Author's Note: We're slaves to your opinions, and we need reviews. Ok. It's been a while. But we started college, but we promise we'll be updating this, "Sound and Fury" and "The Best Laid Plans". At least as much as possible. Anyway, REVIEW or we'll kill ourselves.

Things were bad. Meredith's back was pressed into the cold tile of her shower, water was streaming down on her, her legs were hooked around Derek's waist, and she was alternately clutching his shoulders and the shower head.

And that wasn't even the bad part. The bad part wasn't that she was having illicit but amazing shower sex with Derek. The bad part was that she didn't care what she was doing. She was like a maniac, out of control, and in a full on Derek haze. She was questioning everything she ever felt for Paul.

That was the bad part. Not the shower sex induced orgasms. Those were definitely okay.

"How's the Big Banker's trip the mother country?" Derek asked Meredith, as they stood outside her house later. Meredith rolled her eyes.

"It's fine. He had a meeting with a few members of Parliament today, and tomorrow-" she stopped. "Why am I telling you this?"

He shrugged and grinned at her, is lopsided, cocky, you know you want me grin. "You tell me." He said, before getting into his car and driving away. "On call tonight?"

Meredith nodded. He grinned again, and she just shook her head and watched him go.

Derek pulled the car into the lot at Joe's and sauntered inside. He saw Addison, sitting at the bar. "You're late." She chided as he slid onto the seat next to her.

"I got held up. Sorry." She gave him a look that clearly conveyed she didn't need any more details, and checked her watch.

"Hot date?" Derek asked. She blushed, and turned her stool to face his.

"Can I tell you something? Without repercussions?" He nodded. "I'm here with Mark." She blurted out. "I mean, it's not, we only met after you left. He came to help me help you."

Derek digested it and gripped her shoulder. "Good luck with that one, Addison." She smiled tentatively and laid the papers on the bar. They both signed this time, and they smiled at each other afterwards, knowing it was right.

"Mark and I both know Paul. From the hospital." Addison said, her voice low. Derek raised his eyebrows. "I'm going to make a call and pull as many strings as I can, okay?"

"Thank you." It was the first connecting moment they'd shared in years.

Meredith woke in the on call room to the sound of her pager going off. A few car crash victims later, she was shuffling down a hall way when she shuffled into Derek.

"Hi." She said.

"Hi." He said wearily.

She eyed him suspiciously. "You don't look happy." The truth was he had left Joe's and started to worry. Any reason fro Meredith's fiancé to be at a New York hospital could be some reason that would end up hurting Meredith.

And then he had started to question himself. What if this was fruitless? What was he doing?

"I want you to tell me what we're doing." He said before he could stop himself.

She looked at him in a mixture of apprehension and awe. And then she shrugged. "Honestly, I don't know. You're larger than life to me Derek. One day, you just drop off the face of the Earth, without looking back once, and the next day, you're back at work like nothing ever happened."

"That doesn't explain why we're sleeping together." He said. "I want to know why."

She smiled sadly. "You want too much Derek."

"That's not fair, Meredith."

"Not fair?" she said, laughing bitterly. "You're the one who came back here. You tell me why you did that, and I'll tell you everything you want to know."

"I don't know why, Mer. I had to get out of New York. I got a call from Burke, he said you were getting married, and here I came."

"That's not fair Derek." She mocked. "That's not enough."

"Will anything I do for you ever be enough, Meredith?" he shouted angrily.

She just looked at him. "As soon as I have a reason to believe it won't just let me down." She turned on her heel, and walked away.

Addison checked her watch as she and Mark returned to the hotel. "Go ahead, inside. I need to make a phone call."

"The phone call?"

She nodded. "It's only nine in New York."

She pulled her cell phone out of her pocket and pressed speed dial one. "Hi, this is Dr. Addison Montgomery Shepherd. I need to speak with Dr. Badley."

She waited until she heard a hello on the other end of the phone. "Hi. Chief." She said, "It's Addison. I need a favor."

"What kind of favor?"

"I need to know why and for what we're treating Paul Williams."

"Addison, why in the hell would you even ask me for that? You know I can't-"

"But you can." She said quickly. "I'm his fiancé's ob-gyn. She's pregnant, and having unusual symptoms and Mr. Williams won't disclose his medical records. That's why I came to Seattle. It could become a legal issue." She realized she was babbling, and stopped.

"You have a court order?"

"That's where the favor comes in. We don't want to destroy the couple over this. All my patient wants is to treat the baby."

There was a sigh on the other end of the line. "All I'll tell you is he's been in the Center For Infectious Disease every month."

"Thank you, Dr. Badley."

Infectious disease. Derek wasn't going to like that.

Derek was going crazy. It had started to rain, and there had been a huge electrical fire, thanks to the lightning. She had been outside, and he had been there to see her, running inside, soaking wet, top sticking to her perfect body.

It had made him dizzy. He vaguely wondered if he really was going insane. He was a man possessed by lust and jealousy. He wanted Meredith in the worst kind of all consuming way. He replayed their trysts in his head. He saw her everywhere.

And then there were the times he thought about Paul, and his aristocratic good looks, with his hands on Meredith, touching her, having sex with her. It angered him in a way he didn't know was possible, and it scared him. Derek lingered on the edge of something dangerous all the time, and tonight was no exception.

Meredith too, was angry and dazed in her own right. She was confused, and scared and pissed. Paul had called her from London to say he wouldn't return until the next night, the night of their rehearsal dinner. She ran into the hospital, wet, and on the edge. She fixed Derek with a smoldering look and made a point of brushing against him when she walked past.

Inside the hotel room, Addison picked up her phone again. Infectious diseases. "Hi, this is Paul William's assistant. I'd like to know if there are any prescriptions for him I should arrange to be picked up."

There was a bored sigh on the other line. Finally, she heard, "Yea, this month's Fortovase will need to be picked up by tomorrow, like I told you last time you called."

"Right, sorry. I lost the memo. Thank you." Addison stammered, her brain going a thousand miles a minute. Fortovase. The hospital had gotten a memo about it in March. Fortovase.

"Jesus." She said out loud. Mark came out of the bathroom, looking at her quizzically.

"Find anything?"

She turned to him, frustrated. "What does Fortovase treat?"

Mark's eyes widened. "Why?"

"Paul Williams is taking it."

"Addison," Mark said softly, "Fortovase is the new preferred treatment for AIDS."
