The Secrets of Sarah Smith

Sarah was laying in a hospital bed next door to the medical bay laboratory she had been hooked up to different machines two of which where trying to keep track of her heart rate but it was weak and her left heart was dangerously slow about half its usual speed. Her temperature was extremely high for a human never mind a Timelord and nothing The Doctor or Martha did would get it down. Her skin was as pale and white as the light bedsheets placed over her as she slept but she wasn't peaceful her high temperature was giving her vivid dreams that made her mumble and move her head around violently in distress.

On more than one occasional The Doctor had heard her mumble about Stephan and beg him to stop hurting her. It was during these moments the Doctor struggled to remain calm, every time he was reminded of his daughters past he felt rage building up inside him and wanted nothing more than to go back and stop it from ever happening but he knew he couldn't it would create to much of a paradox. Instead he just had to mop her brow with a damp cloth to try and combat her temperature and fantasise about punching the guy in the face another thing he knew he could never do but still it helped the anger slightly.

They had been working on trying to find the cure for a day and a half now and were getting no were, the fact that they now had a sick Sarah to deal with at the same time didn't help, strangely though she wasn't showing any of the symptoms of the virus apart from the temperature which confused and fascinated the Doctor. He was studying Sarah's latest test results when he noticed something really unexpected.

"Clara pass me Sarah's blood results from yesterday" The Doctor asked gruffly

"You could try saying please" Clara moaned getting fed up of being his run around for the past day and a half.

"Fine, please, now give me" He snapped holding his hand out impatiently.

Clara handed him the folder with much more force than necessary but the Doctor never said anything just tore the folder open and to a human seemingly skimmed through them but for a Timelord he was taking in every letter of the page. He couldn't believe what he saw, it was completely and utterly impossible. There was no way the results were right, they couldn't be but he checked and double checked both sets of results before he allowed himself to believe it.

"Doctor what is it? What's wrong?" Clara asked sensing his agitation.

"Nothing. Nothing is wrong" The Doctor answered looking up at Clara with a large smile "Where's Martha?" He asked

"getting some sleep its 3am Doctor" Clara answered sounding slightly concerned that he didn't know this.

"It is? Why aren't you asleep then? Don't you pudding brains require a lot of sleep?" The Doctor asked slightly miffed Martha wasn't here to explain everything to.

"I didn't want you sitting on your own" Clara answered simply with a small smile that turned into a yawn.

"I'll be fine, you should go to sleep, don't want you getting too tired now do we?" The Doctor mumbled his head back in the results

"Oh look at you being all caring, thought that was my job" Clara joked

"It is, I just don't want to be dealing with your bad mood in the morning and you look awful with black circles under your eyes" The Doctor grumbled waving a head absent-mindedly at Clara.

"Thanks for that" Clara said her voice tripping with sarcasm and rolling her eyes

"Your welcome, Now got to bed" The Doctor dismissed her not even noticing the sarcasm.

A few hours later Martha arrived back at the laboratory/ medical bay looking only slightly less tired than the day before, The Doctor was just about to comment on it when she spoke first.

"Clara said you found something out last night?" Martha asked setting a coffee cup down beside him. "Yes there's 7 sugars in it" she added dismissively when he sniffed the coffee before taking a tentative sip.

"Sarah's blood results. the infection levels are dropping" The Doctor answered her, pointing to the folder.

"What?! how?" Martha demands snatching the folder of the desk and flicking through it.

"She's clever, the virus only effects dual hearted species so her body's shutting down one of her hearts to trick the virus" The Doctor explained taking a larger mouthful of coffee.

"Would that work? would it get rid of it?" Martha asked looking up from the folder

"No idea probably not, the virus will still be her system but it just won't attack" The Doctor said standing up and walking over to his chalk board full of gallifreyan text.

He looked over his work from the previous night and added a few more symbols here and there before running his chalk covered hands through his grey curls in frustration. Martha had returned to Sarah's room to check on her. The Doctor paced around the room trying to kick start his brain into thinking. He discovered yesterday that they were dealing with the strain that disabled regeneration but he hadn't told Martha that yet. The Doctor was too busy frantically scribbling what really was just a load of nonsense on the board to make it look like he was making progress that he didn't notice the door between the laboratory and the medical bay open.

"Dad" Sarah's voice called out from the door way.
