The Secrets of Sarah Smith

Sarah Who?

The next morning The Doctor and Sarah had landed in Clara's flat tucked away in her bedroom as usual. The Doctor was writting in Gallifreyan on his black board that he'd taken down to the main part of the console room and Sarah was sat on a desk chair on the upper levels reading a book on medival castles, She was spin round her the chair slowly as she read.

The Doctor seemed to be getting restless. They had been waiting an hour and Clara still hadn't came into The TARDIS. He was just about to go check on her when the doors opened and in walked Clara looking just as beautiful as he remembered with her large brown eyes and soft brown shoulder length hair. Sarah shouted a quick "Hello" from the upper levels before turning back to her book.

She was wearing a small pair of denium shorts that made her legs look like they went on forever to her red ballet pumps, she wore a puffy short sleved red and blue blouse tucked into the shorts and she had a pair of sun glasses on her head. The Doctors mouth pooled and he licked his lips. His brain felt like it had malfunctioned. Clara came to stand beside him smirking at him.

"Aren't you going to say hi?" Clara said in a flirty way raising one eye brow at him. Damn she'd noticed him looking at her, he was never going to live that down

"You planning on going to a beech?" The Doctor snapped trying to cover his tracks turning back to his blackboard. He was genuinly surprised his voice still worked.

"Its boiling out there" Clara snapped back her arms folded on her chest in annoyince. The room was silent for a moment.

"Doctor? why do you have this?" Sarah's small unsure voice floated down to them barely more than a whisper.

"Its The TARDIS Sarah I have lots of things for lots of reasons" The Doctor said annoyed at Sarah's stupitity she knew that already.

"Yea but that doesn't explain why you have this" Sarah walked down beside them staring at a piece of white paper in her hand.

Her eyes were wide with confussion not as wide as Clara's went but not far off it. She handed the bit of paper to The Doctor. It was a photo of a woman he knew from his 8th regeneration, She had long wavy dark hair that went down to her bum, large blue eyes and full red lips. His 8th regeneration had been insanly attracted to her. The Doctor remembered how her curvy body felt under his past self's hands.

"Thats my mum" Sarah's voice broke slightly

"No it's not" The Doctor shook his head his voice higher than normal

"It's from when she worked for the goverment. She had a picture simaler in her room only there was a man in it with longish hair and a cravat" Sarah said struggling to remember

The Doctor looked from Sarah to the photo, They did look alike. He didnt know how he hadn't noticed it before. Memories of Mary McDoyle came flooding back to him. He met her while helping UNIT out with a small alien invasion in mid nineties. She was beautiful and clever and funny, He'd only spent a week with her but oh what a week it was he'd showed her The TARDIS and they'd made love in the open doorway as they flew through the time vortex. At the end of the week he left to go fight in the time war he'd promised to go back to her but never did.

"Is it the same woman?" Clara asked dragging The Doctor out of the dark pathway his thoughts were about to take

"Could be" The Doctor shrugged.

Then it all clicked into place. Mary worked for UNIT the UNIT stuffed with alien technology. Alien technology plus human stupidity its unbeatable. The 1%!. River said who and what. The TARDIS was attatched to Sarah like a mother. River was overly friendly with Sarah. The Doctor launched himself towards the console. All sorts of feeling flooding him confussion understanding anger happiness and desperation.

"Doctor what's going on?" Clara asked alarmed

"You!" He shouted pointing at Sarah it came out harsher than he intented and Sarah jumped looking scared "Stand here quick" The Doctor pointed to the floor beside him.

"Doctor what are you doing?" Clara shouted this time slamming her hands down on the console and leaning over it too look at The Doctors face.

"Scanning" The Doctor said simply.

"Scanning what?" Clara asked sounding desprate now. The Doctors only answer was an uncharacteristicly huge smile

The TARDIS was humming loudly as if she was excited. Sarah was stood beside him now looking confussed and slightly scared. Things usually got bad when The Doctor got emotional and he was looking a whole host of different emotions and Sarah didn't like it. A green light scanned from The Doctor's feet all the way to the top of his head before doing the same to Sarah.

"Biological DNA match confirmed. Paternal match... Positive" a female voice sounded from the screen infront of them.

"What. What does that mean" Sarah asked her voice shakey

"You're my daughter" The Doctor explained a small smile on his face.

"Excuse me. What?" Clara asked in disbelief

The Doctor pressed a few buttons and a picture of his 8th incarnation appeared on the screen.

"That's the man in the picture of your mums" The Doctor stated

"Y-Yea" Sarah responded her eyes hadn't left the screen and she looked alittle pale

"That's me in my 8th body. I met your mum when she worked for UNIT" The Doctor said nodding towards the screen

"But Sarah's human. isn't she?" Clara asked unsure.

Before The Doctor could respond Sarah fell to the floor screaming in agony her body convulsing

"What's happening?" Clara shouted in panic as she bent down to check on Sarah

"She's changing! We need to get to UNIT now!" The Doctor shouted back perfectly calm and setting The TARDIS into flight.
