Bad Guys

You're welcome

"Wow" Meredith said as Derek rolled off of her.

"Yea." Derek whispered and configured himself so that he is on his side and his elbow and forearm held up his head.

Meredith turned onto her side so she is looking back at him.

"So what happened?"

"Well, I left the hospital, got home, walked into my bedroom and found Addison and Mark having sex."

They both started to laugh for a few minutes. They had both been racked with guilt because of what they were doing to Addison, and now she had done what they wouldn't.

"So what does that mean for us?" Meredith asked.

"It means I no longer have a wife."

"But you do. Did you even talk to her before you came over here?"

"No, she looked a bit busy." He scowled.

"Derek. Cheating is bad, but you cheated on her too. And you've been having an emotional affair for a while. So you don't get to have a high horse about this."

"You're right." He said as he bent to kiss her lightly. "So what does this mean for us?"

"Million dollar question."

Derek laughs quietly.

"So what's going to happen is we are going to do what we just did a couple more times-"

"I am liking this plan already." Derek said through a grin.

"Then tomorrow, you are going to go and confront your wife. Nicely. You are going to tell her about us so she doesn't feel as bad about cheating and she knows that you two are really over. Next you are going to call a lawyer and file for divorce. Then you are going to talk. Calmly. To your best friend. You are going to inform him that he is an asshole for sleeping with your wife but then you are going to forgive him. Then, you and I are going to try and find a place for you to live. In the mean time you can stay here."

"That sounds like quite a day."

"And if you do all of it, then tomorrow night, we can do what we just did a few more times."

"Well, I don't know about the middle part but beginning and end parts sound great"

"Ah Addison!" Derek said as he walked up to her the next day with a large grin on his face.

"Hey sweetie. You didn't come home last night."

"Oh I did."

"Well you weren't there when I woke up."

"Oh no. I came home, saw you and Mark fucking, then I went to go spend the night with Meredith."

The blood drained from Addison's face.

"Derek."

"So Meredith told me I had to be nice during this conversation. But I am not quite sure how to have this conversation nicely."

"What- what conversation."

"The one where I tell you that I am leaving you."

"Derek. You don't have to do this."

"No. I don't have to. I get to."

"What does that mean?"

"It means that I've been wishing that I could leave you for weeks now. And now I can without feeling guilty."

"Look. Derek. I made a mistake. This isn't the end."

"Addison. I had sex with Meredith. A few times. You might have made a mistake but I didn't. We are through. I am about to call a lawyer and I recommend that you do the same. I'll pick up my things in a few days when I find a new permanent place to live."

"God Derek. Just so you know. Our divorce isn't on me. This is you making the decision to end us."

"Addie. I know. Don't feel bad about it. I cheated too. I should have talked to you before going to Meredith's. You deserve someone who is in love with you and that just. Isn't me." He started to walk away.

"Derek?" She called after him. "Are you in love with her?"

"Yea." 

Later that day, after calling his lawyer, Derek ran into Mark.

"You are welcome." Mark said confidently to Derek.

Derek starred at him flabbergasted.

"Addison told me what happened." Mark continued.

"So you are expecting me to thank you for sleeping with my wife?"

"Yes"

"You know Mark, I decided I wasn't going to punch you. I was contemplating it for a while, but I decided against it. But now, seeing you, I am starting to rethink my decision."

"Derek, I did you a favor."

"How?"

"You're way to gentlemanly or honorable or whatever to leave Addison on your own. You needed to be pushed."

"Ahh. Thank you so much for making the decision that my marriage needed to end." Derek said sarcastically.

"I also did it for Addison."

"Oh just satisficing her in a way I never could. You're such a hero."

"No Derek. You have been treating her like some sort of duty. You don't love her, you love that intern. And you've been keeping Addison around so that you don't feel guilty, not actually caring what is was doing to her."

"Mark, you don't know as much as you think you do."

"I know that yesterday I called your wife hot and you didn't react, but when I called the intern hot you scolded me. I know that you made plans to eat with her and didn't care if I took Addie out.  You didn't care about what me and Addie did, don't pretend you do now."

Derek scoffed.

"And after you saw us. Where did you go?"

"That's none of your business."

"Fine don't tell me. Let me guess. I think my first guess is you went to the intern's house and did her. Am I right?"

"What difference does it make."

"The difference is I am still waiting for my thank you."

"Well you are going to have to wait for a while." He paused, "but..."

Mark raised an eyebrow.

"We are good."

"We are?" he asked a bit confused.

"Meredith said I had too."

Mark laughed and patted Derek on his shoulder, "You're welcome."

Derek smiled a bit, rolled his eyes, and walked away. 

(I know his reaction to Mark and Addison was a bit mild bit I was trying to make it so he was super happy like that one episode with the bright and shiny. Anyways, I don't actually know what is going to happen next cause I don't want this to be the end of the drama. Maybe I will have a Merder fight. We will see. But I think I might make a fluffy chapter or two for now. Also please comment on stuff. My life is boring and I need entertainment.)
