"Right then, Doctor who I'm about to be. Tag, you're it."

"With these words, the change began, as it had so many times before. How many times had it been? 13? 12? Probably a lot more, given what he had learned in the Matrix recently. The fact the Doctor was referring to himself as a man was either a habit, or a sign that things would be getting back to something more familiar.

The Doctor's mind drifted back to the beginning (or what his memories told him was the beginning), back when he was that crotchety white-haired old man. At the time, he was travelling with his granddaughter, or at least he thought she was his granddaughter. At some point, she adopted the Earth name "Susan", and it had stuck with him, mostly because her Gallifreyan name was difficult to pronounce. But that was besides the point. At the time, they had landed on Earth - this was before the junkyard that locked the TARDIS into being a police box - to find themselves surrounded by men in armour. "Pardon me, my dear fellow.", he had asked one of them.

"Why, you are on the outskirts of Rome.", the warrior had answered him. "At the dawn of our new emperor, Caesar Tiberius."

"Ah.", he had soon realised, before turning back to his granddaughter. "Then it must be the year 14 anno domini. A fascinating period of transition."

But his granddaughter didn't share his sentiments. "Oh Grandfather, let's get out of here, please."

But the old man had been insistent. "And miss the chance to behold such an important event? Certainly not."

And so the pair had requested the aid of the legionary in travelling to the coliseum so they could behold the event. They arrived in tie, to witness Tiberius's investiture, and joined in the chants of "Hail Caesar! Long may he reign!"

Time passed since then. Not just for the Emperor, but for the Doctor and his granddaughter, who took the name Susan and settled down on a war-torn Earth with a young man. But as for the old man, he met his end at an arctic base during Earth's first documented battle with the Cybermen. But it was far from being all over. The old man became renewed for the first time, regenerating into a younger body. And so, he continued on with his adventures.

By this point, he was travelling with Jamie and Victoria, a time-displaced pair from the 18th and 19th Centuries respectively. They had just departed from an Earth covered in ice - and Martian Ice Warriors - to end up on another planetoid. "Where are we?", Victoria asked.

The Doctor checked the TARDIS' instrumentation. "Hmm, that's odd. There's something strange with this planetary map. It just says '14'."

"Aye, your machine's broken as the rest of the TARDIS.", Jamie commented snidely. "I bet we'll go out there and fall out into space."

"Oh really?", the Doctor asked as he went over to the door switch. "We'll see, shall we?"

But Victoria was quick to run over and try to stop him. "Wait! What if Jamie's right, and there is nothing out there?"

"Don't worry, Victoria.", the Doctor assured her. "If there's any trouble breathing, then the TARDIS will keep us safe." He then clicked the switch, opening the doors to reveal a wasteland full of smoke. "Well, everything seems to be safe. We can venture out of there with no trouble."

But no sooner had the Doctor stepped out, was he accosted by a familiar mechanical creature - a Cyberman. "Stay where you are!", its mechanical voice droned as it grabbed onto the Doctor. "Any attempt at resistance will result in you being destroyed."

As the Doctor recoiled in terror, Jamie came bounding out of the TARDIS. "Creig a Teurre!", he cried out as he ran forward, throwing a knife into the metal giant's chest. As the Cyberman recoiled from this attack, Jamie grabbed onto his friend. "Doctor, come on."

The two hurried back into the TARDIS and took off, little knowing that the Cyberman had been intact enough to record everything and transmit that data back to their home planet Telos. "All data has been recorded."

Time passed for the Doctor. Soon after, he found himself caught by his people, the Time Lords, and sent to Earth in a new body that he wasn't allowed to choose. During that time, he had the secrets of the TARDIS taken from him. But he managed to find a second home in the form of employment at UNIT, under Brigadier Lethbridge-Stewart. Despite resenting his exile, the Doctor had come to enjoy his time on Earth, to the point he had stuck around after his exile was lifted.

It was the morning after Jo Grant had chosen to stay behind in the Welsh countryside to marry a scientist she had fallen in love with. The UNIT personnel were still partying to celebrate the engagement, with the exception of Captain Yates, who had gone on leave at a resort owned by Sir Charles Grover and the Doctor himself. He had sequestered himself in his work back at London, taking his mind off the sadness he was feeling.

He had just connected one of the cathodes to his new computer when the tea lady came in. "Not today, thank you.", the Doctor said dismissively.

"Oh, that's a shame sir.", the poor old woman commented, as she went and started pouring anyway. "I made the effort to brew a pot to help you feel better about your assistant leaving."

The Doctor immediately realised something off. So he decided to test things. "On second thoughts, maybe I'll take a cuppa." He then allowed the woman to pour two cups full of the brown liquid. "I think I'll take this one."

But as the Doctor reached out to take his choice of cup, the tea lady grabbed his arm. "No, I must insist you take this one." When she said this, it was with a masculine voice. A rather familiar masculine voice.

"Ah-ha!", the Doctor announced as he leapt up and pulled on "the lady's" face. "You may disguise your features, but you've never been able to disguise your intent." As the Doctor suspected, beneath the mask was his best enemy… the Master.

"My dear Doctor.", the Master chuckled. "And here I thought your current isolation was more than an ample opportunity to claim your remaining regenerations."

The Doctor smiled at this. "You mean you went through all twelve so quickly? My dear fellow, I'm sorry to hear that. But really, you don't have anyone to blame for that."

"That's true.", the Master nodded, as he picked up the cup he was insisting on before and held it up to the Doctor's mouth. "Which is why I've simply decided that since you're currently the least secure Time Lord in the area, I'll simply take all of you-."

But he was interrupted by a shot to the back, sending him reeling. The Doctor turned towards the source of the shot. "My dear Brigadier.", he commented. "For once, I'm grateful for your habit of appearing in the nick of time."

"Well it's just as well I had to report in about this whole Global Chemicals business.", the Brigadier nodded. "Otherwise we wouldn't have finally taken care of the Master."

The Master took off one of his gloves, which was glowing. "Looks like I've still got a bit left.", he commented. "Another time, gentlemen." He turned and set off running down the corridors of UNIT HQ."

The Brigadier moved to stop him, but the sound of a TARDIS materialising filled the air. "It's no use, Brigadier.", the Doctor cautioned his friend. "He could be anywhere in time and space. Or anyone for that matter. Even a familiar face."

Familiar faces. As the Doctor regenerated again, he remembered that he hadn't spent a lot of time outside of infrequent summons back to UNIT among familiar faces. But in this new face, he had gained the companionship of a robotic dog from the 51st Century. K9. After the dog left with his friend Leela to stay behind on his own home planet, he used the technical knowledge he had gained from studying the internals of K9 to construct an almost identical copy.

"How are you feeling, K9?", the Doctor asked to test the robot's receptors. "All systems functioning normally?"

"Affirmative, Mistress.", K9 responded, to which the Doctor responded with a shocked look on his face. This wasn't as easy as it seemed. So the Doctor went back to retiring him, a process that went on for hours, until he was interrupted by a beep on the console.

"Now who could that be?", the Doctor asked as he went over and pressed a button, activating the scanner to reveal a fleet of Kroton ships. "Attention, you have entered the Kroton Empire's sector of space. You will vacate the area, or be annihilated."

The Doctor scowled. The Krotons were possibly one of the dullest species in the universe. He couldn't charm them like he normally would his other adversaries. So he went over to K9. "KO, could you persuade our friends out there to let us go in peace? Do a little bluffing?"

"Affirmative, Master.", K9 nodded.

"Good, good.", the Doctor nodded as he plugged K9 into the communications array.

"This is your last warning!", the Kroton radio transmission blared again. "Vacate the Kroton Empire or you will be destroyed!"

At the Doctor's cue, K9 began transmitting. "Fools! Entering your system was childs' play for a powerful race such as we. We have access to vast amounts of acid, which can break through your tellurium bodies with ease. So if you do not allow us passage, we will unleash our load."

Fortunately, the Krotons were too small-minded to question this story and accepted it as fact. "Message received. Now departing." Witty hat said, the Kroton fleet turned and began flying away.

"Well thank heaven for that.", the Doctor said, breaking a sigh of relief. "If that hadn't work, I don't know what I would've done."

Now when you're a Time Lord, especially one who makes a habit of ending evil throughout the universe, you're bound to pick up some enemies. And some of these enemies have the resources to hire assassins versed in temporal obliteration to deal with obstructive elements. Like Nina the Cleaner, the 14th most deadly assassin in the universe. She'd been hired to both deal with a little man in a ridiculous jumper carrying an umbrella, usually accompanied by a girl covered in far too many patches to be inconspicuous.

She'd tracked his space time location to that of the Beatles' 14th performance at the Cavern Club, due to a massive amount of non-terrestrial signals coming from that date. So her secondary mission was to deal with them. The first she saw was a large mouthed man about to devour a man in a frock coat and his brown haired companion. "I really hate amateurs.", Nina hissed as she brought out a gun resembling a vacuum cleaner and fired on the creature, miniaturising him and shrinking it down.

"That's odd.", the version of the Doctor that the woman had inadvertently saved, in his pleasant, open-faced fifth incarnation commented.

His current companion - well, one of them. His other was currently recovering in the TARDIS from possession by the Mara - asked him "What is it, Doctor?"

"Oh, it's probably nothing.", the Doctor decided. "But why do I feel like my future's catching up with me?"

A few feet across town, closer to the club, Nina came across another obviously out of place figure - in this case, a woman with purple skin - who was seemingly tailing a man who looked like he was auditioning for the circus, accompanied by a female who obviously wasn't indigenous to the area, going by her accent. Nina took out a switchblade disguised as a mop and used it to stab the alien in the back and drag it off. The alien let out a high pitched wail, which the woman - one Peri Brown - heard. "Doctor, what was that scream?"

"Oh, it's probably just some overeager fangirls.", her Doctor insisted. "Ringo always did think they got closer than was comfortable."

"No, it sounded different.", Peri insisted. "Almost like someone in pain."

"Oh, if you're nervous, we could always go elsewhere.", the Doctor insisted. "I've already been to this performance anyway. Perhaps we could try one of David's shows in a few years. We'll have more room to breathe there."

Nearby, Nina the Cleaner was sighing. "God, amateurs make me annoyed. And I still haven't found the Doctor, or his assistant."

"Then allow us to save you the trouble." Nina turned around, and both of her targets were standing right there, smiling at her. "We'll come to you.", the Doctor said.

Nina pulled out a compact laser pistol from her handbag. "You've made a big mistake coming here, Doctor. I'm about to claim my reward."

"From who, though?", Ace asked. "Because while you were dealing with two other aliens your bosses' rivals hired to take the Professor out, their bosses took out yours in a gang war."

"Such a shame.", the Doctor lamented. "They could've won if they had a good assassin amongst their ranks."

It was then that Nina realised the truth. "You mean, you antagonised the Syndicate…"

"So that you, their best agent, would be sent here.", the Doctor concluded that sentence for her. "And also deal with some other assassins that were being a bother." Nina then pulled out her time hopper, trying to activate it, only to find no result. "I wouldn't bother."

"Yeah.", Ace nodded. "After the coppers found your lot we're using those things, they made them illegal and had them deactivated."

The Doctor and Ace then walked back to the TARDIS, leaving the stunned Nina behind. "Honestly, assassins these days.", the Doctor commented. "No dedication."

Back in the present, the regeneration's most important stage - the change of face - had begun. The Doctor noted that his body had indeed become a man once more. And it seemed that as a result of using Gallifreyan fabrics to make a short notice replacement for her old outfit, they'd changed into a suit and trench coat for his new body. A fairly familiar style too. Familiar like…

"I k ow these teeth.", was the new Doctor's first words, as he blurted out what he was thinking. He started feeling his face, and sure enough, it was identical to one of his previous faces, albeit slightly older. "What? What? WHAT!", he then asked, getting slightly back into the swing of having this face again.

And speaking of old faces, he thought back to his Eighth incarnation, a man who led seemingly led multiple different lives at the same time. Right now, he was travelling alone, and had been called back to be present at a historic peace conference: of all things, a non-aggression pact between the Daleks and the Time Lords. He was now sat on the side with Davros. "Any funny business from you, and I'm sure the Time Lords won't hesitate to wipe your creations from existence."

"Oh, Doctor. You always think the worst of any situations.", Davros assured him. "My Daleks and I are not fools. We are aware that the outcome of this day will cement our future."

The three delegates from Gallifrey stepped up to examine the document. "Bupay the authority vested in my, by the High Council of Time Lords," the lead delegate stated. "I add their seal to this treaty with the Daleks of Skaro, in the spirit of friendship and goodwill. So that our two races may…"

"Exterminate!" The Daleks fired their lasers, taking out all three delegates in seconds. One of them then wheeled over to one of the freshly deceased corpses. "Harvesting brainwaves."

The Doctor burst out of his chair at this. "What's the meaning of this, Davros?"

Davros merely laughed at this. "You really thought my Daleks would make peace with your people? After all their attempts to ensure their extinction and I went to the trouble of giving them the desire for supremacy your people hold claim to? I requested this conference so that we could acquire information on your people and their defences. As I promised you once before Doctor, The Daleks will sweep away Agllifrey and become the Lords of Time. Your people will be unable to mount a defence."

"You seem to have forgotten something.", the Doctor pointed out as he leapt over the pews and pointed to the TARDIS in the corner. "I can still warn them." He then set off running.

"Stop him!", Davros commanded as his Daleks pointed and fired their lasers. But the Doctor was fast enough to make it inside the TARDIS and depart before the worst of their shots could hit him. "No matter. The Time Lords will not be able to mount more than a pitiful defence against my Daleks. They will prove once and for all the superior beings in the universe! And then, they shall become the new Time Lords, crushing all lesser beings with their unimaginable power!"

And so, a war began, between the two titans of the universe, in which time itself was the battlefield. The Doctor stayed out of the War at first, but soon realised that he had to regenerate into a Warrior to save what was left of the universe. Years passed, and Davros perished at the Gates of Elysium, devoured by the Nightmare Child he created. But the war continued, as the Time Lords revived their own greatest hero, Rassilon, to lead them, leading to the conflict being prolonged as forbidden weapons from the Omega Arsenal were used.

But the man formerly known as the Doctor - which everyone still referred to his as, for lack of anything better - continued to fight, and 14 years into the conflict saw the battle of Skull Moon. So named due to being the former home of the Skeletoid hive mind. Now in the 14th year of the Time War, the Daleks were after the technology that had previously fought them off and nearly pushed the Cybermen into an alliance with humanity. The Time Lords were also after this tech.

The man formerly known as the Doctor led a platoon of troops into the remains of the Skeletoid's central intelligence chamber. "What ended the Skeletoid menace?", one of them thought to ask. "I mean, one minute they're a threat to three of the greatest empires at once, the next they just get nuked."

"Oh, just a few good men doing their work to save the universe.", their Commander answered her. "There's a legend saying that one of them was from Gallifrey, but that's not very likely, is it? Most who would've left Gallifrey to assist in such a conquest were renegades and scoundrels in gaudy outfits."

"You mean like you, sir?", another soldier asked. The Commander didn't acknowledge this with an answer, instead urging the soldiers to follow him into the control room.

But when they entered, they were met with Dalek duplicates, in full uniform. "Covering fire, now!", the commander insisted as he made a dash for the console, while the soldiers engaged the duplicates in battle. The commander placed a device on the console where the Skeletoid weapons files were stored. "Now then, time to prime this device.", he pressed the button on the device, before taking out a recall device he had borrowed from the High Council's chambers. "Well, job done. Time I was out of here."

A pair of soldiers heard the sound of a TARDIS and saw a familiar blue box appear around the Doctor. "Wait, sir.", one of the pair insisted as they both walked over to where the Doctor was standing, as the TARDIS fully materialised, and then dematerialised as an explosion on the console took out all the other computers, and eventually the entire compound and everyone inside, regardless of sides.

A small number of casualties, compared to the rest of the War. Only two or three soldiers on either side walked away from that battle. Even fewer of those squads survived the Time War, even as the Doctor took the Moment and ended the War. He regenerated again, now once more the Doctor, went out into the universe, believing himself to have killed both Daleks and Time Lords alike. But soon, he started taking on companions again, in the form of Rose Tyler. They went on the trip of a lifetime across the universe, visiting all sorts of special planets. "So, what's this place then?", Rose asked as she stepped out into a rocky terrain with thunderstorms in the skies. "'Cause this ain't exactly the most friendly looking place."

"You wanted to know a bit about my home.", the Doctor answered as he led her to a cavern. "This place is Crafe Tec Heydra. The one record of the Last Great Time War in the whole universe." Sure enough, within the cavern were several crude carvings, depicting a race of men battling a race of metal. "Of course, this had to be heavily sanitised so people could consume it. Trying to put the entire war into someone's brain could drive them mad. Of course, living through it isn't much better. Sometimes, I have to forget parts of it."

Then Rose took note of a piece of text, which looked like English. It read 'You are not alone'. "What does that mean?", she asked.

"Dunno.", the Doctor shrugged. "Maybe it's just saying that I've got you. Maybe it's telling me something I won't figure out for a while." He then turned and walked back to the TARDIS. "Maybe sometimes, these things are better left alone."

And so, the Doctor had continued on, taking on the face he had taken right now for the first time. Rose stayed with him until she ended up separated by the walls between worlds. So the Doctor tried to continue on, taking on new friends such as Martha Jones and Donna Noble. And things seemed to be moving on for him. But soon, on a visit to the planet Shan Shen with Donna, she told him of an encounter with a mysterious woman in a parallel world built around her who told her two words: 'Bad Wolf'.

"Doctor, what is it?", Donna asked as the TARDIS's interior glowed red, as the Cloister Bell sounded. "What's 'Bad Wolf'?"

The Doctor was quick to answer. "It's the end of the universe." He ran over to the controls, operating them to set the TARDIS in flight. "No, no, no, no, no!"

"Doctor, what's wrong?", Donna questioned.

"It's just… vanishing.", the Doctor said in response. "Over half of the history of the universe, all the dates, the places, the event… they're vanishing. As if they've never existed."

"Is that Bad Wolf?", was the next thing to come out of Donna's mouth.

"No, that's just a warning.", the Doctor clarified. "From Rose Tyler. I just need to find a point before this paradox, one that still exists in the vortex." He dialled input commands into the console, causing the lighting to slowly return to normal. "Come on, we just need to get there." The console burst into flames, with pieces of it flying everywhere. "We just need to get to before the 27th June 2009. Not sure why that date's where everything's been erased afterwards, but whatever." The Doctor and Donna were sent stumbling towards the door, as the fire on the console put itself out and the text above the door returned to normal, with the familiar wheezing, groaning sound that indicated landing. "Alright, now let's see if everything's fine.", the Doctor said to Donna as the two walked out of the TARDIS.

Poor Donna Noble, the Doctor thought back in the present as he stepped away from the cliff. Unfortunately, she'd undergone a metacrisis, becoming part-Time Lord. The human brain would burn under the strain of all that extra knowledge. So he had to block her memories of him and all their adventures, ensuring she'd live, but at a price. While the Doctor went on alone for a while, eventually ending that life with no-one else. His next incarnation on the other hand, went some ways to starting a family, even going as far to get married.

He'd been on Trenzalore for 14 months by that point. Standing guard on the planet to prevent the aliens gathered in orbit from destroying the planet and its people, but currently unable to leave, due to the TARDIS taking its time to get back to the planet from Earth. But this just made the Doctor more willing to keep fighting for the planet, in the hope he could avert his impending death.

The planet was supposed to be prevented from invaders by a shield that would destroy any technology more advanced than 21st Century Earth. The Doctor had managed to use the TARDIS to smuggle the Sonic and his current robotic assistant Handles through, but others were even craftier. As he remembered when a meteorite came crashing through the atmosphere, which opened on impact to reveal a familiar blonde-haired woman. "Hello, Sweetie.", River Song smiled.

"River!", the Doctor blurted out. "What are you doing inside a meteorite?"

"Well I did not want to get on the bad side of the Papal Mainframe.", she answered. "Especially after last time. Now what's this I hear about you staying here?"

"Well, it's partly because I've lost me motor.", the Doctor answered. "Not to mention the tiny detail of a new Time War that lot up there think will happen if the Time Lords return from within a crack in the church after I say my real name. Blimey, that sounds super complicated."

"Oh.", Rive nodded understandingly. "So that would explain the technology barrier that those Monoids just snuck through."

Sure enough, the Doctor turned around to see a group of Monoids using their heat prods to shoot humans. "You foolish creatures!", their leader announced via his speech synthesiser. "You could have surrendered the Doctor and spared yourself all this trouble. But now we shall be forced to take your settlement for our own kind."

"Funny thing.", the Doctor said as he walked over to the Monoids. "You're fairly low on my list of enemies, so I wouldn't have thought to keep an eye out for you.", he continued as he pulled out his Sonic. "But since you're so brazenly rampaging here, like bulls in a china shop, which would have to be a very large china shop, with quite a lot of cheaply made wares for the bull to do any damage. In fact, forget the bull and the china shop."

"What are you babbling about?", the Monoid growled.

"Oh, when he starts talking, you'd better run.", River pointed out. "Because the Doctor talking and waving his Scredriver can only mean one thing."

The Monoid was now confused. "And what is that?"

"Christmas is defended.", the Doctor answered, as a beam sent from the Papal Mainframe came down, vaporising the entire force of Monoids.

"The Papal Mainframe apologises for your deaths. The relevant afterlives have been noted.", an announcement blared out.

"And I think that's my cue to depart.", River said as she pulled out and dialled her vortex manipulator. "Sure I can't offer you a lift back to the TARDIS?"

"She's just being a bit slow.", the Doctor assured her. "But it'll show up eventually. Thanks anyway."

"Right.", River nodded. "See you later. Or earlier." She then warped into the Time Vortex, leaving the Doctor alone with his thoughts.

But it all worked out. After 900 years, the Time Lords decided to give the Doctor a new regeneration cycle, which allowed him to survive and defeat the Daleks, the one invading force that still threatened the people of Trenzalore. The first new incarnation of this cycle, an older man, proved a much gruffer character than before. To the point his friend Clara Oswald had found his new attitude upsetting enough to walk out on him. Until one day, she called him on his phone.

"Clara, this is a surprise.", the Doctor stated into the phone. "Especially after how things ended last time."

"Oh, it wasn't that bad.", Clara tried assuring him. "We're still on speaking terms, right?"

"Your exact words were 'Get back in your lonely bloody TARDIS and you don't come back. You go a long way away'.", the Doctor answered. "That seemed like a pretty final goodbye."

"Let's not let a few harsh words be the end of it.", Clara chuckled nervously. "Maybe we could go for one last hurrah."

The Doctor seemed intrigued by this. "Well, do you have anywhere in mind? The Rexel Planetary Configuration with its 14 stars? The Globe Theatre before the original burned down? Maybe we could take your suggestion of forming a band with Jane Austin and Buddy Holly?"

"Yeah, let's not do anything too out there.", Clara insisted. "Something familiar, but with a few alien elements. Surely there was an alien on… I don't know, the Orient Express, or something."

The Doctor was shocked by this. "If it's the Orient Express you want, then I can give you that. And I guarantee you some thrills." He hung up the phone, before redialling another number. One who'd given him some spam calls for a few centuries. "Yes, hello. Is that offer of free tickets still open? I think I've accidentally booked a date…"

As it happened, the Doctor and Clara were able to fix their relationship and continued travelling together for a while. But all good things must come to an end. Eventually, the Twelfth Doctor met his end with some grace, after fighting it off for perhaps too long. Regenerating into a woman for the first time. Or what he thought was the first time. The Doctor soon discovered that she was originally a life-form from an unknown species that could change their appearance 12 times. The original inhabitants of Gallifrey had took her in at the edge of known space, at a portal to the next universe, and hijacked the child's abilities for their own. And the Doctor couldn't confront her people - or who she thought were her people - because the Master had found the information out first, and laid waste to Gallifrey. Shortly afterwards, following 70 years in a space prison, she was now once more travelling the universe, with police officer Yasmin Khan.

"Doctor?", Yasmin - or as the Doctor had taken to calling her, Yaz - asked one day. "What exactly did you see on Gallifrey that day? You p've been really quiet on it?"

The Doctor wasn't sure she wanted to answer this. It was a fairly personal matter, of course. But she felt she should explain a version of it to her friend. "I saw something from my past. Someone messed with my memories of who I am. And I don't have any idea of where to find the person responsible. All I have to go on is the word 'Division'."

"Then, there must be a database of information that might provide you with a key to finding out more.", Yas pointed out. "Surely the Time Lords had an internet of some kind?"

This gave the Doctor an idea. "The Matrix had the information hidden deep down. So it might also be in…" she dashed over to the console and started operating the controls. "The Record of Rassilon, programmed into every Type 40 TARDIS, containing long forgotten knowledge from ancient Gallifrey. That might include…" She finished typing, causing a holographic list to be displayed. "A complete list of the members of Division. Now, I just need to cross reference them with individuals alive in the relative present day and…"

The console started beeping. "What's that mean?", Yas asked. "Do we have a match?"

"Oh we most certainly do.", the Doctor said ecstatically. But as she said this, the TARDIS started shuddering, with crystals growing out of the walls. "Oh no, I should've realised. They put a time virus on that information. Any attempt to access it will corrupt the TARDIS's interior dimensions, making them unsafe."

"Can we fix it?", Yas asked.

"We can.", the Doctor nodded, as she continued to operate the controls. "But right now, we've got a Lupari to catch and ask some questions."

And back in the relative present, with the Doctor having finished flashing his entire life before his eyes, he set off back into he TARDIS, running up to the console. "All right then, universe - what have you got for me today?" He then heard the sound of an alert. "What's the whauw-ing?", he asked, before inspecting the controls to find the right button to respond. "Huh. I used to know here systems like the back of my hand -." But then he looked at his hand and spotted the flaw in his logic. "Only it's someone else's hand now. My old hand." Then the TARDIS set itself in flight. "Do what? Dematerialising? But I didn't touch anything!" And so once more, the Doctor and TARDIS set off through time and space, with no idea of where they'd end up.
