Issues with the Ex-boyfriend

She walked into the elevator. She actually walked into the elevator. With Burke inside. She felt a pang of guilt. Derek coughed. Cristina looked at him, and Derek jerked his head towards Burke. She sighed. "Burke, I…I have something to tell you. I'm sorry for everything, and I just want you to know…"

"Save it, Dr. Yang. We have more important matters to deal with."

She was silent after that. Derek and Cristina worked on Burke's hand. Cristina said, "I'll be right back."
She ran to the bathroom and returned a few seconds later. "Ok. I'm back."

"You feeling okay Dr. Yang?" Derek asked.

"Yes. No. I don't know. Am I okay?"

"You don't look so good. Maybe you'd better call in sick."

"Hmph. Yeah, right. When would I ever do that?"

"Dr. Yang, we are going to finish this surgery and then you are going home. I'll make sure of it."

"Oh, please. You only care because I am Meredith's friend."

"No, I care because you are also my friend. I'll give you a ride." He finished with Burke's hand and turned to Cristina. Cristina turned and ran to the bathroom again. She came back out, saying, "I'll be fine. I just had food that didn't sit well."

They rolled Burke into the hospital room and woke him up. Burke said, "How's my hand Dr. Shepherd?"

"Your hand will be fine. However, you are not fine."

"What makes you say that?"

"You ignored Cristina when she was trying to apologize. If you would just hear her out, maybe you'd understand."

"Understand what? That she walked away, and she told the chief? I understand that plenty."

"No. You don't understand. She knew she did wrong. She wasn't being selfish. She was trying to look out for you, not herself. She cares about you. She would give her life for you. I'm sure she would apologize a…"

"20 million times. I will apologize 20 million times if I have to. You can forgive me if you want because you want to, not because I want you to and I will understand."

Burke turned his head to see Cristina standing in the doorway with tears in her eyes. "Cristina…I should be the one who's sorry. You were right to go to the chief. I just didn't see that. I'm sorry. I forgive you and I hope you forgive me." Cristina ran up to him and kissed him. Derek turned towards the door, smiling inwardly. Meredith showed up and they were watching through the window, holding hands. Meredith turned to tell Derek how much she loved him when Cristina broke away from Burke and ran to the bathroom. Meredith ran in. "Cristina, are you okay?"

"I'm fine. I just had some breakfast that didn't sit well."

"You didn't have breakfast, Cristina. I was with you all morning. Are you truly okay?"

Before Cristina could answer, she vomited again. Then she collapsed. "Cristina!" Burke yelled, concerned.

"I'll be fine. Just. some issues." Meredith and Derek each grabbed an arm and hauled Cristina to her feet. As they were walking out of Burke's room, Meredith said, "Don't worry, Dr. Burke. Cristina's going to be just fine. She's going to see Dr. Montgomery or Dr. Bailey." After they left the room, Burke leaned his head back on his pillow. he wondered about Cristina. He definitely wondered.
