"Dr. Shepherd?" Katie's voice followed a knock from outside my office door. "Are you okay?"

"I'm…" Before I could even get the sentence out, I threw-up again.

"Should I have them take Mrs. Reynolds back to her room? Her C-section was scheduled to begin 10 minutes ago."

"No, I'm…" I paused to throw-up yet again. "I'm coming. Just give me a minute.

"Dr. Shepherd? Are you…puking?"

Apparently, my attempts to be quiet failed. Damn the thin walls. I opened the door to let Katie come inside. My intern looked shocked to see me in such a disheveled state. My hair and face were all sweaty and most of my mascara was running down my cheeks. Quickly, I closed the door behind her.

"Yes." I collapsed into a chair, exhausted.

"Are you contagious?"

"No."

"Are you sure?"

"Believe me, I'm sure. Dr. Bramwell, how would you like to do a C-section by yourself?"

"All by myself? Seriously?"

"Yes."

"I'm kinda scared."

"That's okay. I was scared my first time also. You can do it. You've helped me so many times. You know the procedure well enough to do it blindfolded."

"Thank-you! What's wrong with you? Are you…" she gasped. "No way!"

"I think so. Go make me proud with the C-section." She stared at me as I leaned over the trashcan again. "Then you can do an ultrasound."

"I'll be right back," Katie said as she disappeared from my office.

She returned seconds later holding wet towels and a cup of water then she put one of the towels on the back of my neck. The other one she used to wipe my face. Then she put a straw into the cup and handed it to me.

"Thank-you, but I don't think I can drink this." I croaked hoarsely.

"It's Sprite. Sip slowly through the straw when you've gone at least ten minutes without throwing up. Two sips. Wait a few minutes and take two more."

"Thanks, Katie."

"No problem. Now, I have a C-section to do," she said with a wide grin, "But I'll be back to check on you in about 45 minutes. Keep the towel on your neck for a while and try to rest."

I nodded miserably and watched Katie head out the door with more confidence than I had the first time I did a section on my own. I felt like a proud mother. Then I threw-up again. I leaned back into my chair, exhausted and miserable. Closing my eyes, I hoped everything was going well for Katie. Before I knew it, she was knocking on my door again.

"Dr. Shepherd?" She came into my office positively beaming. "Everything went really well!"

"Congratulations!"

"I did it all on my own! Thanks to your teaching. How are you?"

"I'm miserable, hot, and I kind of want a lime."

"A lime? You are definitely…"

"Don't say it!" I hissed, cutting her off.

"I'm sorry, but you are. Is it Mark's?"

"I don't know. There was this one time, not too long before I slept with Mark, where Derek could possibly have…"

"So, you have no idea who got you pregnant?"

"Do you know how to do a paternity test?"

"Yep."

"Okay, after the ultrasound, you might be able to do one. If I'm far enough along."

"I don't have any DNA to compare it with."

"Yes, you do. We had sex this morning."

"And you didn't take a shower?! No offense, but that's really gross!"

"I didn't shower because I was here! And I started throwing up."

"Ewww! Did you have sex in your office?"

"No, his."

"Okay let's do this ultrasound."

We went down the hallway, discussing some charts, until we found an empty room with an ultrasound machine. When we found one, we pushed a chair against the door. I settled myself on a table, feeling a bit awkward to be in the reversed role. Then Katie squirted some jelly on my stomach, and I shivered.

"That's cold! Now I understand why patients complain."

"Sorry," she maneuvered the device around my lower abdomen until a small speck popped up on the screen. "You are officially pregnant. From the looks of it, I'd say about 10 weeks."

"It could be either of them. Save Mark's DNA. We'll have to do a paternity test in two weeks."
