"This is Doctor Martha Jones, the time is 09.27 on the 3rd of March 2009 and I'm about to begin the autopsy on subject 76584. I am being assisted by junior medical technician Private Gerald Sutherland. The subject of our autopsy was discovered during a routine salvage mission on 1st March 2009. At the time of the discovery Subject 76584 was already deceased. He… she… or possibly it, any sexual orientation is yet to be determined, was located at the rear of an unidentified vessel which crashed in the foothills of the Andes.

"The deceased organism was located in what has been described as a holding pen. I have photographs of the scene where and I believe the subject to be a prisoner or possibly livestock being transported on the vessel. It is unclear if the subject is a member of a species that would be considered sentient and intelligent. At this time there are no indications of the origins of the spacecraft. It is not of a design known to UNIT and we have yet been able to locate any pilots or crew, hence the urgency of this autopsy. My brief is to record and report any pertinent information which could assist in identifying any threat this incursion into Earth territories may bring to the peoples, or the resources, of our planet.

"The immediate custody and transfer of the subject was personally undertaken by Brigadier Alistair Stewart and I have been led to believe he insisted this lab took responsibility for determining the nature of the organism, the cause of its death, and whether it should be considered a threat. My involvement in this case was requested due to my experience in the field; however, I've not seen anything like this organism before, either in the extensive UNIT libraries or in my travels – documented or otherwise.

"It appears to be entirely covered in a reflective substance; it was originally described as some kind of armoured skin-suit, however, my observations lead me to believe this organism is in fact protected by some kind of integrated exoskeleton. It is bipedal and conforms to the symmetry of a humanoid type organism; it measures… 227 cm from foot to toe; that is just over 7 foot? Visual observation of the hip joints would suggest this organism is as comfortable walking on all fours as it would be walking upright. There are no visible features on the subject's head; nothing that could be described as eyes or a nose or a mouth or ears. Without further examination I can identify no sensory organs. Initial pre-autopsy attempts to X-ray the organism have resulted in failure as the outer scaled layer is impervious to our scans.

"The subject's whole body is covered in thick scales ranging from 5cm to 15cm in diameter, all fitting together in a hexagonal pattern. They appear to be a uniform mid grey colour, however, as was discovered during transport, when exposed to ultra violet light there is a shift and the scales become iridescent, like oil on water and the grey illuminates to turquoise. I will take a sample for analysis once the visual observations are completed.

"There are some marks and abrasions on the subject's body which likely indicate injury was received during the crash. One wound appears especially serious and is located at what I believe is the rear of the subject's head. The absence of facial features or obvious gender specific organs seems to make the idea of front and back arbitrary. As the creature is lying on the table at the present time the wound is located at the rear, however, this may in fact be due to the orientation of the subject rather than an accurate biological description. The wound to the organism's head is significant and pending further investigation a potential cause of death.

"Subject 76584 is intriguing and unlike any life form I have previously encountered. From visual observations I am unable to determine how this organism respires, feeds, reproduces, interprets the local environment, or communicates with other members of its species if it is indeed capable of such communication. There are four distinct appendages on each of the two upper limbs. The entire body is covered in the hexagonal scales save for the lower abdominal area where a gelatinous compound appears to have adhered to a cellular tissue. The cells within this gelatinous compound are uniform and roughly spherical. It is unclear whether this is the result of some kind of injury or is a natural state for the organism. Again, I will take samples once visual examination of the subject is complete.

"I am going to begin by further examining the wound to the subject's head…" Martha took up a pair of tweezers from the tray of tools at her side. She was just about to attempt to clear some tissue from the wound when there was a knock on the Perspex screen separating the self-contained, sterile autopsy lab from the rest of the science and medical block of the UNIT centre of operations.

"Go and see what they want, Gerald, would you, please?" Martha didn't want to delay the autopsy any further. The subject had already been transported half way round the globe. It was refrigerated but would not keep forever. With an unknown alien spacecraft crashed in the Andes she needed to find out what she could and relay that information back to the Peruvian office. UNIT were pushing for answers because of a potential alien threat. Martha accepted that was true, but after such a crash she was worried there may be injured aliens requiring medical assistance.

Gerald, her assistant went to the metal grille positioned in the side of the Perspex screen. He pressed the intercom button and spoke to the UNIT soldier on the other side who'd requested their attention, but could not enter the autopsy lab without the protective clothing and face shields Martha and Gerald were wearing while dealing with the quarantined alien corpse.

"Doctor Jones?" Gerald addressed her formally when there were soldiers around. A previous medical assistant had been hauled in front of a disciplinary board after being heard to call her Martha whilst working on a traumatic case. She'd been disgusted by the military inability to accept first name terms, but it was not the time to be pushing. "Colonel Mace is requesting your attendance at an incident in Warehouse 7."

"What, right this minute?" Martha removed her face mask and went over to the window to talk to the UNIT soldier directly. She recognised him as one of the last intake having conducted his medical assessments at the start and again at the end of his training period. He seemed very young. Many of the new intakes did as UNIT had been required to reduce their minimum recruitment age having lost so many soldiers during the Dalek invasion and Earth's trip to the Medusa Cascade. "Private Coates isn't it?"

"Yes Ma'am." Came his tinny response through the intercom.

"I am sure you can see I'm rather busy. If Colonel Mace has requested a medical officer attend Warehouse 7 then Doctor Wilson is the first response medic today."

"Yes Ma'am, understood, Colonel Mace specifically requested your attendance. He anticipated your reticence, Ma'am, and said to inform you of a Code 9."

"A Code 9?" Martha knew what that meant. "In Warehouse 7?"

"Yes Ma'am."

"There is a Code 9 actually in Warehouse 7?" She wanted to make sure she was entirely clear of the circumstances of her call to the warehouse. The young soldier nodded his affirmation. "Then please can you get on your radio and advise Colonel Mace that I request the Code 9 be escorted to the Autopsy Lab?" Martha turned and addressed Gerald without pressing the intercom. "He may be able to provide valuable insight into Subject 76584." Martha breathed a sigh of relief. She worried the organism on her autopsy table was so far removed from anything she'd encountered previously that she'd not be able to provide the Peruvian Field Office with the information they needed.

The soldier was on the radio through to Colonel Mace's team, which Martha assumed were over in Warehouse 7. The intercom wasn't pressed on either side so she couldn't hear what was being said and Private Coates had turned slightly, so she wasn't able to decipher anything from reading his lips. Private Coates eventually returned to talk through the grille into the autopsy lab.

"Colonel Mace advised that the Code 9 does not appear to be a straightforward."

"What does that mean?" Martha worried. "Let's just cut to the chase. We all know what a Code 9 is, so, is the Doctor here or not?"

"That is unknown, Ma'am."

"But there is a Code 9 in Warehouse 7?"

"Yes Ma'am. I was stationed in Warehouse 6 at the time of the incident."

"Incident?" Martha felt her stomach bubble with worry. Something wasn't right. Colonel Mace was responsible for pulling her off routine duties to complete the autopsy with strict instruction to all parties that she not be reassigned for the duration of the procedure, now he was pulling her off. "A full report on all you know, please, Private."

"Yes, Ma'am, at approximately 08.55 hours I was stationed at Warehouse 6 awaiting orders following morning parade. I was there with seven other members of my unit. We heard what sounded like strange engines straining in and out, and then there a crashing sound. On investigation we discovered a Police Box located in Warehouse 7. We believe, form our case studies, it to be the TARDIS and that it has crash landed."

"The TARDIS crashed?"

"There was a lot of noise Ma'am and a large hole in the warehouse roof and part of the rear wall has been demolished. The rest of my unit have been charged in making the area safe. On discovering the TARDIS we immediately contacted Sergeant Harcourt who liaised with Colonel Mace. Both attended and Colonel Mace has attempted to gain access to the TARDIS or to make contact with anyone inside but has been unable to do so. It was after failing to make contact that Colonel Mace ordered me to bring you directly to Warehouse 7."

"The TARDIS crashed through the roof and there is no sign of any occupants?"

"That is correct, Ma'am."

Martha started to take her protective clothing off as she moved toward the airlock separating the autopsy lab from the main changing areas. "Gerry?" No one would ever dare to question her professionalism by using first names with her staff. "Can you relocate Subject 76584 back into the chiller-drawer. If you could download my dictation to the main drive and encrypt it with level two medical coding I will pick it up from there later. Then, if I have not already returned, catch up with me at Warehouse 7 and just in case, bring the full field kit over as well."

"Yes, Doctor Jones," Gerald acknowledged and got to work as Martha entered the air lock and secured it behind her. She shimmied out of the overalls she'd been wearing for the autopsy, not bothering to redo the laces in her boots. She tucked them into her thick black boot socks. Once she got in the jeep she could sort them out.

"Why do you think he is here, Ma'am?" Private Coates escorted Martha to an open top jeep waiting to drive her across the extensive site to the warehouses.

"I don't know." Martha paused as she clambered up into the front seat of the jeep beside Private Coates who would drive her. "But, there are two possibilities that come to mind. Knowing the Doctor, as I do, had he been seeking company he would likely call into a freelance journalist called Sarah Jane Smith, had he been seeking assistance he would likely call into Captain Jack Harkness of Torchwood. I can think of two reasons why he may have come to UNIT. The first is that he is aware UNIT have possession of Subject 76584 and either has information or feels he needs to take jurisdiction, or, secondly, that he is not visiting UNIT but has come to find me, and that concerns me most as his medical doctor."

"Do you think he may be sick?"

"The TARDIS has crashed through the roof and he's not come out. Yes, it concerns me he may be injured or sick." Martha was trying to think of other reasons why he may have turned up. She knew he'd not come to her for a social visit. Not initially. If he was there because of Subject 76584 why hadn't he come out of the TARDIS? Why hadn't he landed closer to the Autopsy Lab instead of across the other side of the base in Warehouse 7? His driving wasn't always the best, but for him to have crashed through the roof? Martha reached across the dashboard and flicked a switch that lit up blue lights in the grille to warn pedestrians and other vehicles they were exceeding the campus 10 mile an hour speed limit. "Put your foot down, Private."

"Yes Ma'am." Private Coates accelerated and Martha held onto the roll bar above the seats. It wasn't far to Warehouse 7, but he could tell the medical director was anxious. "You're friends with him, aren't you, Doctor Jones?"

"I like to think so," Martha confirmed. "I travelled with him for some time. He better bloody be alright, or I'll regenerate him."

They arrived at Warehouse 7 and Private Coates skidded to a stop outside the main entrance. Martha leapt out and ran into the warehouse having thought through as many potential scenarios as she could think of. All realistic ones led her to believe the Doctor needed her medical assistance.

The TARDIS wasn't facing the main doors of the warehouse but was at an angle. Colonel Mace was waiting to greet her, but he had two full units of soldiers surrounding the police box with their weapons drawn. There was no wonder the Doctor wasn't coming out with 24 guns pointed at him. It further highlighted her fears and proved he'd not come to UNIT unless called or there was an urgent need.

"Colonel Mace, instruct these men to lower their weapons." Martha was angered by the sight. She knew the Doctor would be and she knew Colonel Mace knew the Doctor would be. Whatever was going on they didn't need to point their guns at him.

"Doctor Jones." Colonel Mace saluted her on her arrival and she returned the gesture formally. "Once established it is there is no threat I will give that order, but since there has been no contact from within the TARDIS the nature of its business here remains unknown. I request your advice on how to proceed? We're unable to gain access."

"Stand down and put your guns away," Martha repeated. "I've got a key."

Martha felt quite sick. She knew she shouldn't and that she should be ready to jump into action. She was often called in to incidents, even as the Medical Director for UNIT she maintained her hands on doctoring as a regular member of the first response team, covering shifts in their triage centre, or taking in rounds and dealing directly with patients in the medical wings.

There was nothing on the outside of the TARDIS that would indicate she had been through any serious scrapes, but there was definitely a hole in the warehouse ceiling and Private Coates had not been exaggerating when he'd said part of the rear bricked wall had been brought down. It was a pile of rubble. The position of the TARDIS made it clear she had caused the damage. She could see lights within the TARDIS which was positive; she'd be more worried if she was dark.

Martha went right up to the door of the TARDIS as all but the two soldiers on point put their guns down. She accepted that was as far as UNIT were going to go until it was clear there was no threat. She knocked on the door. "Doctor?" She waited a moment but there was no response. "Doctor, it's Martha, are you in there?" She waited again and received nothing. "I've got my key, Doctor, so, I'm coming in."

Her TARDIS key had been kept on her personal bunch. Not because she ever thought she'd need it for the TARDIS, but because it had been a part of her perception filter as she travelled the Earth. She kept it near her to remind her how lucky they all were. Now she slid it into the lock on the TARDIS door hoping the Doctor hadn't suddenly got security conscious about all the human stragglers there were with keys to his ship and home. He hadn't and the door unlocked. Martha cautiously pushed it open.

It felt significantly cooler in the TARDIS than it normally would, so much so that her breath condensed into a billowing cloud. In contrast to the cold air she could smell burning. Not the sometimes pleasant smell of wood smoke, but a sharp acrid smell of singed electronics and melted plastic. It wasn't overpowering, it was faint, but it was pungent enough to be immediately noticeable.

"No one else is to follow me in here, except Private Sutherland when he arrives," Martha ordered the soldiers standing guard around the TARDIS. "Doctor? Are you in here?" Martha stepped into the TARDIS. She pulled the door to behind her so there were no prying eyes. A section of the console was damaged and hanging off. There were wires and some scorch marks that suggested it was the source of the smell. Although there was light in the TARDIS it was coming from the emergency lighting rather than the main rotor which suggested she had powered down to prevent further risk of fire.

It was fairly clear to see what had broken the console. There was a large heavy-duty metal ladder tipped up and lying over the console and wedged against the upper platform running round the edge of the flight deck. She looked up at the ceiling. Way up above the time rotor, close to 25 feet, above her head two access panels hung open with different wires hanging out.

"Martha?" The Doctor was on the floor, slumped against the bottom of one of the TARDIS corals. His voice sounded weak and distant.

"Oh, Doctor?" Martha didn't have to ask what he had been up to and if he was alright. She could see he wasn't. He was incredibly pale in contrast to crimson blood coating half of his face. It had dripped and run in streaks into his shirt. It was smeared over his cheek where he'd wiped it with his hand but he'd done nothing else to deal with the wound or stem the bleeding.

Martha went around to the other side of the console first and ducked down to check underneath it. She was relieved to find the first aid kit she had made him update and replenish while she had travelled with him was still hooked under the lip. She hoped he'd not used it and left it empty like the original one which had been rusted into place.

Martha clipped the first aid kit open as she went to him and knelt down beside him. "Hello." She looked him over. It looked like he'd been wearing his coat at some point, but had got his arms out of it. He was still sitting on it and it was ruffled up behind him a bit between him and the coral, and resting over him so he'd not made the effort to take it right off, just shrugged it off his shoulders as if he was too hot despite Martha's breath condensing on the air.

"Hi."

"Am I right to assume you started up there?" Martha pointed toward the open ceiling panels. She wanted him to answer the question even though it was fairly obvious. She wanted to make sure he remembered and that his speech was clear. He seemed quiet and subdued, but she could clearly see the wound on his head was significant. It was curved and full thickness. There was a lot of blood. It coated the hair on the left side of his head and was down his face and into his shirt. Under the sticky red mess she could see the left side of his face looked swollen around his eye and cheek. His eye was almost swollen shut and she suspected that under the blood he was rapidly developing a spectacular shiner.

"The ladder tipped up."

"You've taken a nasty knock to your head, Doctor." Martha got some dressings out ready. "Did you knock yourself out?"

"No."

"Do you remember everything leading up to and since the ladder tipping?"

"Yeah, I do."

"That is a good start." Martha smiled sympathetically as she snapped a pair of gloves on from out the kit on her belt. She carefully pulled some of his hair to the side. "It looks like the wound in your head has mostly stopped bleeding on its own. So, I'm going to cover it over. We can clean it and have a good poke around and make sure there isn't anything untoward going on when we get you over to the medical bay. You're going to need some stitches I'm afraid."

"I thought as much."

"Have you any symptoms of concussion?" Martha knew the Doctor knew what they were. She asked him the broad question and then she'd break it down and confirm each indicator one at a time to double check with him. If he did have a concussion there was a chance he would be shaken up and confused and not know what the symptoms were, so she wasn't just going to let him make the decision as to whether he was concussed or not. As she suspected he denied it. She was suspicious as to why he remained on the floor half out of and half tucked into his coat if he didn't.

"I don't have a concussion."

"Okay, good, so no visual disturbances?"

"None."

Martha got her penlight from her kit and clicked it on. "Look straight ahead for me, Doctor," Martha instructed. She checked his pupil response. It was clear, quick, and even. She clicked the light off. "Look at the end of the pen for me?" she instructed. "Follow it with your eyes." She moved it from left to right and then up and down. His left eye was swollen to the point of it being almost closed, but what she could see looked fine. "Have you got any nausea?"

"No."

"Okay, good. I am going to keep an eye on you to make sure nothing develops. I want you to tell me if anything starts to develop. Let me just cover cut over for you. You've hit your face as well, haven't you?"

"I hit my head and face on the side of the console."

"The TARDIS has taken quite a whack from the ladder?"

"Yeah, she struggled to get into the air. She's damaged too." The Doctor sounded concerned so Martha elected not to tell him that she'd crashed through a warehouse roof. He didn't bring it up so she didn't know if he knew how badly she'd landed. It didn't seem to have been as damaging to her as the way the Doctor had landed from the ladder.

"Let's cover the cut on your head and then clean some of the blood up and have a look at what is going on underneath," Martha suggested. "I have a fine young medical assistance going to catch me up in a few minutes and then we'll get you over to the medical unit." She fastened a dressing over the wound on his head as she talked to him. He didn't even flinch. It worried her because his demeanour and manner indicated he was in a lot of pain. She had seen him hurt and this was him being hurt, but if it had just been a cut to his head and a black eye she didn't see why he'd come to her. He'd be highly animated and complaining when it was something minor. That he was quiet and subdued suggested to her it was serious, and that told her it was not his head.

"What else do we have to deal with?" Martha didn't ask him if he was hurt anywhere else. She knew he was. She just didn't want to go prodding and poking him to find out. He'd fallen about twenty five feet, Time Lord or not, that was a fair distance. "You're going to have to tell me, aren't you?"

"Yeah."

"So, come on, unless you want me to do top to tail poking? I know it must be bad for you to come here rather than deal with it yourself." She was terrified he wasn't telling her because he'd hurt his back and was too scared to admit it. Come to think of it he wasn't sitting in a particularly comfortable looking position.

"Where else are you injured?" Martha knelt beside him. The metal grate was harsh, but she knew the Doctor was in far greater discomfort than her criss-crossed knees. It seemed for a moment that the Doctor was just going to break and lose all his battles against the pain he was enduring as if not acknowledging whatever it was and not talking about it made it hurt less. She knew mind over matter was a powerful aspect of the Doctor's existence so it was possibly very close to the truth and telling her would make it hurt more. "Doctor?"

"My right leg…" the Doctor grimaced as he continued, "…it's broken."

"Okay." Martha tried not to audibly gulp.

"It's bad…"

"Let's have a look," Martha offered positively.

"I don't really want to look."

"Okay, I need to though. So you can look away for a moment, but it may not be as bad as you fear." The way he was sitting he was twisted onto his left hip and that made more sense if his right leg was causing him pain. His coat was tucked over the top of both his legs so she'd not immediately seen. She'd been drawn to the blood on his head and face as the immediate concern and had not taken in what looked increasingly like an unusual position for him to be sitting in. She went to pull the coat back, but the Doctor gasped.

"You can't touch it!" He sounded panicked as his voice hitched up a couple of notches.

"I'm just going to look for now, but, Doctor? If you have broken your leg…?"

"I have!"

"Then," Martha continued calmly in order to try to bring the Doctor's level of distress back down. "I am fairly sure you've not come here just to show me have you?" Martha instinctively took his hand. His grip was tight and she could feel the slightest tremble that was otherwise imperceptible. "I'm going to have to touch you at some point, Doctor, but I'm not going to do anything other than look just now."

"It hurts."

"When Gerald gets here he'll have my kit and I'll be able to give you some proper pain relief before we think about getting you over to the other side."

"Not morphine." The Doctor keened as his resolve broke slightly.

"No, I know. I always keep a good stock of Time Lord friendly drugs and I have some in my kit just in case. I never know if I'm going to need them." Martha carried on holding his hand and she used her other hand to carefully ease his coat tail out of his lap and reveal his right leg. "Okay." Martha swallowed. "I'm going to need them."
