Derek sighed and stood next to Cristina in the backyard of Meredith's house. "It's going to be a great party, Cristina." He said. Derek knew it was as good as over. The party Cristina was throwing for them was in a few hours, the next day was the wedding rehearsal, and after that, he'd lose her.

Cristina glanced over at him. "Dr, Shepherd," she ventured, "You know this isn't what I want either."

"Call it karma." Derek mused.

Cristina frowned at him, wishing she knew what to say. "I'm sorry." She went with.

"Don't be. I really don't have anyone but myself to blame. I'm the one that left, remember?"

"How could I forget?" Cristina asked, smirking. "But, Dr. Shepherd, listen to me. I shouldn't be saying this, as the maid of honor and all that, but um, I wouldn't say it's over till it's over."

Derek raised his eyebrows. Cristina took a breath. "She's not Meredith without you. Don't give up on her."

"D0 you know where she is?"

"At the airport, picking up Paul."

He kissed her as he climbed into the passenger side of her Jeep. "Hello gorgeous." He chirped in his accent. "Miss me?"

She smiled. She was going to confront him now, in this little box of a car. Where he had no where to run, and she had nothing to lose. "How was New York?" she asked.

"London." He corrected.

"New York." She countered. "The St. Regis, I believe was where you were spotted."

He closed his eyes, but didn't say anything. So he wasn't going to volunteer the information. "You're very lucky." She said.

"Because you're going to forgive me." He said, trying to sound confident, but coming out more scared.

"No. You're lucky because I don't have HIV." She said, dropping her bombshell. And she didn't. Addison and Mark had been amazing pinnacles of calm, taking her blood, running the tests, and not treating her like a patient.

Her fiancé looked like he was going to be sick. "How do you know that?"

"It doesn't matter how I know," she said, determined to remain calm. "What matters is why you didn't tell me."

"I just found out." He whispered. "I just found out."

"That's bullshit and you know it."

"It's not. I can prove it, Meredith, I swear it."

She narrowed her eyes at him, ready to scream, ready to kill him, ready to call the whole thing off. But when she saw he was crying, she simply pulled the car to the side of the road.

"Let's talk, Paul."

5:58 PM

Derek knocked on the door of Meredith's bedroom. "Mer?" he called out.

She opened the door, already wearing her dress. Derek's eyes wandered over her, and she didn't know what to feel in reaction to that.

"I really don't know if we have anything useful to say to each other, Derek."

"Anything useful to say? That's all I get? What is this Meredith?"

Her eyes flashed. "That's all you get? All you get? What about what I get, Derek? What about that? What about what I got when I called the hospital, looking for you? What did I get then? And what about now? When I'm finally ready to let go, what do I get?"

"It's not like nothing happened between us since I've been back, Mer. If we could just talk about things, then maybe…" he trailed off.

Meredith laughed bitterly. "Then what? We could sail into the sunset together? What do you want me to do Derek? Take you back and wait for you to leave again?"

"Why are you pretending I don't mean anything to you?" Derek demanded.

"Because you don't get to waltz in and out of my life, dictating it as you come and go!" she shouted.

"That's not fair, Meredith."

"You want to talk about fair? You had sex with me, Derek. And you told me that you loved me. And then you left for New York, without saying goodbye! That's not really fair either. And now that it suits you, you expect me to pick up where we left off?"

Derek's jaw clenched, because he knew she was right. He was being selfish, and irrational, but he couldn't control himself. "I know you still love me, Meredith!" he exploded.

And then, Meredith snapped. All the pent up anger, frustration and sadness she'd been keeping inside of her for the past few days came out. "What is love Derek?" she screamed. "What is it? What if you don't get to be with the one? What if the one fucks that up, and you just have to settle?"

"You can't believe that." He said.

Meredith slammed her hand into the wall. "Damn it, Derek! You can't even begin to imagine how hard I crashed when you left."

"I'm sorry!" he shouted.

She laughed. "Oh you're sorry?" she spit out. "Well, thanks, Derek. That really makes up for the last three years. I'm so glad you're sorry."

"So I come back and you'll just fall into bed with me?"

"If you're so opposed to sex, enlighten me as to how we had it, Dr. Shepherd."

Dr. Shepherd. She said it coldly. He was as angry as she was now.

"You weren't exactly saying no to me, Grey."

Meredith threw her hands in the air in desperation. "Because I can't say no to you Derek. Because you control my life, and my moods and my actions from three thousand miles away!"

"So it's my fucking fault, then, isn't it Mer? You get to be set up to have a picture perfect marriage with Mr. Billionaire, and I'm the fucked up asshole who wants to destroy it all."

He walked a little closer to her. "Why, Meredith? Paul not as good?"

She didn't know what to say to that. Of course he wasn't as good. No one could compare to Derek, on any level. But she didn't say that. She wanted to hurt him the way his presence was hurting her.

"At least I love him." She hissed. Derek recoiled like she'd slapped him. Meredith almost wished she had, anything would have been better than saying that.

"But you're sleeping with me," he shouted. "So what does that make you Mer?"

She hated what he was implying. She really hated him at that moment, but she hated herself more. She hated this fight, the way they were screaming, the way they sounded. She hated that she wanted him, that they were still doing this to each other.

So she screamed. Just let out sound. "Shut up!" she shouted, one of her fists connecting with his shoulders. She had been aiming for his face, she was pretty sure. "Look at me Derek. I'm nothing!" she was screaming and shaking, and he wasn't backing down.

"I am a self destructive shell of a person. I'm fucking numb, Derek, okay? You left and I shut down. Seeing you in my kitchen was the first time I can remember feeling anything, except cold, numbness. You did this to me Derek! You made me like this! I can't feel anything. Except for you!"

She was bordering on hysterical and still really angry. Derek was seething, and he couldn't listen to her anymore, because it would kill him to hear what he did to her, so he grabbed her by her wrist and pulled her to him. She crashed into him roughly, and he kissed her.

They were lying on her bed, clothes partially discarded when the last half hour sunk into his brain. Something told him this was a bad idea. "Meredith…." He said, not bothering to hide his anger.

She unhooked her own bra. "Shut up, Derek."

"I really can't stand you right now." He spit out at her.

"The feeling's mutual sweetheart."
