Chapter Thirty-Three: She Knows

Meredith stood there frozen to the floor in front of Addison. How had she found out about Derek? A million thoughts whirled through her head about how she had found out the details of her brief relationship with Derek.

"Ho…How do you know about Derek?" Meredith stammered.

"I figured it out Meredith, it wasn't too difficult with the way he is always hovering around you, and those looks he gives you" Addison snapped harshly.

"This is none of your business" Meredith snapped. "It must kill you to know that your fiancé broke up with you and the man you threw it away for doesn't want you either" Meredith replied callously.

"Well I hope your little fling with Derek was worth it, it must be killing Mark not knowing whether he is the father of those babies" Addison blurted out cruelly. She hadn't planned to use that information against Meredith like this, she had hoped to sit down and calmly talk but she should have known that would never happen with Meredith being as headstrong as she is.

"How do you know that? The nurses right, they just love to talk about how fucking messed up my life is" Meredith shouted to no-one in particular.

"I read your file" Addison said softly, not wanting to get any of the nurses in trouble. "I saw that you have a paternity test scheduled for next week and I put it all together from there" Addison confessed watching the pure anger wash over Meredith's face.

"What gives you the right to look at my file, you're not my doctor, doesn't privacy mean anything to you" Meredith screamed at her launching toward her.

Addison thought for sure she was going to slap her but was relieved when two strong hands wrapped around Meredith's waist pulling her away.

"Meredith, what the hell are you doing?" Alex asked her as he pulled her out Addison's office. "Are you trying to get kicked out of the program?"

"Let go of me" she screeched at him.

"What so you can go back in there and kick her ass, I don't think so Mer. As much as I would love to see that you're pregnant and an intern" Alex told her firmly leading her toward Sloan's office as he paged him there.

Mark looked at his pager as it signalled a new page received.

Come to your office, it's about Mer. Alex

Mark excused himself from his patient telling them that he would have a resident explain the procedure; he had another emergency to tend to. He ran to his office and pushed it open to find Meredith curled up in a ball on his couch sobbing

He looked at Alex for some sort of explanation. "What happened Karev?" he asked swiftly moving toward Meredith and scooping her into his arms as she sobbed. She clung to him as she continued to cry, her breathing sharp.

"I heard shouting in Montgomery's office, got there just in time Mer was about to kick her ass" Karev said simply.

"This is not good" Mark muttered half to himself. "You can go now, thanks Alex" Mark said sincerely.

"It's alright Meri, I'm here now, I need you to calm down, deep breaths" he soothed her rocking her in his arms. He knew this stress wasn't going to be good for the babies. He wondered what Addison had said to get in such a state.

"Meri what happened?" he asked once she had seemed to calm down.

"She…she knows" she stammered.

"Who knows what sweetie?" he asked confused, as he ran his fingers through her wavy hair.

"Addison knows… about Derek and the test, she…she said things" Meredith confessed beginning to sob again.

"Its alright baby, I'm here, how did she find out?" he asked unsure of how Addison would find out such things. Surely Derek wouldn't have told her and the nurses only had their suspicions they didn't know anything for sure.

"She read my file" Meredith said softly.

"She what?" Mark shrieked causing Meredith to jump.

"Sorry" he mumbled into her hair hugging her tightly to his body. "She has stooped to a new low" he said.

Meredith just nodded, her eyes drooping with sleepiness. Mark laid her down onto the couch and grabbed a blanket draping it over her. "You rest" he whispered into her ear. "I have something to take care of" he said dropping a kiss to her forehead before leaving her to nap in his office.

"Are you out of your mind?" Mark said harshly barging into Addison's office without knocking.

"Excuse me? Ever heard of knocking? I could have been with a patient" Addison snapped at him.

"You don't work here you don't have patients" Mark replied his voice rising. "What were you thinking reading Meredith's file?" he asked his eyes glaring into her.

"I knew there was something odd about the way Derek was hovering around her, I knew her file would tell me something, obviously she wasn't going to talk to me" Addison defended her actions.

"You hurt her Addie, you betrayed her trust, she still doesn't trust me completely but we are trying" Mark told her firmly.

"You're willing to stand by and watch her carry another man's children Mark?" she asked knowing that the Mark Sloan she knew would to stand for it.

"That's the point of the test Addison, to find out for sure, and yes if they're not mine I am staying with Meri, its my fault she came here and met him in first place" he said softly.

"No, its mine" Addison told him tears dropping down her porcelain skin. "Mark I was pregnant, I aborted the baby" she said softly.

Mark stared at her unsure of what to say. A million thoughts racing through his mind. "Was it mine?" he asked shocked.

Addison shrugged her shoulders. "I don't know, I just knew that I couldn't have a baby not once Jake left me" she began to cry. She looked up waiting for Mark to say something but he simply got up and walked out of the office, closing the door behind him.
