook his head, stepping toward the beautiful woman before him. "Emily, I'm so sorry."

"For what?"

The neurosurgeon moved his hands through the air as if to find the right words. "Addison."

Emily met the eyes of the older man and bit her lip. He looked upset, but she couldn't put something so serious behind them just like that. "I was trying to explain to my friends that it wasn't a big deal because we were just trying to be friends."

Derek's eyes shot open. She had told her friends?

"But we slept together," she said quietly. "I slept with a married man."

The surgeon stopped his movement toward the intern. He could see her dark eyes grow sad as she continued to look at him. Had he really hurt her that badly?

"I get that you don't really understand."

Derek was taken back. "What do you mean?"

Emily let out a breath. "Have you slept with a married woman?" she asked. She laughed humorlessly, watching as the older man looked down to the ground. "If it was a one night stand and neither of us had to see each other again, it really wouldn't have mattered. But we work together." The looked Derek was giving her made her heart clench. "And then you tried to be my friend, and never once did you try and tell me about her."

"I left her. I don't want to be with her anymore," he tried to make her understand.

"But you're not divorced. You're still married."

Stepping to the side, the neurosurgeon let the ambassador's daughter press the alarm button to start the elevator back up. "I am sorry."

Emily passed him by as she stepped out onto the second floor. "Me too," the intern almost whispered, leaving the older man by himself in the elevator.
