AUTHOR'S NOTE This is a crossover between Grey's Anatomy and Lost…sort of. No Lost characters actually show up – it's more that they're just referenced. I wrote this a long time ago – the story takes place mere days after Oceanic 815 crashes and during the second season of GA just after the two-part episode with the Code Black (the bomb episodes) – so it doesn't take into account anything that happens in the recent episodes of either show.

I'm watching Lost on my DVR right now – please don't spoil anything that happens in the last month or so in any reviews! Thanks :-)

DISCLAIMER I don't own any of these characters.

Everything was shaking.

It happened all of a sudden. One minute everything was fine and the next he was deafened by the rattling of the walls and ceiling and floor around him. His seat trembled violently. He clutched desperately at the armrests, praying it would stop.

It didn't. It only got worse. A panicked voice came on the loudspeaker, but he couldn't make out her words. He was choking; thick black smoke rose up all around him and flooded his lungs. Hacking coughs racked his body as he gasped for fresh air. The heavy, oily blackness clung to his nose and coated his lips.

Somewhere deep in his mind, he knew that it shouldn't be getting hot like it was. That was a bad sign. But the panic was too strong. He tried to take a deep breath to calm himself and push the panic away, but choked again on the smoke. The panic completely took over. Dimly, he was aware that the heat was coming from fire and that it was creeping closer to him. Between the smoke and the fire, he would be dead in a matter of moments. He was a doctor. He knew what smoke inhalation did.

He felt himself pitching forward and braced himself. He knew what was coming. He prayed furiously and said goodbye to the woman he loved. Eyes squeezed shut, he waited for the end.

There was a horrible crunching sound and a final shudder. Everything went black.

Derek Shepherd woke himself up with a shout. He was covered in sweat and the sheets that were wrapped tightly around his chest and legs were soaked with it. He scrambled back against the headboard, wincing as the sheets were pulled even tighter around his body, pinching and cutting off his circulation. His breath came in ragged gasps as he blinked in the dark. He was cold now, but the memory of the flames licking his skin would not go away.

It took a few moments for his red-haired wife to wake up at his distress. She blearily rubbed her eyes and squinted at him. "Derek?" she asked. "What's wrong? Did you get paged?"

"No." He untangled himself from the bedclothes and paced restlessly around the tiny bedroom. "Go back to sleep, Addison."

But it was too late. Addison was fully awake and knew that Derek was deeply troubled. "Don't give me that. Something's really wrong!" She too slid out of bed and tried to calm him down. "Derek, stop. Please, tell me what's the matter."

He stopped and looked at her. "I need to go."

"What do you mean, go?" she demanded. "It's three in the morning! Derek!"

But he wasn't listening. Addison's protests fell on deaf ears as he climbed into the shower, but had to keep the water cold because the heat was still so vivid from his dream. His scrubs were at the hospital so he pulled on faded grey sweatpants and a sweatshirt that used to belong to Meredith.

Addison knew that the sweatshirt wasn't his and she had a pretty good idea where he had gotten it. Familiar jealousy boiled in her veins. "You're going to see her, aren't you?" she asked.

Derek didn't answer. He continued to get ready, dragging a comb through his dripping black hair. Addison shook her head. "You're going to see her just like you did last week."

He turned to her, an angry flash in his eye. "Last week she was seconds away from being blow up. And no, I am not going to see her. I'm going to the hospital. I need to clear my head."

His words did nothing to reassure her. He felt bad about that, but was so unsettled that there wasn't anything he could think of to say. Instead, he opted to give Addison a kiss on the forehead and whispered, "I'll see you at work."

Addison stood and watched him leave, a single tear escaping her control before she turned and went reluctantly back to bed. The bed felt cold without him.

The sky was an inky black as Derek took the ferry into the city. Most of Seattle was still asleep and the lights of the metropolis were muted. When he finally reached Seattle Grace Hospital, only a handful of rooms glowed brightly in the pre-dawn darkness.

Derek made his way up the stairs to the break room. Lack of sleep made him drag and the silent ferry ride had calmed his nerves. There were still two hours before he had to be on duty. He hoped maybe he could fall asleep again.

He pushed the door open and flooded the small room with fluorescent light. A blonde woman sat up on one of the beds, blinking in the brightness. She squinted. "Derek?" she asked.

Derek's heart sped up at the sound of her voice. "Meredith. What are you doing here?"

She stretched and yawned. "Izzie and I were on call. We've been napping in turn."


They stood in silence for a minute. Finally, Meredith looked at him closely. "Are you okay?"

He nodded. "Yeah." Then he laughed to cover the sudden tears that had gathered in his eyes. "I had a feeling."

She stood up. "I've had those before."

"I remember. Didn't work out too well as I recall."


Resisting the urge to reach out for her, Derek asked, "How are you?"

"I'm fine." But the tone of her voice spoke volumes. "So tell me about your feeling."

Derek sat down on the metal-framed bunk bed. "It was a dream. Was yours a dream?"

"Mine wasn't a dream," Meredith said.

"Well, mine was a dream. I was in an airplane and suddenly something happened. There was fire and this thick black smoke. I was choking on it. Everything was shaking."

Meredith waited for him to continue. "Then?" she prompted.

He shrugged and shook his head. "Then nothing. I woke up."

"Derek, it was just a bad dream."

"Yeah." He looked up at her, his expression serious. "But now I have a feeling."

She nodded. "Now you have a feeling." She sat in the rickety chair by the door. "Is there anything I can do?"

Just then, the door opened. "Mere, are you up yet? I'm dying to sleep." Izzie Stevens came into the room, but froze when she saw Derek on the bed. "Dr. Shepherd!"

He stood up quickly. "Dr. Stevens."

"I, uh, didn't know you were here," Izzie said. "I'll just, uh, leave you alone." She ran out and shut the door behind her.

"Izzie, wait!" Meredith called. She looked back at Derek. "Maybe get some sleep. It might help make the feeling go away." Then she opened the door and started after Izzie. "Izzie, it's not …"

Derek groaned and fell face-first into the pillow. It would be a long day.
