Alright, so this chapter was a little hard to write, but I hope you all enjoy it!

"Who are you?" Addison asked loudly, hoping Meredith would hear what was happening and use the upstairs phone to call for help.

"I don't have time for questions," he said as he reached into his jacket pocket and pulled out a roll of tape. "Now don't take this the wrong way, I don't have anything against either one of you. But I don't think I trust you enough to not run off and call your big tough boyfriends to come to the rescue. So even though I hate to do it…I'm going to have to keep you quiet."

Beth pulled on Addison's hand as they slowly started to edge towards the door. "Don't try and get away," he sighed. "I'm not here to deal with you, and if I have to waste my time, I'd get very…angry. So let's just cooperate here, and neither of you will get hurt. Okay?"

He reached out to grab their joined ands, clutching them tightly as he ripped some tape off the roll, covering each of their mouths before anything else. "Can't have you screaming for help."

He quickly taped them both into one awkward position, hands tied together behind their backs and both of their feet together. When he stepped back to look at his work, the girls cowering together in the corner of the living room, he smiled and moved towards the stairs. "If you'll be so kind as to excuse me, I've got some business to take care of," he said as he approached the stairs.

Meredith turned off the sink and smiled at herself in the mirror. She felt good about herself. For the first time since this whole thing had started, she felt good about herself and she was really looking forward to a night with Derek, to sex and wine and…him. They'd been constantly together for the past couple weeks, scared of what might happen, but they hadn't been themselves. Instead, they'd turned into some weird pod people who were afraid to live. But Addison was right, tonight she and Derek needed a night to just be them.

She smiled as she heard footsteps on the stairs. Apparently Addison had finally let Derek up to her. She'd heard some loud voices over the running of the water as she'd washed her face, and she laughed slightly, knowing that Addison would have gone to great extremes to make sure Derek didn't get to her until she was ready. Her best friend was nothing if not bossy.

She looked in the mirror one last time, fluffing her hair and adjusting the lingerie before she turned to the door. She briefly wondered why Derek hadn't already knocked and told her to come out because she already looked beautiful, but she shook that thought out of her head. He was probably just hanging his coat in his closet or something.

"Hey, Der…." She said as she opened the door, leaning against the frame for a moment before terror ran through her body. She straightened quickly, crossing her arms over her chest and glanced down the stairs. "Dr. Brown," she said with a shaky voice. "What…what are you doing here?"

"Oh Meredith," he breathed as he approached her. "You look…stunning. I knew you felt this way about me. I knew it, you were just pretending to love that husband of yours."

"I….what?" she asked, stepping back into the bathroom as he advanced towards her. "What did you do to Derek?"

"He won't get in our way now," Dr. Brown said, smiling as he stepped into the bathroom as well. Meredith gasped as she backed into the wall, her eyes full of panic as she realized that there wasn't anywhere else for her to go. She was trapped. "We can leave, Meredith. Right now, we'll leave, and be together. I know you want to."

"I don't want to," Meredith argued, her arms wrapped protectively around herself. "Where's Derek?"

"Don't lie to me," Dr. Brown snapped. "I hate it when people lie to me. And I know you don't love him Meredith. I watch you. When you're with him, you're picturing me. I know you are. That's why I sent you all those pictures. So you can know that it will work for us. I promise, darling." He reached out to touch her cheek, but Meredith pulled back, trying to squirm from his grasp.

"Let go of me!" she shouted.

"I can't do that," he shook his head. "We're together now, Meredith. Forever."

"No!" she shouted. "You can't make me do anything."

"Hmmm," Dr. Brown nodded as he reached into his pocket, gently pulling out a gun. "I think I can."

Meredith froze as she stared at the gun in his hand. "Where's Derek?" she repeated evenly, not sure she wanted the answer as terror ran through her veins.

"He's out drinking," Dr. Brown rolled his eyes. "Honestly, Meredith, you'd think that a woman as smart as you wouldn't stand to have an alcoholic as a husband."

"You're crazy," Meredith snapped. "The police are watching. And I'm not going anywhere with you."

"I think you will," Dr. Brown nodded. "Because those friends of yours are downstairs. And if you refuse to come with me, I might get angry. And who knows what I might do when I get angry." He looked down at his gun, examining it closely before he aimed it steadily at the wedding picture on Derek's side of the bed. "So, Meredith," he said. "As beautiful as you look right now, I'm going to need you to put on some clothes. And then we're going to make a little stop at the bar so you can break up with that loser of a man that you call a husband. And then…then our life can really start."

Meredith stood firmly in place, making no move to get dressed as he stared at her. "Now Meredith," Dr. Brown sighed. "I told you…you're going to have to cooperate. I hate to do this, my love, but I'm going to have to ensure that you do everything I tell you." He raised the gun to aim at her head and she swallowed hard as fear flashed in her eyes. "Get dressed."

Meredith trembled as she reached into her dresser for a pair of jeans and a sweater. She moved slowly, trying to gain more time to figure out what the hell she was going to do. She had no idea how she was going to get out of this one, but she knew she had to cooperate with him until she figured something out. Now that there was a gun involved… she couldn't let herself be responsible for anyone she loved getting injured.

"Alright," Dr. Brown said, tucking the gun back into his jacket pocket and reaching for her hand. "Now we're going to go for some drinks. Or…you are. And I'll be listening from outside, so you better not do anything stupid," he said as he shoved a microphone into her pocket. "I'm going to tell you exactly what to say to that loser, and you're going to say it. Understood?"

Derek looked up from his beer when he heard the bell above the door ring. His eyes widened as he saw Meredith enter, and he immediately knew something was wrong. "Mer," he said, standing to meet her. "What are you doing here?"

"Um…" Meredith swallowed hard, and he could see tears filling her eyes. "Derek…I'm leaving."

"You…what?" Derek asked, reaching out to grab the table as his world spun out from under him.

"I can't do it," Meredith whispered, feeling herself get sick to her stomach as she said the words. "Med school's too much and I gave up too much for you. It's just not worth it, and I'm leaving."

"No," Derek said, shaking his head as he reached out to her. "Meredith, no. I know you. You love med school. And you would have hated Seattle, you said so the other day. And…you love me."

Tears streamed down Meredith's cheeks. "I can't do it, Derek," she recited. "I need to leave." She swallowed hard as she ran her fingers along the microphone in her pocket, knowing that Dr. Brown was listening to every word she was saying. Her brain raced for some sort of way that she could tell Derek that she was in danger. Finally, she placed a hand on her shoulder and pressed a gentle kiss to her cheek, quickly whispering, "Dr. Brown," before she turned and walked out of the bar, wiping at the tears on her face.

"What the hell was that?" Mark asked as Derek turned back to the table, tears swimming in his eyes.

"She's….gone," he whispered. "Meredith's gone."

"I don't believe that," Nathan said. "That girl loves you."

"She used to," Derek whispered. "She said I'm not worth it."

Mark frowned. "Something's going on," he said. "Grey would never leave you."

"Well she has," Derek snapped, reaching for his beer and downing it. "So now my life is a fucking mess."

"What did she say to you?" Nathan asked. "When she kissed your cheek."

"She said…Dr. Brown," Derek sighed. "I don't know what that means. She would never sleep with a professor. I know she didn't leave me to be with…." His voice trailed off as realization dawned on him, and he slammed his beer on the table, grabbing his jacket as he sprinted out of the bar. "Meredith!" he shouted as he ran into the cool night air. "Meredith, where are you?" He looked up and down the street, receiving strange looks from the few passerby that were lingering on the streets, but none of them were his beloved Meredith. With fear in his heart, he took off in a sprint towards his apartment, determined to find his wife before something awful happened. As he ran down the road, he failed to notice the dark alley, where his wife was being held tightly against her will, a hand clapped over her mouth as she tried to scream for him.

"Fuck," Derek muttered as he dug into his pockets, realizing that his keys were gone.

"What's going on?" Mark asked as he and Nathan ran up beside him.

"My keys are gone," Derek said. "Someone took my keys."

"Calm down," Nathan said, pulling his own keys out of his pocket. He quickly unlocked the door and Derek sprinted for the stairs, the other two close on his heels. When they reached their apartment floor, all three of them stopped short when they saw the door to Derek and Meredith's apartment wide open. They glanced at each other for a moment before cautiously moved towards the open door. When Derek finally stepped through, he felt himself want to throw up as he saw Beth and Addison taped together on the floor of the living room, tears streaming down both of their faces. He quickly moved towards them, gently taking the tape off of Addison's mouth before he turned to Beth.

"What the hell happened?" he demanded as Mark and Nathan ran to help him undo the tape, the three of them making quick work of freeing the girls.

"Derek, he's got her," Addison said from her place in Mark's arms. "I'm sorry. He just came in and he had a gun and he told her that she had to tell you she was leaving you because otherwise he would start shooting. Derek, I'm sorry."

"Where were they going?" Derek asked. "Did he say anything at all?"

"No," Addison whimpered, burying her face in Mark's jacket.

"We should go to the police," Nathan said, his arms wrapped tightly around Beth.

Derek was out the door before anyone could say anything else, and he sprinted down the stairs to the cop car that was sitting outside his apartment building.

"Detective White," he said, banging on the window. "He took her. What the hell were you doing? You're supposed to protect her!"

Detective White sighed as he stepped out of the car. "Mr. Shepherd," he said. "You wife left the building, but she wasn't struggling. She was smiling, even holding this man's hand. In my experience, people in danger generally don't do that."

"She was faking it," Derek snapped. "And now, thanks to you and your lazy ass, my wife is out there with the psycho who's been watching her for weeks."

"Shit," Detective White sighed. "Alright, you've got a name on this bastard?"

"I…I don't know his first name," Derek said softly. "Dr. Brown. He's a professor of neurology at Columbia University, and he works at New York General. He's been obsessed with Mer and…oh my God."

"Alright, Mr. Shepherd, calm down," Detective White said. "I'll call in for his information, and in the mean time we'll head over to his office, see if there's anything of significance there."

Derek collapsed onto the curb, burying his head in his hands as he listened to Detective White call for back up and information on Dr. Brown. He had no idea ho he'd possibly let things get this bad, but now all he wanted to do was hold Meredith in his arms and never let her go.

"Alright, let's go," Detective White sighed as he moved to turn the car on.

"Wha…you're letting me come with you?" Derek asked.

"You obviously aren't going to calm down if you're alone," Detective White said. "I know how much you love your wife. And….I'm concerned for your safety. So you're safer coming with me."

"Oh," Derek nodded, realizing that although he wasn't supposed to come along with the investigation, Detective White was going to allow him to anyways. "Thanks."

"Looks like they're here before us," White sighed as he pulled up to the neurology building. "Now, you've got to listen to me. I'm doing you a favor by letting you be here. You stay quiet, you stay in one place and you do whatever any police officer tells you. Got it?"

"Yeah," Derek nodded. He followed White out of the car and over to the steps of the building.

"What have we got?" White asked.

"Seems the doc's in there," another officer sighed. "We've got a camera that shows he's got a girl in there with him. We're just trying to get a hold of the situation."

"What the hell do you mean?" White asked. "Get her out of there!"

"It's not that easy," the officer sighed. He glanced at Derek before he leaned forward and pressed a button on the tape recorder in the back of the van.

"And if anyone comes near here….I'll shoot her!" Dr. Brown's voice said from the speakers. "You hear that? Anyone comes close to the building, she dies!"

White sighed as he turned to stare at the building. "Shit," he sighed. "What are we going to do?"

"What the hell is he doing here?" a voice suddenly boomed from the window. Derek looked up to see Dr. Brown standing at the window of the only lit room in the building. "I want to see him." His voice boomed from a megaphone, and Derek swallowed hard, knowing he was talking about him.

"I'm going in," he said as he moved towards the door.

"Stop right there, Shepherd," White demanded. "You're not going in there."

"Derek….." Meredith's voice suddenly whimpered through the megaphone, causing Derek to shake his head and move towards the door.

"She needs me," he said. "I'm not going to stand around and wait for her to get hurt."

"Derek!" White shouted as Derek ran into the building. He turned to look at the officers who had set up camp outside the white van parked at the entrance. "Get some bullet proof vests on and get in there. Now."
