"Dr. Bailey?"

"Yes, Dr. Karev," Bailey replied as she continued reading the chart in front of her.

"I was hoping that I could work the Code Team for an hour or two."

Bailey snapped the chart shut, "And why, Karev, would you think that I would assign you to the Code Team? Did I, or did I not, assign you to labs?"

"Yes, Dr. Bailey, you did, but"

"But nothing, Dr. Karev," Bailey interrupted. "I assigned you the labs for a reason, and I assigned the Code Team to Stevens for a reason. Do you have a problem with that?"

"No, but," Alex began again.

"Karev, I'm not going to tell you again," Bailey began threatening, this time to be cut off by Alex.

"Dr. Bailey. If you do not switch Izzie off the Code Team, she is going to lose it. Do you want to be the resident responsible for the head of the Code Team having an emotional breakdown in the middle of a Code Blue?"

At her silence, he said, "I didn't think so. I'll find Izzie and let her know we're switching."

As he walked away, Dr. Bailey just shook her head. She had to get stuck with the needy interns.

"Ow! What the hell was that?" Mark yelled from the floor, temporarily blinded by the sucker punch that had just hit the side of his face. As he looked up, though, his question was answered. "Derek. I didn't know you were in New York. Did you fly all the way back here just to see me? You really didn't have to go to all that trouble. You could have just sent a card."

Derek had already turned and walked away. He hadn't even really planned on hitting Mark—it just kind of happened—but he sure as hell didn't want to talk to Mark.

"Addison," she heard him call her as he entered the room. Why hadn't she locked the door? "Addison." He came closer.

"Leave me alone, Mark."

"Your husband just sucker-punched me."

"Good," she replied, not really listening. "Wait, what?" She turned to look at him for the first time in their conversation.

"Laid me out on the floor without so much as a hello, or a good-bye for that matter."

"Derek hit you."

"The swelling and blood would indicate that—yes."

"He hit you." The disbelief was still evident in her voice.

"Yes, Addie, he hit me." If he had been hoping for her to react with some kind of concern for any pain he might be feeling, he was sorely disappointed. This stunned incredulity was not the reaction he had expected.

"He hit you," she stated to herself as she walked past him and out of the room.

Mark just sighed. He should have expected this.

"Izzie," Alex shook her out of her trance. "Izzie."

"Go away Evil Spawn."

"Bailey's switching us," he stated simply, handing her a stack of paperwork. "You're on labs."

She looked toward him, confusion evident on her features. "But, but, she said that I had to run the Code Team."

"She did say that, and you did run the Code Team, and now, she wants me to run the Code Team. So, go deliver those labs before she lands both of our asses in a sling."

Still slightly stunned, Izzie accepted the stack of files from Alex and moved toward the door. "Thank you."

With a slight smile, Alex just shooed her out the door, 'Go."

She smiled, nodded, and went to deliver the labs.

Derek was seething. Now was probably not the best time to return to his and Addison's brownstone in Midtown, but he wanted to grab his stuff and be out of there before her shift ended at the hospital. He couldn't deal with seeing her. From the nurses' conversation, it sounded as if Mark and Addison were together, at least until the nurse. How long had they been together? Was the night he found them really the first time, or had it been going on for years right under his nose?

He tried to drive all of these thoughts from his mind; they were impeding the packing process, and he need to pack quickly to get out of that house. Why couldn't he find his damn tackle box? It wasn't like Addison would have used it in his absence. He slammed the cabinet door closed in frustration, yelping when he didn't move his other hand out of the way quickly enough, and swearing again when he heard the front door open.

"Derek?" she called.

Crap. She must have seen his coat in the hall closet. Old habits die hard. He heard her heels coming down the stairs. "Derek?"

"I'm just looking for my tackle box," he stated, his voice devoid of any emotion.

"Okay," she said, uncertainty palpable in her voice. "I'm going to make some tea. Do you want some?"

"Don't, Addie," he said sharply. "Just don't."

"Don't what, Derek? I'm just asking if you want tea," she replied defensively.

"Don't act like everything is normal!" He yelled at her. "Don't stand there and act like this is any other day, like we are still living here, like you didn't stay with Mark after I left!" He hadn't meant to bring it up; somehow the words just flew out of his mouth.

"Exactly, Derek!" she yelled right back. "After you left. You left me, Derek. Hell, you didn't even really leave me. Saying that you left me implies that I was actually present when you did the leaving. No, you cowardly bastard, you just packed and moved away while I was at the hospital without telling me! I had to come home, find all of your stuff gone, without so much as a note or a forwarding address for your mail! No, Derek, you do not get to yell at me for what I did after you abandoned me!"

"You slept with my best friend!" he fired back as he advanced on her. "In our home, in our bed!"

"I am sorry, Derek," she screamed, despite the fact that he was only a few feet away. "It was a mistake, a huge, terrible, horrible mistake, and I would do anything I could to take it back, but I can't."

"No," he leveled. "You can't." He started to brush by her up the stairs.

"Great, Derek," she shot at him. "Take the easy way out and leave again."

"Easy!" he yelled again. "Easy! What about any of this situation has been easy? I uprooted my entire life and moved to Seattle because I couldn't stand to occupy the same plain of existence as my cheating wife and my Brutus of a best friend!" He moved closer to her, invading her personal space, "You destroyed my life, Addison. You were my life, and you destroyed it, so don't talk to me about easy."

"You are so full of it, Derek."

"What?" His voice was incredulous.

"I had ceased to be your life or even a minor aspect of your life for years, so don't give me that bullshit about me destroying your life."
"Bullshit! How is that bullshit! We were married, Addie! Married! By definition, you were a major part of my life!"

"We had the certificate, Derek, but we were not married. Married people see each other! Married people talk to each other! Married people actually care about each other! We weren't doing any of those things!"

Derek suddenly stopped yelling. "Married people also have sex with each other. Just each other."

Addison simply shook her head as he walked away, "Derek . . . ."

"Not now, Addie."

She wished that phrase wasn't so familiar.
