A/N: I told you guys I'd get it up today! Yay! I did it! After much debating whether or not I should make last chapter a dream, I decided against it. Somebody suggested making it Addison's dream. I tried doing that but it wasn't coming out very well. LOL. This chapter was very hard for me to write. I don't know why, but it was. Anyway, thanks for all the reviews and…on with the chapter.

Addison stared blankly at Meredith's door. It wasn't long before she started to cry, and had run off to her car. Meredith watched from her living room window as her best friend broke down. In the year or so that she had known Addison Shepherd, she had not once seen her cry. There's always a first for everything though.

Once Addison's car was out of sight, Meredith backed away from the window and plopped herself down on the sofa.

As soon as Addison got into her car, she slammed her foot on the gas pedal and darted towards the trailer. The drive that normally took ten minutes, only took five today, and before she knew it, she was in front of the trailer.

Addison stormed into her and Derek's home, throwing her purse on the sofa and dropping the keys on the countertop.

"DEREK!" Addison yelled.

When she got no answer, she walked into the bathroom where Derek was taking a shower. She flushed the toilet and waited for Derek to scream from the cold. It wasn't long before he jumped out of the shower and stood in front of Addison.

"What the hell did you do that for?" Derek snapped.

"You got Meredith pregnant. You got her pregnant and you didn't even tell me."

"I just found out Addie."

"Don't give me that crap."

"Addison, I found out a week ago, when Meredith was in the hospital. I was going to tell you tonight."

"When did it happen?" Addison looked down at her feet, scared to know the answer.

"During prom."

"You son of a bitch."

Addison walked out of the bathroom and into their bedroom. She grabbed a suitcase and started to pack her things.

"Addison, I am SO SO sorry. You have to understand Addie, it was a one time thing. I haven't slept with her since."

"Oh that makes me feel SO much better."

"Addison, please." Derek grabbed Addison's arm, turning her to face him. "I had no idea that I got her pregnant until last week. She told me they were Finn's."

"Why didn't you tell me when you found out, Derek? Huh?"

"I was scared."

"That's a bunch of bull." Addison said as she closed her suitcase.

"Meredith didn't even tell me Addison. Christina told me. If it wasn't for her I wouldn't have found out."

"I don't care Derek. You still slept with Meredith. You still got her pregnant."

"Addison…"

"I just can't believe you did this. No, you know what? I can believe it because its you. I should have expected this from you. I should of seen it coming, but Meredith? I would have never expected this from Meredith. I guess she's better for you then I thought. I can't believe I tried to be friends with her. Good bye Derek. "

Addison grabbed her suitcase and turned to leave.

"Addison, wait…"

Addison turned around and looked at Derek.

"Don't be mad at Meredith, she's been keeping this to herself so you wouldn't get hurt."

Addison simply nodded before leaving the trailer and getting into her car.

Meredith woke up on the sofa two hours later to the phone ringing. She looked at the caller ID. It was Addison, again. She didn't want to get into it with her, so she decided to ignore it, again. Meredith looked over at the clock. It was well past nine. She decided that she might as well go up to bed, so she put the phone back and shut off the TV.

Just when she got to the top of the stairs, the doorbell rang.

"Izzie, how do you manage to forget your key everyday?" Meredith laughed as she walked down the stairs.

She slowly unlocked the door, and opened it to let Izzie in, only to find that Izzie wasn't the one outside, Addison was. Meredith slowly closed the door without saying a word and walked back upstairs, where she proceeded to go to bed.

A few minutes later, she heard the front door open and close, and footsteps walking up the stairs and into her bedroom. The footsteps stopped when they reached her bed. Meredith looked up to see Addison standing over her.

"Addison, what are you doing here?" Meredith asked as she sat up in bed.

"I need to talk to you."

"No you don't. There is nothing that has to be said, okay? Nothing."

"There is everything to said."

"Addison, I don't feel well. Can you please just go home?"

"No, Mer. I can't go home. I need to talk to you."

"Well maybe I don't want to talk to you!" Meredith snapped.

"I'm not mad at you."

"Why? I slept with your husband."

"I know."

"Then why aren't you mad at me?"

"Meredith, how do you know that they are Derek's babies?" Addison asked.

"I can not believe you're asking me that!"

Meredith got off of the bed and walked to the other side of the room where she sat down in a chair.

"I just want to…"

"To make sure. I know. You want to make sure that there is no way of the twins being Finn's. Because we all know that Meredith sleeps around. Good ole' Meredith. Meredith the whore."

"Meredith…please. I just want to know."

"I think you should leave."

"Is it so much for me to want to know whether or not your babies belong to my husband?"

"Finn and I never had sex."

"Oh…"

"I think you should go. I don't think I can deal with any of this right now."

Addison nodded before walking out of Meredith's bedroom. Meredith watched Addison walk down the sidewalk and into her car. Once Addison's car had pulled away, Meredith got off of her chair, and got back into bed.

A/N: So was it any good? Yes? No? Maybe so? Please tell me what you guys think. I personally think this chapter could have been much better. But I don't know. I originally was going to have Addison find out when she was taking care of Meredith's babies and she found a birth mark just like Derek's on one of Meredith's babies, but I went with this instead. LOL. So…thanks for reading. Please let me know what you thought about it!
