Four Doctors ( comic story ) Four Doctors was a miniseries published by Titan Comics . It served as a three - way crossover between Titan ' s ongoing series " " , " " and " " , uniting the three Doctors and their companions , as well as marking the Titan Comics début of the War Doctor . It also featured a cameo by the Ninth Doctor and Rose Tyler . Plot summary . Part one . On the planet , Marinus , in the year A10 % ? , of the Last Great Time War , the War Doctor , along with a group of Voord watch as a Dalek saucer crashes into the ground . The Doctor had forced the Daleks to go through advanced evolution , reducing them all to dust . The Voord leader collapses to the ground , as his paradox shield fails . Before he dies , his armour transforms into a liquid that engulfs one of the human servants , Moktek , joining him to the Voord group mind and making him the new leader . The leader remarks on how that aspect of their species has remained the same , while so much else has changed . The Doctor agrees , noting how Marinus is now an acid desert world , very different from the lush world it had once been . The Doctor and the Voord leader head into the remains of the Dalek saucer , with the Doctor telling the leader about the weapon that the Daleks intended to use against the Voord . The weapon would ' ve erased the Voord from existence , meaning the Daleks take the Voord ' s resistance seriously . The leader asks him if the Time Lords also do so . He mentions how the Time War has changed the Voord for the better , and wants to know if the Time Lords will revert everything back to how it was , when they win the Time War . The Doctor avoids answering , bringing up how tense relations are between him and the High Council . He also mentions that he doesn ' t make grand promises about anything , unlike his former selves . But , he does agree to act as an intermediary and to try to convince the High Council , but that ' s all he can do . Even with that , the Voord leader is still worried about the future . Years later , in the TARDIS , Clara Oswald asks the Twelfth Doctor about the planet Marinus , to which he claims to have never heard of . He asks her why she asked him about it , but she lies and claims she heard the word in a dream . Later , when the Doctor is asleep , Clara enters the control room and uses the telepathic circuits to direct the TARDIS to land in Paris , 1923 . As she steps outside , she thanks the TARDIS for bringing her here . She pulls out a photograph and looks at it , the picture showing the Twelfth , Eleventh , and Tenth Doctors on it . Clara remarks on how she must prevent this event from happening , for the sake of everything . Across town , the Tenth Doctor and Gabby Gonzalez have just dealt with some Cybermen , who were trying to raid the French Gold Reserves . The two arrive at a cafe and the Doctor decides that they should have some crepes from there . He tells Gabby to go inside and order the crepes , while he disposes of the Cyberman head he is carrying . Gabby walks into the cafe and is seated at a table . She doesn ' t notice Clara sitting at the table next to hers . At this time , the Eleventh Doctor and Alice Obiefune walk up to the cafe , having just stopped some radiation monsters who were coming out of the Seine . The Doctor notices that these streets look familiar and he remembers the cafe being great . So , he tells Alice to go in and order a coffee , while he goes and gets some comics . Before Alice can be shown to her table , Clara gets up and introduces herself to Alice and Gabby . She tells them that while none of them know each other , they all know the Doctor , and she has five minutes to convince them of something , or the universe will be destroyed . The three sit at Gabby ' s table . Alice is a bit sceptical , so she asks Gabby what the name of the box is , to which she replies with the TARDIS . Alice then starts to ask Clara a question , but Clara cuts her off with the correct answer of sonic screwdriver . Gabby and Alice are now fully convinced , so Clara shows them the photo of the three Doctors . Gabby and Alice start remarking on the appearances of the three Doctors , but Clara stops them . She tells them that the Tenth Doctor will return to the cafe in five minutes . He will decide that he doesn ' t want a crepe and the two will go elsewhere . Alice won ' t witness this as she ' ll be in the bathroom . After that , the Eleventh Doctor will return , just missing his former self . He and Alice will remain in the cafe and have the coffee . Clara tells them that these events are meant to happen because this is a fixed point in time . Thanks to the timespace info on the photo , plus her knowledge of the Doctor ' s past , Clara knows that Gabby and Alice were the companions of the other two Doctors at the time the photo was taken . Clara chose to come to the cafe at this time , because she knows it was the only time she could meet up with both Gabby and Alice without any repercussions . The two understand that the situation must be serious and tell her to tell her story . The Twelfth Doctor and Clara had been visiting a nameless jungle planet . The Doctor was complaining about how the planet was nothing but jungle and ruins and proclaimed he would stand where he was , until that changed . Clara merely walked off , ignoring the Doctor ' s attitude . She stumbled upon the Museum of Terrible Fates , located inside a time shelter , which protected the contents from decay . The museum ' s computer tells her that the race that built it spent centuries scanning the timelines for turning points that would cause the end of the universe . Clara decided to look up the Doctor , knowing how he tends to be involved in situations that stop events that would cause the end . To her horror , she discovered an event with the Tenth , Eleventh , and Twelfth Doctors together on the planet Marinus . The computer told her that this event was a fatal turning point that must never happen , as all subsequent timelines of this event lead to the end of all things . Gabby asks Clara if she told her Doctor about this , but Clara simply asks both her and Alice what their Doctors would do if told . All three know their Doctors would go to Marinus . Clara then reveals that the Tenth and Eleventh Doctors will eventually meet , as she was there for that event . She recalls that the Tenth Doctor didn ' t initially recognise the Eleventh Doctor , meaning the two never met prior to that incident . She also points out that neither of them could imagine the Twelfth Doctor existing , which is how she knows the picture shouldn ' t exist . She tells the other two , that when they all leave the cafe , all three of them must make sure their Doctors never go to Marinus . To Clara ' s horror , both the Tenth and Eleventh Doctors come storming in , proclaiming that what Clara has told them is impossible . The Eleventh Doctor notices his former self , and as he doesn ' t remember this meeting , realises that this is bad for the universe . The Tenth Doctor is sceptical of the Eleventh Doctor ' s identity , having recently met an imposter . Using his sonic screwdriver , he confirms that the Eleventh Doctor is his next incarnation . Both then remark that the person they met outside is another story . That person walks in , revealing himself to be the Twelfth Doctor . He tells his former selves to shut up and then turns his attention to Clara , revealing to her that he figured out what she was up to . He tried to talk sense into the other two Doctors , but they wouldn ' t listen . So , they ' re going to have a Multi - Doctor Event , whether they like it or not . The Tenth Doctor has accepted that the Eleventh Doctor is his next and final incarnation , but doesn ' t accept that the Twelfth Doctor is a future incarnation , as it ' s not possible for him to exist . The Eleventh Doctor points out that they don ' t know what ' s going on here . Clara intervenes , telling the three Doctors to stop this and walk away . She knows this meeting didn ' t happen . Even though time can be rewritten , this moment is a fixed point in time . The Tenth and Twelfth Doctors keep arguing , with Gabby trying to convince the Tenth Doctor to leave , as she believes Clara is telling the truth . The Tenth Doctor refuses , proclaiming the Twelfth Doctor to be an abomination , a word the Daleks tend to use , as the Twelfth Doctor points out . The Twelfth Doctor turns his attention to Gabby and Alice , asking the two to tell their Doctors to listen to him . Clara has given up by this point , knowing she can ' t stop this now . The Eleventh Doctor tries to be the peacemaker between his other two selves , but the Twelfth Doctor provokes the Tenth Doctor again . In the ensuing argument , the two Doctors touch , causing a spark to shoot between them . The Eleventh Doctor confirms this to be the Blinovitch Limitation Effect , which proves the Twelfth Doctor ' s identity . A look of dread is on his face at this revelation . As he and the other two Doctors point out , they have just caused a paradox at a fixed point in time , which means only one thing . The six look up to see Reaper s appear above them . Part two . The Doctors each come up with a different plan . While Alice and Clara are annoyed at the inability for the three Doctors to be on the same page , Gabby goes with the Twelfth Doctor ' s plan of finding the oldest thing in the room , by grabbing an old mirror , which a Reaper attacks . Alice asks what the creatures are , and the three Doctors explain . Suddenly , the Reapers focus on the Eleventh Doctor , who fends them off with his comic books . The group quickly run out of the cafe , with the Reapers following , still targeting the Eleventh Doctor . He deliberately runs away from the group , with the Reapers following him . He tries running past the comic stand where he got his comics , but they ignore it , leaving him wondering why they are targeting him . The others have already worked out where the Eleventh Doctor plans on going , and reach his TARDIS before he does . The Tenth Doctor snaps his fingers to open the door , but the TARDIS is nothing more than an empty Police Box . The Doctors were already expecting this and have a solution . By triggering another Blinovitch Limitation Effect , they can use the power from that paradox to access the TARDIS interior . The Twelfth Doctor tells the Tenth Doctor to start poking him , but the Tenth Doctor doesn ' t do so . At this time , the Eleventh Doctor runs up to them , still being chased by the Reapers . One of the Reapers tries to strike him , but he and the other dodge , causing it to strike the TARDIS . Clara tells the three Doctors to hurry up . The three Doctors touch , using the energy to restore access to the TARDIS interior . The group runs inside to find themselves in the Twelfth Doctor ' s control room . The Tenth Doctor mistakenly thinks it ' s the Master ' s , but the Twelfth Doctor corrects him . The Eleventh Doctor realises that it means all three TARDISes have merged . Alice points out that the Reapers are now breaking into the TARDIS . The group runs out of the control room and down some corridors , ending up in the Eleventh Doctor ' s control room . Clara asks why having all three of their TARDISes here is a good thing . The Doctors explain that the three TARDISes provide an escape from the Reapers . Before they can explain much more , the Reapers break into the control room , forcing the group to leave . The group ends up in the Tenth Doctor ' s control room . The Twelfth Doctor starts using the controls , much to the objection of the Tenth Doctor . Gabby can see that there are hundreds of Reapers in the TARDIS , on the verge of breaking into the control room . The Eleventh Doctor slows them down , by making the air older . The Tenth Doctor thinks they should enact the plan now , as the Twelfth Doctor ' s decision to wait is putting the others in danger . The Twelfth Doctor continues to wait , stating it ' s for the greater good . The moment all the Reapers are in the control room , the Twelfth Doctor pulls a switch , causing the three TARDISes to demateralise and separate . This forces the Reapers out of their environment , leaving them with the option to either flee or die . Now back in his TARDIS , the Twelfth Doctor slumps over the console . He explains to Clara that he waited , only to ensure he got all the Reapers . Otherwise , he ' d never had put them at risk . He asks Clara if his previous selves will understand that . Clara thinks the three Doctors need a bit of time together , and Clara needs to explain what caused all this to happen . The three TARDISes land back in Paris , and the three companions let the three Doctors talk to each other for a bit . The Eleventh Doctor is glad the Twelfth Doctor exists , because it means they have a future beyond their normal regeneration cycle . The Tenth Doctor , on the other hand , is concerned . Where could they have gotten more regenerations ? He knows they couldn ' t have come from the Time Lord s . Plus , he is still worried about the eventual existence of the Valeyard . The Twelfth Doctor refuses to tell the two about their future . Clara decides now is the time to show the three Doctors the picture of them on Marinus , a planet that none of them remember . The Tenth Doctor wonders why it ' s only the three of them in the picture . He speculates it may be because the three of them are from after the Time War . The Eleventh Doctor is concerned about the fact that neither he nor the Twelfth Doctor have no recollection of these events . The Tenth Doctor states that the picture is a trap of some sort , and the three Doctors decide to head to Marinus , despite Clara ' s objections . In the Tenth Doctor ' s TARDIS , Gabby asks the Tenth Doctor why he is going to Marinus . The Tenth Doctor explains that they could go to the museum Clara found , but he doubts they ' ll learn anything new . So , that leaves him with two options . He can either spring the trap or live in fear . He doesn ' t like living in fear . The three TARDISes materialise on Marinus and the the three duos leave their respective TARDIS . The Tenth Doctor notices that there are no signs of life . He also notices that the planet seems familiar to him , an observation shared by the other Doctors . Clara asks the Tenth Doctor why he would risk the end of the universe by coming here . The Tenth Doctor says he is not . He points out the poses of himself and his other two selves in the picture . So long as they don ' t assume those poses , they are in no danger of causing the end , and can freely look around . Unknown to the group , someone else is watching them . The unknown enemy decides to interfere , to force the Doctors to take the poses in the image . The group is struck by a beam , one which the Doctors note came from outside of spacetime . The three Doctors quickly discuss plans on how to face this threat , accidentally taking the poses in the picture . The unknown enemy quickly takes the picture . The unknown enemy reveals himself to be a Voord leader and proclaims that now the Doctors are locked onto their destiny . Every step they take will lead now to the ultimate conquest of the Voord . Part three . Clara is furious , due to the three Doctors taking the poses in the photo . The conversation is cut short , due to more death rays being fired at the group , forcing them to split up . Alice ends up with the Tenth Doctor , who both notice that the trench they entered is part of a maze . The Doctor surmises that the maze is part of another trap , meaning that whoever is responsible still wants something from them . Gabby has ended up with the Twelfth Doctor , as they end up running into another area of the maze . She expresses her worry about the others , but the Doctor states that the other two Doctors are fine , because they each have " one of you lot " with them . Gabby can only wonder why this Doctor sees people the way he does . Clara is with the Eleventh Doctor , who have also ended up in the maze . The Doctor confronts Clara on the fact that she is familiar with his particular incarnation . Clara , of course , can ' t tell him anything . The Doctor can easily see that something big will happen in his future , but he is glad that there is another incarnation in his future , which takes the burden of being the final incarnation off his shoulders . He also believes that his next incarnation must be a " very cool " one , if he has someone like Clara travelling with him . The three groups reunite at the centre of the maze , where they find a weapon from the Time War : a Dalek Continuity Bomb . The three Doctors start fighting over how to disarm the bomb , which gives it the time to go off . As the group is flung through time , the Doctors explain what the bomb does . It alters an individual ' s timeline by reaching forward or backward along it and changing a single decision from whatever happened before , to whatever the bomb ' s programmer chose . The group materialises as ghost s in a different point of the Doctor ' s timeline . Specifically , they are in the Tenth Doctor ' s timeline , at the Naismith mansion . The six watch another Tenth Doctor let Wilfred Mott die in the glass chamber , stating that of the two of them , he is more important to the universe and must continue living . The Tenth Doctor is horrified at seeing this , as he would never place his life over Wilfred ' s . The Twelfth Doctor points out that , as they can see , the bomb has found at least one alternate timeline in which he did . The Tenth Doctor watches the scene continue to play out , musing on seeing what he is capable of . The group is engulfed by a flash of light , and find themselves in the future of this alternate timeline . In it , the alternate Tenth Doctor has now fully succumbed to his darker impulses and has become the Time Lord Victorious , a tyrant who rules over the universe . The Eleventh Doctor tries to reassure his former self that there are only very few timelines in which he could turn out like this , but it has no effect , as the Tenth Doctor states that very few is too many . They watch as a Raxacoricofallapatorian pulls out a gun and shoots the Time Lord Victorious , stating that the gun prevents regeneration , meaning he is now dead . The Twelfth Doctor asks what is happening as he and the Eleventh Doctor should now be dead , having died as the Tenth Doctor . The three Doctors realise that the bomb was only meant to work on one Gallifreyan , but it went off in the presence of three Doctors , meaning it ' s going to show alternate futures for each Doctor . The group find themselves in the Eleventh Doctor ' s timeline , when River Song refused to kill him at Lake Silencio , and all of history is happening at once . However , this time they glitched past the decisive moment , and are instead seeing the future of the altered decision . It doesn ' t take the group long to realise what was changed . In this timeline , the alternate Eleventh Doctor decided not to convince River to let him die . Instead , the two live together as a married couple . The Eleventh Doctor is saddened , as he can sense the universe dying in this timeline , and his alternate self is letting it happen . The Twelfth Doctor notes that if they get trapped in this timeline , then Clara ' s prophecy will come true . Alice asks why they ' re even seeing this timeline , if it contradicts the previous one they saw . The Twelfth Doctor explains that the bomb is shifting them between possible futures , which means they will shift into another one soon , which they do . The group find themselves in the Twelfth Doctor ' s timeline . They are in the TARDIS and see the alternate Twelfth Doctor . He ' s older , with his hair longer and having facial hair , and his clothes are all ragged . He ' s rambling to himself on how " she " betrayed him and how he told her to go to hell . Clara is worried that he ' s talking about her . They continue to watch the alternate Doctor ramble to himself on how he must never let anyone get close to him again . The Twelfth Doctor has had enough of this and thinks they should all leave this room until they cycle back to the Tenth Doctor ' s alternate timeline . The Tenth Doctor states that they have found the way out . He explains that the Twelfth Doctor is right , and they will soon cycle back to his timeline . The group will be stuck glitching between the three alternate timelines forever . The Eleventh Doctor realises what his former self is getting at . A Continuity Bomb timeline is usually inescapable . But , they ' re seeing their alternate futures while remaining as Time Ghosts . This means the bomb has malfunctioned and has split its energy between the three Doctors . If they commit to one of the alternate timelines , they will fully materialise in that timeline , as it will become real . As the alternate timelines of the Tenth and Eleventh Doctors lead to death and destruction , their best bet is the Twelfth Doctor ' s alternate timeline . As he has a TARDIS , he can take them all home . The Twelfth Doctor touches the shoulder of his alternate future self , and the group fully shifts into his timeline . The alternate Twelfth Doctor takes immediate notice of Clara , happy that she has come back . Clara tells him that she doesn ' t know what she ' ll do to him , but she ' s sorry . She asks him if he remembers this incident . He says he does , something about needing a lift . He starts to say that he will take Clara anywhere she wants to go , when the normal Twelfth Doctor intervenes , saying that he doesn ' t trust this alternate Doctor . The Eleventh Doctor tells the alternate Doctor that they do need a lift , so the alternate Doctor sets the controls . The TARDIS materialises in a city . The Twelfth Doctor notes that they are in a pocket universe . The alternate Twelfth Doctor states it must have been built next to the Continuity Bomb ' s timeline , as it was the only way out he could find . The Eleventh Doctor notices that the coordinates are all over the place . The Tenth Doctor states that in order for them to find their way back into regular spacetime , they will need to go outside to take some dimensional compass readings . The alternate Twelfth Doctor is against this , as he hasn ' t left the TARDIS in years . Clara manages to convince him otherwise . The group steps outside . The Tenth Doctor notes that he doesn ' t recognise the architecture of the city . The Twelfth Doctor scans the forcefield surrounding the city , and notices that it ' s holding back a sea of acid . The phrase sounds familiar to the other two Doctors , and yet isn ' t at the same time . Clara notices a welcoming committee approaching them . The alternate Twelfth Doctor takes charge , as he is the oldest one there . The normal Twelfth Doctor notices that his alternate self is unsurprised about all of this , as the creatures offer a giant capsule to the alternate Doctor . The three Doctors note that while they don ' t recognise the creatures , they feel like they should , and the capsule being offered to the alternate Doctor is a costume of some kind . They watch in horror as the costume turns into a liquid that starts merging with him . He reveals that he was responsible for all of this . The six are now the prisoners of the Voord , and the alternate Twelfth Doctor is the leader . Part four . The Twelfth Doctor is horrified at seeing what he will become . The alternate Twelfth Doctor explains that after Clara ' s betrayal , he wandered the universe alone for centuries , eventually finding his way to the Voord city , and finding companionship and healing by joining the Voord group mind . He demonstrates the effectiveness of being part of a group mind , by ordering some Voord in a small ship , to take the TARDIS away , while he is still talking to the group . The six are restrained and then led into the city . The alternate Twelfth Doctor states that he ' s not going to lock the group up and give them time to escape . After all , he knows how the minds of the three Doctors work . The Tenth Doctor starts taunting the alternate Doctor , but the alternate Doctor simply picks him up by his hair , telling him it doesn ' t matter , as they have already essentially lost , a word choice that the Eleventh Doctor notices . The alternate Doctor tells them that their destiny has been fixed for centuries , since the time the Voord were still on Marinus . Like the other species of the universe , the Voord also heard the message from the Time Lords that was sent through a crack between realities . The Voord realised that this means that the Time Lord s might return . The Voord were afraid that if that were to happen , the Time Lords could revert the universe to how it was before the Time War , causing the Voord to lose the new power they have . The Voord decided to construct a city , a city that contained all of their species . They surrounded the city with a forcefield that could last forever . They then took the weapon from the crashed Dalek saucer , and converted it into an engine that allowed them to take themselves out of reality and into their own pocket dimension , so that they would never be found by the Time Lords , should they return . Removing themselves from the universe also had the effect of erasing all memory of their species from the universe . After the alternate Twelfth Doctor and Clara parted ways , the alternate Doctor continued his search for Gallifrey , with no success . In the end , he succumbed to his despair and left the universe , ending up in the Voord ' s pocket dimension . He spent years among them , before eventually being offered leadership of the group mind . Upon doing so , gaps in his memories started filling in . He remembered the continuity bomb , and that history used to be different . He remembered that he was never supposed to find happiness with the Voord . He then gradually realised that he was to be the one responsible for the change in his history . In order for him to end up where he was now , he had to make it happen . The Voord had the ability to reach back into the main universe , anywhere in time or space . The alternate Doctor used that ability to create the museum on the jungle planet . The images that Clara had seen were all from the alternate Doctor ' s memories , including the image that led to all of it happening : the image of the three Doctors on Marinus . While the Tenth and Eleventh Doctors comment on how " timey wimey " the situation is , the normal Twelfth Doctor asks his alternate future self if he remembers his plan getting stopped by the normal Twelfth Doctor , who believes he is going to do so . The alternate Doctor admits that there are still gaps in his memory . He doesn ' t remember events as they play out after he put on the helmet in front of the group . He points out that only after he found the Voord was when his memories started coming back , and believes it was a deliberate action done by himself and that it ' s part of his plan . The Tenth Doctor tells the Eleventh Doctor to keep the alternate Doctor talking having noticed that the alternate Doctor has touched the three of them , without the Blinovitch Limitation Effect occurring . The Eleventh Doctor asks the alternate Doctor why he only went after the three of them , thinking it might have been because of the image . The alternate Doctor disagrees , thinking that his memory of the image would become whatever he decided upon . He remembered how he once searched for Gallifrey , but since the Voord don ' t want that , he has to ensure they stay lost . He targeted the three Doctors because they are the ones who might look for Gallifrey and find it , leading to time getting changed . The Tenth Doctor asks why the alternate Doctor didn ' t target the Ninth Doctor , as he is also from after the Time War . The alternate Doctor states that there was a problem involving the Ninth Doctor , and he can ' t let anything get in the way of his chosen destiny . Once setting up his timeline is done , the alternate Twelfth Doctor plans on bringing the universe under the control of the Voord . They will invade every strategic point in the universe , at every perfect moment . The Voord plan on becoming the new Time Lords , only they will take care of their domain , since everyone in the universe will be the same species . The normal Twelfth Doctor tells his alternate self to shut up . He berates his alternate self for getting a glimpse of his worst possible future and deciding to become that future . He proclaims that he will never do so . The alternate Doctor disagrees , because he will wipe the memories of the past Doctors and companions and then place them back in their timelines , unable to do anything to change the outcome . As for the Twelfth Doctor and Clara , they will be placed back on Marinus , after the bomb went off . They will retain their memories of the events , up to when the bomb went off . They ' ll assume that the bomb was faulty and that the other Doctors went back to their own times . However , the alternate Twelfth Doctor will plant mental commands into his former self ' s mind , making sure that he won ' t forgive Clara when she betrays him . He does apologise to his former self for all the suffering that he will go through . He tells them they will be taken to a device called The Conscience , where their memories will be altered . Clara tries apologising to the Twelfth Doctor , blaming herself for everything that ' s happened and going to happen . The Doctor rebukes this , telling her not to take the blame for something that is his own fault . The Tenth Doctor points out that in order for the plan to succeed , he needs to stay alive . He jumps off the walkway , hurdling towards his death , to the horror of the alternate Doctor and Gabby . The alternate Doctor orders one of the other Voord to save the Tenth Doctor , who wasn ' t really trying to kill himself , but was only acting as a distraction . While the Voord are distracted , the Eleventh and Twelfth Doctors attack their guards . Their resistance is quickly cut short , as the Voord capture the two Doctors and Clara , causing the Eleventh Doctor to drop his sonic screwdriver and his comics . Gabby dives for the screwdriver but only manages to grab the comics , before escaping with Alice . The two manage to hide from the Voord and decide to go locate the TARDIS , thinking they can use it to help them rescue the others . Meanwhile , the three Doctors and Clara have been attached to the Conscience . The Twelfth Doctor asks why they aren ' t waiting until Gabby and Alice are recaptured . The alternate Doctor tells them that the two don ' t matter , because of the point in time that the Tenth and Eleventh Doctors will be returned to . The loss of Gabby and Alice won ' t change their timelines , and their memories of the two can be erased . As such , the two companions will be executed upon being captured . The alternate Doctor activates the device , altering the memories of the four . He gloats over his victory , but notes that the two remaining companions must be eliminated , so that any other possible outcomes die with them . Gabby and Alice locate the TARDIS , and notice it ' s unguarded . The two can tell it ' s likely a trap . Since they have no way to sneak to the TARDIS , Alice decides to make a run for it . Before she can reach the TARDIS , she is shot and killed by a Voord guard . Gabby runs away , being chased by other guards . She manages to hide from them and takes stock of what she has , the only thing being the Eleventh Doctor ' s comics . She opens the packaging on the comics , but is horrified when she looks at them . Her scream alerts the Voord guards , who come running . The lead guard notes that the scream came from Gabby , who is gone now , meaning it ' s all over . One of other guards asks what they are looking at . The lead guard says that they ' re looking at her gravestone . Part five . In the cafe in Paris , 1923 , Gabby Gonzalez finishes telling her past self , Alice Obiefune , and Clara Oswald about the events she experienced and why they must try harder to avoid going to Marinus . It turns out that when Gabby opened the comics in the Voord City , she discovered a miniature Weeping Angel , that quickly grew to normal size and displaced her in time . Gabby believes it was chosen deliberately , so that she would be sent back to this moment in time , when the three companions met each other in the cafe . The three companions agree to prevent their Doctors from going to Marinus , and the future Gabby ceases to exist . Before they can do anything , the three Doctors show up . The three companions explain everything to the three Doctors . Clara apologises for everything that was going to happen , as well as her future betrayal . She points out if they avoid going to Marinus , then they ' ve already won . The Twelfth Doctor disagrees , asking her to show him the photo . He then points out the most important detail of the photo : it still exists . As such , as pointed out by the other two Doctors , the Twelfth Doctor is still doomed to become the Voord Leader . The Twelfth Doctor decides that they need to head to Marinus . Upon arriving , the three Doctors take the pose for the picture . The Voord start shooting at them and the group heads to the Continuity Bomb . However , this time , they choose the Eleventh Doctor ' s alternate timeline . Once there , the Twelfth Doctor summons the TARDIS to them , and they head back to Marinus . Since all of history is happening at once , the Dalek saucer is present on Marinus . Using the weapon on board the saucer , the group transports themselves to the Voord City . Upon their arrival , the Twelfth Doctor masquerades as his future self . He orders the Voord to take the Tenth Doctor to the Environmental Unit and the Eleventh Doctor to the Dimensional Control Unit . The Voord with the group points out that the Twelfth Doctor has lost his connection to the group mind , so he transfers his suit to the Twelfth Doctor . While the Tenth and Eleventh Doctors arrive where they need to be , the Twelfth Doctor is connected to the group mind , which he gains control of . He is then confronted by the alternate Twelfth Doctor . The alternate Doctor points out that the Twelfth Doctor ' s actions are pointless , as he can ' t avoid his destiny . The two Doctors begin to fight , with the alternate Doctor proving to be the stronger one . So , the Twelfth Doctor brings the other two Doctors and the three companions into the group mind . The Tenth Doctor tells the alternate Doctor that while linked to the group mind , they still are able to control their bodies in the real world . The Eleventh Doctor reveals that the Tenth Doctor has switched off the city ' s forcefield , while he has linked the Dalek weapon to the city ' s dimensional controls . The alternate Doctor now has a choice , to let the acid destroy the Voord , or regress them back along their timeline . The alternate Doctor is sad , as this would mean he never existed , not with his current freedom and love . Clara talks to him , apologising again for her future betrayal . She tells him that his past self would get another chance . She believes that the Twelfth Doctor ' s nature won ' t lead him to becoming the alternate Doctor , and said alternate Doctor knows this . The alternate Doctor asks Clara to never forget him , before regressing the Voord back along their timeline . The group finds themselves back on Marinus , and the Voord have been regressed to how they were before the Time War . The Tenth Doctor expresses regret at what they had to do . The Eleventh Doctor reveals that he will head out to find the Weeping Angel so he can plant it in the comics . Clara pulls out the photo to discover that the image is gone . The group heads back to Paris , to enjoy some leisure time together , before going their separate ways . Upon arriving at the cafe , they notice that the Ninth Doctor and Rose Tyler are inside , enjoying themselves . The three Doctors come to the realisation that the Voord didn ' t bring the Ninth Doctor into all this because they couldn ' t find an alternate timeline where he was anything other than fantastic . The group heads back to their TARDISes , where the Tenth and Eleventh Doctors explain that while they will forget these events , Gabby and Alice won ' t . The Twelfth Doctor expresses concern over allowing the two to remember these events , but the two past Doctors disagree with him . The Tenth Doctor is still concerned about how the Twelfth Doctor will come to exist , but both he and the Eleventh Doctor agree that the Twelfth Doctor is still the Doctor . The two past Doctors and companions depart in their TARDISes , leaving the Twelfth Doctor and Clara . Clara asks the Doctor if he is going to erase her memory , but the Doctor states that he would never do that to her .
