She rubbed her temples as she walked into the hospital.

"Hey Mer!" Izzie chirped happily as she came up beside her.

She groaned putting her hand up to keep her from talking anymore.

"Oh, a hangover. No fun." Izzie shook her head.

"You don't need to tell me that." She groaned as they walked into the hospital. The florescent lights made her head throb even more. They walked in silence to the locker room without running into anyone.

"Hey guys." George said as he walked over.

"Sh…" Meredith stopped him putting up her finger.

"She's hung over." Izzie explained.

"Ah… Want me to get you some meds, Mer?"

She shook her head. "I'm fine." She sighed before starting to change.

"So you're hung over?" Christina asked. Meredith nodded. "Did you sleep with Sloan?"

"No." She said quickly as she grabbed her coat and headed out.

Heading down the hall, she tried to ignore the thoughts of Mark popping in her head. She walked to the nurses' station where she found her interns. They didn't notice her right away and continued talking among themselves.

"Last time I checked this wasn't a social gathering." She snapped. They jumped and looked at her. "I'm not in a good mood today which means if you plan to make my day hard, I'll make you're day a living hell. Now, rounds everybody!" She turned and almost collided with someone. Stepping back, she looked up to see the person was Mark. She felt her cheeks instantly blush. "Good Morning, Dr. Sloan."

"Good Morning, Dr. Grey." He smirked at her. She didn't look at him in the eyes as she stepping out of his way and started to walk away. Unlike what she expected, he turned and walked along side of her.

"Is there something I can help you with?" She asked.

"Well, I believe this is for you." He handed her a coffee.

"Thank you."

They walked awkwardly down the hall with her interns watching intently in tow.

"Are you okay?" He asked.

She nodded not trusting herself to really say anything. Stopping in front of a room, she looked at Mark. "Rounds." She smiled lightly.

"I'll see you later?"

She shrugged before walking into the room. "Good morning, Miss. Smith." Her professional voice returned.

He smiled to himself as he watched her talk to a patient. Shaking his head, he turned and walked away. "That wasn't awkward at all." He mumbled sarcastically to himself.

------------------------------------------------------------------------------------------------------------

It was lunchtime and she had managed to avoid Mark for the most part. She wasn't sure what they were supposed to do.

"Talk about it? No that would be awkward. Forget it didn't happen? Yeah. Their friendship was too important. What if I can't? Damn it!" She thought to herself as she sat at their normal table which happened to be empty at the time. Christina was in surgery. Izzie and George were busy in the pit. And Alex was probably busy trying to get in on a surgery.

She was lost in her thoughts and too withdrawn to notice Mark come and sit across from her. When he said something, she jumped and looked up at his smirking face.

"What?" She sighed.

He chucked. "I asked if your hangover was gone."

She nodded. "How did you know I had a hangover?"

"One, I was with you when you were drinking. Two, you kept getting a pained look on your face every time there was a loud noise. Three, I heard O'Malley and Stevens talking."

She nodded not saying anything as she played with her food.

"Did he even remember? How much did he drink? Can he even remember last night?" She asked herself in her mind.

Mark just stared at her. She seemed lost in her thought. "Does she remember what happened last night? I can't just ask her. Our friendship is too important. She probably would never see me as anything more. I could never tell her."

"What are you thinking about?" He asked.

"Nothing." She sighed not looking up from her food.

"Mer…" He started.

"Yeah?"

He opened his mouth to say something, but let it close. "Never mind." He sighed.

She looked at him for a second before returning her eyes to her salad.

"Does he remember?" She thought to herself.

"She has to remember." He thought.

"He needs to remember!"
