Disclamer: I don't own Doctor Who or Grey's Anatom did I probably wouldn't be here. All the stuff mark Mark and Lexie say in the dream are direct quotes from the episode 'Flight' Again I own nothing just the story.

Authors note: Sorry for the rewrite, but I just watched the new episode of Grey's and I think the fact that SPOILER! –Mark dies is very important, and will help me through the writer's block I've been having.

"Doctor?"

The Doctors face appeared from behind the console of the Tardis, his brown hair slightly ruffled. "Yes Pond?" he was clothed in his regular outfit: A faintly striped buttoned shirt, a brown tweed jacket and a bowtie.

"Is this light supposed to be doing that?" Amy pointed to the pulsing purple light on the Console.

The Doctor came around gazing at the light in interest. "hmm. Purple, don't think I've ever seen purple before. Red, red I've seen, red is bad. And blue! Blue is interesting so…"

"Purple is badly interesting?" Rory said from where he was leaning against a railing.

"Correct! Or interestingly bad both of which I must investigate."

He reached up to the TARDIS screen, eyeing the information on it with a startled expression.

"Doctor?" Amy said once again when he was silent for a few moments. Probably the longest he'd ever been silent since she'd met him. "What is it?" Brownish gaze was trained on him worriedly.

"Someone I haven't seen for a long time." With that he started pulling the TARDIS controls, moving fast like an excited child. "To Seattle!" He declared.

Cue theme music! lol that's exactly what would happen if this was a really a doctor who episode

Somewhere in seattle….

"Mark, I'm dying. I am. Tell Meredith that I love her and that she was a good sister and please tell my dad ..." As Lexie says this this my heart twists.
"You're not dying. You're going to be fine."
" Hold my hand."
" I'm not holding your hand because you're not dying."
" Hold my hand."
" No, you're not dying. Do you hear me? You don't die today!"

I struggle to lift the debris of her but even as I do I can see it's hopeless. Kneeling back down, I hold her hand.

"I love you."
" You don't have to say it just because ..."
"No, I love you. I've always been in love with you. I will always be in love with you. I love you which is why you have to stay alive. We're going to get married and you're going to be an amazing surgeon and we're going to have two or three kids."

She smiles but I can see her struggling to breath. No Lexie! You can't die!

' So, Sofia can have siblings?"
" Yeah, a sister and two brothers."
" That's nice."
" We're going to have the best life Lex, you and me. We're going to be so happy so you can't die, ok? You can't die because we're supposed to end up together. We're meant to be."

"Meant to be."

Mark Sloan opened his eyes. When he looked around, he was confused. He wasn't at home, he knew because Sofia's crying hadn't waken him up, but then where was he? It took him a moment, but everything came rushing back, the plane crash, Lexie, his heart… Then the dream, where he'd seen his whole life, over and over, like a movie playing in his mind, the good, the bad, the incredibly bad.

At least he was alright now. He swung his leg over the side of the hospital bed. It was after hours, and everything was mostly quiet, besides the footsteps of a nurse or doctor behind the blue curtain.

"Seattle Grace, Mark Sloan is back!" He pulled aside the curtain, startling a woman who was rushing past.

"Do you know where I can find Callie Torrez?"

The woman, evidently a nurse, just sighed. She seemed to be looking at something behind him. "Ma'm?" He pulled one of those charming smiles, the kind he knew made women swoon. But it didn't seem to have an effect on the nurse, who just walked away, nuttering something.

What-? Mark turned around, not comprehending what he was seeing. It was him. Still in the hospital bed. He was deathly white, not plugged up to anything, like… A body ready for the morgue. This was impossible. He couldn't be dead. Lexie wasn't here. If he was dead, then he would see her, hear her voice again. He was dreaming. That was it, still dreaming. But when would he wake up?

The Seattle Grace Morgue…

Bang, Bang. Bang! Grace looked up from her work, startled. Being Seattle Grace Mercy West's leading Mortician she wasn't used to hearing loud noises while she worked.

"Very funny!" She called irritably. It seemed the only times surgeons came to visit her was to bring her dead bodies or to play tricks. Just because she dealt with Cadavers didn't mean she didn't like company once and awhile. Her voice echoed off the metal shelves, but otherwise nothing.

Bang, Bang, bang!

Rolling her green eyes, she got up approaching the source of the noise. It was one of the shelves, number 42 to be exact. Reading the label she stepped back. Lexie Grey. Everyone knew the story of this one. No one in the hospital would be that cruel. But then what-? Grace reached her hand on the shelves handle, unlocking the door with the key she kept on her wrist and pulling it open.

"Thank God, I thought no one would hear me!" Lexie Grey swung her legs over the side of the shelf jumping the short distance to the floor. Her shoulder length dark brown hair was slightly messy, which could be expected from someone who should have been dead.

Grace stood there dumbfounded. "Y-your supposed to be dead."

"oh right, um… Lazarus Syndrome?" She said coming up with something quickly. Having a photographic memory comes in handy.

Am I still Lexie? She looked down at her hands felt her hair. "Extremely delayed regeneration, yet no change in appearance." She said mostly to herself. This had only happened once, when she'd been shot saving her father. She'd only healed, not regenerated."Do you have any clothes? I can't really go out like this." Her attention went back to the extremely confused looking Grace.

"S-sure in the closet."

Lexie smiled. "Make sure it's something nice. I'm going to Joe's."

Can you guess who Lexie really is? If you do one of your OC will appear in the next chapter
