Meredith walked into the hospital the next day. Her head was throbbing, so bad it was hard for her see straight. She got off the elevator and walked into the locker room.

"Hey." She said and they all responded in the same manner. She cringed as Alex slammed his locker. "Damn it, Alex." She said rubbing her temples.

"Rough night, Grey?" He asked with a smug smirk.

"An alcohol-filled night." She said lying back on the bench. "Work and hangovers don't mix."

"And you haven't even made it out of the locker room yet." Christina stated. Meredith looked up and glared at her.

"Come on. We have to go meet our interns." Izzie called from the door.

"Another day of babysitting." Christina mumbled as she walked by Izzie and out the door. Everyone else except Meredith left as well. Meredith continued to lie on the bench with her eyes closed. She soon realized that it was time to get going so she got up, quickly changed, and walked out.

"Alright, assignments." She sighed and looked down at the clipboard rubbing her temples. She noticed a shadow on her papers, so she glanced back. "Is there something I can do for you Dr. Sloan?"

"Two things, actually." He spoke quietly obviously suffering from a hangover as well. "I need to talk to you and I need an intern."

"Can't get your own coffee today?" She asked not really looking at him.

"I'm feeling particularly lazy. Besides, I have dry-cleaning to be picked up."

She rolled her eyes glancing up from the clipboard. "Grey, go."

"Actually, I was wondering if I could work with Dr. Shepherd." She smiled brightly. "I have an interest in Nuero."

"I'm sure you do." She mumbled writing something on the chart again. "Are you saying you can learn nothing from Dr. Sloan? That he can not teach you anything?"

Lexi's eyes darted from Mark, who was standing there with his arms behind his back with a smug look, and Meredith, who was glaring at her as she used the arm she had propped up on the nurses' station as an armrest.

"N… No." She stammered. "I just have an interest in…"

"I gave out the assignment. You do it. I don't care if you have an interest in Ortho or OB or Cardio or Nuero. If I say Plastics you better believe that you'll be with Dr. Sloan today even if it means being his little secretary." She hissed. Mark let out a chuckle about the secretary comment. "As for you two, Rogers-pit. Moore-Shepherd."

The two left as Meredith started walking down the hall. Mark followed causing Lexi to follow.

"Got to hate hangovers." Mark commented as Meredith glared at him.

"Don't pretend like the all-masterful Mark Sloan doesn't have one. I know symptoms of hangovers."

He chuckled. "You're such a doctor."

She rolled her eyes. "So what do you need, Dr. Sloan?"

"Just checking up on you. You know the two of us have to stick together."

"Why is that?"

"We're the Dirty Mistresses." He sighed as his pager went off. "I'll see you around, Grey."

"You too, Sloan." Mark turned and wasn't paying attention to where he was going almost plowing over Lexi.

"What the… How long have you been following us?" He asked.

"The whole time." Lexi said shrugging. Mark looked back at Meredith and scowled.

"Let's go." He said before walking off.
