Dean stared at her, Rose Tyler. His and Sam's childhood friend. She was...he shook his head, whatever she was, it couldn't be human not anymore. No human could fall from a fifteenth story window and survive nearly unscathed.

"What are you Rose?" He asks, his hazelish green eyes narrowing.

"I don't know what you mean boys." She answers in a soft tone.

"How did you survive that fall?" Sam questions, his head tipped to one side. "Maybe you're lucky or maybe you're not human."

"Maybe you're an angel. Maybe you've always been an angel." Dean muses.

"Why would an angel be looking for the Doctor?" Sam asks more to Dean than Rose.

Rose sighs. "There was a war. He and I….were I found him again but we had to be separated once more." Rose says, her voice quiet and sad, filled with old pain. "Look, all I want is to be with the man I love." She continues.

"Since when do angels fall in love?" Dean asks, his brows scrunching in confusion.

"Perhaps that's a question you ought to ask Castiel." Rose answers.

"Cas? What does Cas have to do with anything?"

"He has nothing to do with the Doctor but everything to do with your question of since when do angels fall in love."

Dean frowns, his nose wrinkling. "I don't get what you mean. What does my question have to do with Cas?"

Rose smiles and shakes her head. "Dean Winchester, are you really that oblivious?" She sighs. "That angel or man has given up everything, done anything to keep you safe. To make sure those eyes of yours don't get more broken and pained."

"What?" Dean asks, more confused than ever.

"Rose sighs again and shakes her head. "Nevermind. Please help me find the Doctor. I need him, I've survived without him for…."She trails off. "For far too long. I need him back."

"Of course we will." Sam chimes in, giving Rose a kind smile.

She gave him smile back. "Thank you. You have no idea how this means to me." She continued in a whisper. "How much I've missed him all these years."

"Rose, just how many years has it been since you've seen the Doctor?" Sam asks

She frowns, slender fingers tapping her chin. "Well for me, about 400 years but for him...only 200." She answers after a moment.

Dean's eyes widen. "That would make you… what? 422?" He questions.

"Yes, I suppose it does." Rose says her hazel eyes sad and far away.

"How is that possible?" Dean wonders.

"Something happened to me while I was travelling with the Doctor. I-I had to save him and in the process there was an incident which over the years has turned me less and less human. I can still feel and love...and well I'm still human in that sense. But biologically, not anymore."

"Interesting." Sam muses.

Rose just nods, her hazel eyes sad and distant.

"Hey, it's going to be alright. I promise, we will not rest until we've found a way to get you back to him." Sam says kindly, a fierce conviction in his voice.

She gave him a sad smile. "Thank you Sam."

He nods at her, giving her a smile back then turned to Dean. " we're going to need Sherlock. If anyone can find the Doctor, it's him."

Dean sighs. "The guy annoys the crap out of me, but you've got a point. Cas can help too."

"Alright. I'll call Sherlock. You can contact Cas. He listens to you." Sam says and walks out of the room as he pulled his phone out of his pocket.

Deans nods and pulls out his phone too, quickly dialing the number he knew by heart. It begins ringing. A moment later, he answers. "Dean. What's wrong?"

"We need your help Cas. Our childhood friend, Rose...she needs help getting back to the Doctor."
