CHAPTER 11

Seventh day of October. Day 1751 since the infection. Tegan Smith video log.

Lot of things have happened since the last time I recorded something here. New results have fallen. New specimens have been delivered. Even the hierarchy here has changed. I was a simple neurologist working for the great Maxence Spitz. This man is certainly a clever one. The cleverest of us all. I admire him; this is no secret to anyone, and working for him is a great honour. He treats me better than my old boss who was constantly belittling me and giving me tasks that didn't fit my abilities. Maxence let all my competences come out and exploited them the right way. His team is family to me and for someone who has grown up in an orphanage, that's something really important. I fit in this team, in this family, and they accept me for who I am and never make any mean remarks but actually explain what I've done wrong and show me how to fix it. I'm evolving in the right way this time. Every step I take is a new progress to me. Well, until Maxence went out for this mission.

I can honestly say that I hate the person who forced him out of his lab to go on the field. Catching a living specimen… It really was a stupid idea and a suicide mission. Only someone who didn't know about the reality of things outside could ask for such a stupid thing. It could only go wrong and it did. It was a real disaster. Some would say that it could have gone worse than it did. Only three men are down on the ten that were on this mission. One death, two infections. To me, it's a huge mistake to have sent them outside. Event if it was for a good cause, finding that damn cure, what we've lost isn't worth what we've gained. Our leader, my mentor, Maxence Spitz, has been infected when a nightwalker bit his neck. Xavier died protecting him from a possible slaughter and Allegro… Allegro kept Maxence safe until they could come back here. Maxence has turned into a complete nightwalker. He has come back here in a crate and was transferred in a cage immediately after they arrived here. Allegro is infected though he has no symptom. He was transferred anyway.

This obviously caused a huge mess in the hierarchy of our lab. We didn't have a boss anymore and the chief of our security teams is down too. New leaders needed to be named. Maxence had picked his favourites before leaving. Wise man. That's what I was thinking before I heard that I was now the leader of this team. Me, out of other people like Jack or Rose or Clara who deserved it more than me. Jack thinks that's because Maxence had seen something special in me. I'm wondering what it is honestly. I'm perfectly aware that I wasn't born a leader. I have the feeling that all my decisions are wrong. Was it a good idea to name Rory captain of all the security members? To have created that small cell working on Maxence? I've always been afraid of failing and right now, it's worse than ever despite the support I have from the very same team I've created. Especially from Jack who is a better ally than I thought he would be with his changing mind and his extravagant personality. He clearly knows his limits.

Rose worries me a lot too. We can't deny that it's her husband we're working on and it's seriously affecting her. We can't pretend that we don't see that she's not okay but she's kinda avoiding us so we won't force her to talk about what is weighting her heart and ours. We can't say that she doesn't do her job properly because it would be wrong. She's doing it more than right but she's taking inconsiderate risks by always be around Maxence. We still don't know how the virus gets from one person to another. If there's any problem, we would lose another brilliant mind and this team would be lost. However, this proximity they share is also a good point for us. She was first to notice that Maxence wasn't like any of the other nightwalkers, that he still had that part of humanity inside him. After further researches, Jack, Clara and I had come to the same conclusions. His DNA isn't totally corrupted and his blood and brain are partly working like they used to before the infection but his primary needs like water and food and sleep are off. That's what is making the nightwalkers aggressive and stupid.

We had to sedate him to get clear scans of his brain. He was refusing to stay still even after we've tied him down which made him rather furious. He already was when we've put him in the crate to carry him to the scan room. It hadn't been easy to catch him at all. He absolutely refused to come to us and had put as much distance as he could between him and us. He was avoiding us and when he felt cornered, he attacked. No one was harmed thankfully but we all were the witness of his intelligence. He ran straight to the palm reader. We haven't thought of forbidding him the access because we never thought he would actually do something so clever in his condition. Zach was quick to lock the airlock thankfully. That's a mistake we won't do ever again. It could have had such disastrous consequences for us all. We were luck enough on that one. We may not have a second chance if we mess up once again.

The sedative has had some interesting effects on his system. The humanity, what's left of it in him, is increased by the sleep. I've noticed it on the scans before and after the sedative. Rose had noticed that his eyes were slightly losing their black colour. The original colour of his irises was showing up. It disappeared with the last effects of the sedative. I've seen that Rose recorded another entry in her video logs, an entry where she gives details about his vital signs while he was sedated. They weren't normal but they weren't very abnormal either. They were in-between but it's a good sign for us. If we can 'force' his brain to feel the primary needs again, it could maybe reverse the process. It's not gonna be an easy task obviously but we already fixed his sight today. We have forgotten that Maxence was short-sighted with all of that. It didn't get better with the noctiagus but we gave him his glasses back and he looked better with them on. As if it had really changed something for him. We'll see the results in the near future.

I won't post this video on the public interface. It's more like an entry to my diary than an actual scientific report and it's better if no one sees it. I just needed to vent and it's done. End of the talk.

Tegan sniffled and wiped his nose with a paper tissue. He was being emotional again. He hated being like this. He took a deep breath in to try and release the tension from his shoulders. This promotion was hard to live and he was restlessly wondering if he was doing things right. It even kept him from sleeping. He was exhausted but just couldn't sleep. Not like Maxence who didn't feel the need to sleep. Tegan rubbed his face and met the stubble growing there. He hadn't shaved in days. They would all look wild if they didn't have time to take care of themselves. They probably wouldn't take the risk to shave Maxence. It would be giving him a weapon and it was dangerous to let something like a blade in his hands. Who knew what he would do with it? He was compelled to live with the growing beard on his face.

Tegan smiled sadly at the memory coming up to his mind. He was remembering the first time he had met Maxence. A day he would never forget. Back then, he was working in the NINE, one of the most famous labs of this country. NINE stood for National Institute of Neurological Engineering. At first sight, you would say he was on his field but if you looked closer, he clearly wasn't. His job there was only to keep his eyes on a screen and read lines of codes that weren't related to neurology. He had learnt how to decipher those data and to report whenever there was a problem in a technology he could only dream of using.

– Flashback –

Tegan was leaning in his chair, bored. He hadn't taken his eyes off of this screen in hours and there was nothing to report. This machine was working too well and it was burning his eyes to stare at the screen. He was having a hell of a headache once again. He had developed a tendency to violent migraines with this job. Even the meds he was taking couldn't relieve him and he didn't have the time to go and see a doctor. If he was absent for one second, they would fire him and he couldn't lose this job even if they were treating him miserably and barely paying him. That's the only thing he had at the moment and he didn't want to lose the small flat he was renting.

He rubbed his eyes and face as if it was gonna take his pain away. He hadn't shaved in days and the hairs growing there were itching. It was the least of his troubles though. He had the feeling that someone was hammering nails right behind his eyes. How could he work correctly in such a condition? He glanced at the screen. Still no sign of a flaw in the codes. He grabbed the scientific magazine he had bought in the morning. With all of that, he hadn't had the time to even open it. He had bought it because there was an article about Maxence Spitz' new project and works. The man himself had a picture on the front. In a small frame on the side, but still.

He admired this man and what he had done so far in scientific community. He was the greatest genius of this era. His colleagues here were mocking him, pretending that he wanted to be in a relationship with Maxence. It wasn't like he would refuse if the man wanted to have a one-night affair but he knew that Maxence Spitz was straight and married with another genius of this planet. Anyway, for Tegan, Maxence would be the scientist who would change the whole world with his discoveries. He was so clever he could find a cure to the biggest and most lethal diseases this planet could count. And there were a lot of them.

He put the magazine aside when he heard a knock on the door. It was rare to have someone knocking on his door. Not because he didn't have many visits – the developers were maybe afraid that he would screw their precious codes up and were always checking – but because no one thought necessary to show him a bit of respect by knocking on his door while he was working. Sometimes, he was locking it just to be in peace and he was being yelled at for this but they weren't sacking him for this. It wasn't big enough of a mistake. Today was one of these days. He sighed and got up. He unlocked the door, opened it… and stumbled backward at the person standing before him. He thankfully managed to grab the side of the door to keep on his feet but the man before him was divided between a worried and a bemused face.

"Are you alright?"

Tegan would have recognised that northern accent anywhere. He had gone to lots of conferences just to hear the theories of its owner. Maxence Spitz. Doctor Maxence Spitz was standing before him.

"Y-Yeah," stuttered Tegan. "You surprised me. Didn't expect you to be behind that door. Not many people knock around here."

"They should. Surprising a scientist while they're working could be dangerous."

"I'm afraid I'm not doing anything that dangerous."

"That's why I'm here. Can I come in?"

"Sure."

Tegan let go of the door and gestured to Maxence to come in. He was slightly shorter than Tegan thought he was but he was compensating with his presence. This man certainly knew how to impose himself. Tegan offered him his desk chair and sat on an old wobbly stool. He was nervous and he had to stick his hand between his knees so it wouldn't show. Maxence took his time to glance around him and his eyes fell on the magazine. He grabbed it and smiled.

"They begged me for this interview," he chuckled, opening the magazine to the page he was. "I honestly hate being the centre of attention. My wife thought it would be a good idea though. Like wearing this awful tie."

He played with it for a moment. He hated ties as much as he hated suits but Rose had forced him to wear one for this interview. He wasn't very comfortable in those clothes and it was clear. Tegan moved nervously on his stool. He was wearing the same tie. He cleared his throat. Maxence looked up at him and his face showed how embarrassed he was.

"Sorry. I didn't mean that it was awful. It's just that I'm not a suit and tie man. I'd rather wear a t-shirt and jeans. But it's not professional."

Tegan was surprised to see that the man he admired was someone so normal. Someone like him in the end. It was quite funny to witness but if he didn't get back to work, he would be in troubles.

"Don't you mind me interrupting you but… you said you were here for professional reasons… implying me?"

"Oh… yes! Yes, absolutely! Like I've said to these reporters, I'm working on a new project, which is still confidential, and I'm looking for my own team members. It appears that you're the best neurologist in the area. I've come here to poach you. Your director doesn't know the chance he has to have someone as talented as you since he's not using your potential the right way."

Maxence pointed to the lines of codes still flashing up on the computer screen. Not a job for a neurologist.

"You can have me. Right now. I take the job."

Working for him would be a big honour and Tegan would make sure to never disappoint him if he was taken in his team. Maxence chuckled at Tegan's eagerness and serious. He definitely was motivated for the job.

"Your contract is ready on my desk. I've just come here to let your director know he was gonna lose an important member of his lab and to meet you personally."

Tegan was so surprised to be hired so easily without any job interview or tests that he would have fallen if he wasn't sat. Maxence stood up and stretched his body. He gave a smile to Tegan and held a hand out to him. The neurologist shook it absently. He was too shocked by the situation.

"I'll see you tomorrow morning. 8, in my office. No obligation to wear a suit or to be clean-shaved, unless you like it."

Tegan acquiesced. It was like a dream come true. He had a new job. A new job with a boss treating him decently. A new job where he would do what he loved. And all of this was thanks to Maxence Spitz. God must have heard his prayers.

Camden McCarson was an old grumpy Scottish man. It was the description he was making of himself of course. He would rather think that he had attack eyebrows because the world was doing everything to make him cross. It wouldn't come to his mind that he was just a bitter paranoid man who had suffered from so many ordeals in his life that he preferred being as pessimistic as possible and making mean comments whenever people were getting on his nerves. He was always on the move, always travelling as far from home as he could. To the question what was he looking for, he replied that he would know when he would have found it. So far, he couldn't say he had found anything that was fitting his expectations. He still couldn't put words on what he was looking for but the adventures his job was creating was enough to make him forget.

He was making money by finding stuff and people that seemed to have disappeared from Earth. Once, he was working on a rather tricky case that had led him in the middle of Chiswick – something about a sat nav who had been stolen from the army, a sat nav full of secret information. That was the day he met Donna Noble. This red-haired woman had burst out in his life like a fury because he supposedly had collided with her car. It had appeared – after she was done yelling at him and hitting him – that they were working on the same case. Him, because he had been hired for it. Her, because she was bored in her life and had heard of this very important sat nav lost in nature. The medias had heard the rumours of this disappearance and it was all over the television and newspapers. Everyone was looking for a person to blame and the medias were worsening the situation.

Of course Camden's bosses had already tried to reach him but he hadn't taken the calls. He wasn't the one who had leaked the information and he certainly wasn't gonna let anyone yell at him for something he hadn't done. He would rather be sacked than being accused of something. His bosses knew better than to sack him though. He was their best element and he could be insubordinate and impolite and grumpy as much as he wanted because they wouldn't take the risk of losing someone like him. So, when he had brought Donna to them asking for her to be his sidekick – 'I'm no one sidekick!' had she barked at him – because she was really good – not better than him but close enough – they had hesitated only the time to hear their final report on the matter they had worked on together. She had been hired based on those results.

Camden wasn't an easy man to work with but he had quickly learnt that Donna was no woman to be led around by the nose. She would rather have a go at him than accept his orders. They were always bickering on how to do some things but their work was done right and that was what mattered the most in the end. Plus, Donna knew she was indispensable to the man. She had taken him out of the loneliness he was burying himself into and she was often checking on him and taking him out of his office whenever he was locking himself in there for days just looking for a new interesting case, waiting for his boss to call him for a new inquiry. He reminded her a lot of Sherlock Holmes when he was like this. But mister Holmes was far from being as good and clever and arrogant as Camden McCarson could be.

His office wasn't what Donna had expected either. She was imagining him more in an old room with ancient furniture, libraries full of books and secrets, and maybe some painting portraits of past family members on the wall. His name seemed to have some nobility in it after all, but if it had any, Camden McCarson didn't care at all about it. He was living his own life with his own rules and no one could change that. His office was surprisingly modern, all in stainless steel and blue and orange neon lights. He indeed had libraries full of ancient books and it was fitting strangely well in the middle of this office. There were two tables with four computers on them and flat screens hung on the wall just above. The computers were analysing the deep and dark web and the screens were silently displaying the news from all around the world. The best way to find good news to use.

To complete it all, there was a huge desk in the bottom of the room. It was facing the door and turning its back to the large window although the owner of the place loved turning around to catch the spectacle of the sky when the sun was either rising or going down the horizon. He could also spend nights looking at the stars through the lens of the telescope set by the window. Camden McCarson certainly was a man full of knowledges and a great collector of weird objects that didn't make sense to the beginner she was. She had learnt that asking questions could sometimes give answers. As long as she wasn't asking about the woman that was on the picture he kept on his desk. He never replied to this question but she had often seen him lost in his thoughts while he had his eyes on this photography.

When she stepped in his office that day, he was leaning in his chair, his feet crossed on his desk, his hands folded behind his head. A smile grew on the corner of his lips when he saw her. It was night outside but thankfully, he had offered her a room in the gigantic manor he was living in so she hadn't had to go through the dangerous streets to meet him when he had called her at over 4am. Which was making rather moody to be honest. She hated being woken up by the mad man.

"Don't you ever sleep?" she grumbled.

She had taken the time to pull on some clothes before coming. He would never seen her in her pyjamas. He was already being an arse with her normal clothes so if she did show herself to him in pyjamas, he would either choose to ignore them or make a comment that would infuriate her. Better not take that chance.

"Barely."

"Yeah, I've noticed that."

To be honest, she had never seen him sleep. Whenever she was seeing him, he was up to something and he never seemed tired. But once again, it was a question he never really answered to whenever she dared asking him why he would stay up all the time.

"What is so urgent that requires me to be up in the middle of the night?"

"We have a new case."

"You've finally found something worth your talent?"

"Someone sent me an email from London."

"There are survivors somewhere in the capital."

"Seems like it. Listen to this." He brought his laptop closer to him and started reading the mail he had left opened. "Mister and Miss McCarson…"

"Hm," disapproved Donna.

"I know, as if we could ever be married or even related."

"Oi, watch it old man!"

Camden preferred ignoring the remark and not raising it. Their clients were always thinking that they were related in some way because of their 'similar personalities'. They must be really blind to think such a thing of them. They were barely friends so to think they were relatives or married…

"My name is Tegan Smith and I'm working at the London Centre of Researches for Contagious Diseases. As you might know, there is a virus spreading in the world and all the labs around the world have been requisitioned to find a cure against it. I can't say more through this mail as our mission has to remain a secret to the people who aren't working on this case. However, my colleague, the doctor Jack Harkness, has found something that needs to be examined by a professional detective. He highly recommended your services. Would you agree to a meeting with the doctor Jack Harkness and myself in the days to come in our lab? Please, let me know your answer quickly. Patiently waiting for your reply. T.S."

"This guy sounds like a newbie promoted to the head of his team by these dark times."

"What surprises me the most is that I know Jack very well and I also know he's been working for one of the most brilliant minds this world can count."

"And that mind isn't Tegan Smith."

"Oh, no. That's why I wondered what happened to the real boss of this place."

"So, you wanna go just to see what he's up to?"

Camden put his computer aside and uncrossed his legs. He put them down and bent forward in his chair, leaning his head on one hand. He gave Donna another smirk. This was one of the reasons, yes. Maxence Spitz was a very interesting man and Camden couldn't resist fighting another brilliant mind. He liked challenges and this looked like one.

"We don't have much work lately, don't you agree?"

"I'm not surprised at all since the world is coming to an end. Do you ever watch your own screens?"

She pointed her thumb on the screens displaying the news from all around the world. Different channels but the news was the same: the virus was spreading, there were less and less survivors, less and less hope to find a cure. Some were even saying that the end of the world had come like the Mayas predicted millions of years ago. How many times the end of the world had been announced over the decades? It would be astonishing to have one being true in the end.

"So, are we taking this case?"

"We are."

"I'm preparing our luggage."

Donna quickly left the room. She wasn't reassured by the fact they would have to travel through Scotland and England to reach that lab requiring their help but she guessed that security means would be established for them to travel safely. Especially since the situation had gone so critical in the last few days.

To the doctor Tegan Smith's attention:

My associate, Donna Noble, and myself have examined your request and concluded that we were accepting the case you're offering us. We can be there tomorrow. We leave to you all the organisation of the security means to guarantee our safety until we reach your lab.

Cordially,

McCarson & associates.

The mail was sent and now, Camden was too thrilled to even find sleep. This mission was a real opportunity for Donna and himself. They better not screw it all up. So, while Donna was taking care of their luggage – more hers than his since she wasn't his dogsbody – he made sure they would have a flight for London with his personal jet. No need to take risks and travel in public planes. They had to get to London quickly and discreetly and he hoped that Tegan Smith would make sure their security was guaranteed or it would cost him a lot…
