Note: I digited my two names, Chiara and Benedetta, on en.shindanmaker.com/314634, finding out that "Chiara, Time Lord of Gallifrey, is now known as The Caretaker" and "Benedetta, Time Lord of Gallifrey, is now known as The Writer". It’s about time that I deserved a cameo, so why don’t make two cameos? By the way, Lara, if she was a Timelady, would be known as "The Lover".
Let’s come back to the moment when Thirteen joins the pieces of the Triangle. She suddenly finds herself on Gallifrey, the way it was before the war for the Moment. The Timelady is in front of a man who introduces himself as the Valeyard. He is so polite to tell her why he's born in the first place. When he was eight years old, the Doctor saw the Vortex (chibeco.altervista.org/Scrittu…) and caught a glimpse of him deciding to save the Earth by destroying Gallifrey, and he got so scared that he expressed the wish that the Earth was destroyed instead. This wish was the basis for the Valeyard's birth.
The First Doctor, while he was studying the Moment, accidentally pressed a hidden button, and thus the Moment, activating itself and getting to know that wish, unleashed of its mysterious powers and turned him into the Valeyard. His wife, the Writer, managed to neutralise the evil Timelord, before imprisoning him into an item that we would have known as the Triangle. Then Rassilon sent that artefact into space (but unbeknownst to everyone, it would have landed on Earth), while the Writer erased all the memories of the Valeyard from her husband. Things went back to normal, at least until our Timelord left the family and began his renegade life outside Gallifrey, following his thirst for adventure.
Now the Valeyard is understandably ready to resume from where he left. After a fight, he takes the Triangle from the Doctor’s hands and uses it to come to the real world, while the Timelady stays imprisoned inside the artefact. The Timelord is tempted to destroy the Triangle, but then he decides otherwise, as there's the possibility that killing the Doctor would cause his own death. So the Valeyard proceeds to demonstrate that he might be a part of the Timelady, but that doesn't mean that he would be as merciful as her.
Carter borrowed Missy’s former multifunction device (chibeco.altervista.org/Scrittu…) from the U.N.I.T., with the goal to use it on the Doctor as soon as she becomes the Valeyard. His powers aren't always there when he needs them, so he thought that it's better to rely on something else. But before he can use the device, the Valeyard, proving that he's extremely fast, takes it and kills him first. Then the Timelord uses the device on Jessica because she’s a sin against nature that existed only thanks to Jacqueline Natla (chibeco.altervista.org/Scrittu…). After a long hesitation, he spares Manfred's life. After all, he’s human, he’s harmless and, most of all, he knows nothing, so his death would be a waste of time and energy.
Now let’s return to the present again.
The Valeyard is going to kill Lara, while Lara is going to kill the Valeyard, but then they both hear loud thumping noises coming apparently from nowhere. S.I.M.O.N. comes on the scene, but since Kevin died before giving it further instructions, it stops. However, the robot managed to do something in the meanwhile, because its steps caused the entire place to shake and the Valeyard to drop the Triangle, which breaks and releases the Doctor.
At this point, we get to see the Caretaker again because S.I.M.O.N.'s arrival made her fall from her secret vantage point. The Valeyard proceeds to kill her, but the Doctor uses her sonic screwdriver and disables Missy's device. The Tomb Raider attempts to use the Pandora's box against the Valeyard and the Caretaker is letting her do it, but the Doctor takes her and the other Timelady into the TARDIS (Manfred already sought refuge by himself and he's safe, at least for now. That's why the Doctor didn't think about saving him as well). The Valeyard stays outside, but he knows how to keep himself busy and reactivates S.I.M.O.N. to make it destroy the machine.
Now Thirteen, looking more attentively to the Caretaker, feels the harsh sting of her own shame. She reveals to Lara that the Caretaker is her Gallifreyan daughter that she abandoned to pursue adventures across time and space (the archaeologist remembers that her own father used to ignore her because he's more interested in his own work, so she can relate to the Caretaker in that respect). What she doesn't tell is the fact that she never forgot her, so much so that, while she was the Twelfth Doctor, she thought for a moment that her daughter was behind the veil of the creature sent by Ana in "Willard’s castle" (see: chibeco.altervista.org/Scrittu…).
The Caretaker says that she never accepted that a human little girl was more important than her, even though she always recognised that Lara didn't have anyone who could take care of her, nor she didn't ask the Doctor to take care of her. She didn't even blame Amelia, who made that request, because every mother would do literally everything to save her children. The Doctor adds that she, as the Second Doctor, let her daughter kill her as an attempt to make her get some closure (if you remember, the Doctor would have done the same favour to River Serenity years later, see: chibeco.altervista.org/Scrittu…).
Suddenly S.I.M.O.N.'s assault gets interrupted by the sound of another TARDIS: it's the First Master (Remember him? See: www.deviantart.com/zaffiro84/j…)! He meets the Valeyard, who introduces himself. Obviously impressed, Missy's predecessor convinces "the new arrival" to join his side. The evil Timelord... I mean, the other evil Timelord... doesn't see him eye to eye, though. Plus, he sends a mental image of what he's done so far and what he wants to do in the near future to the intruder. The Master, scared by the things that even he wouldn’t dare to do, but recognising that there's nothing he can do to confront the Valeyard, let alone defeat him, teleports himself away from the scene. His intervention, although basically useless, at least gave the TARDIS the time to reinforce its defence mechanism against S.I.M.O.N., that now resumed his attempts to destroy it.
Lara wants to get out and kill the Valeyard, as she claims that she's destined to sacrifice herself, but this time is the TARDIS to disagree by making a hologram appear. Everybody sees an even older Lara who cheerfully waves hello, before flickering out. The genuineness of that silent sign causes the Caretaker to break down. She confesses that the archaeologist will be the Fourteenth Doctor and that she decided to kill her and destroy the Earth by awakening the Valeyard. She thought she would have done Lara a favour by killing her before she could see the Earth’s destruction before her eyes. However, the Doctor says that she saw Lara's being killed by the Valeyard, although she was doing everything in her power to prevent her assassination. Therefore, it's not possible that she would become the Doctor. Lara asks if that vision wasn't an effect of the illness that killed her predecessor in the South Pole. After a long moment of reflection, Thirteen beams with joy because now she's able to see that her adoptive daughter's right, that her destiny is to become the Fourteenth Doctor. Then the Timelady takes the Pandora's box from Lara's hands, kisses goodbye to both her daughters and exits the TARDIS, sealing its doors with a snap of her fingers. The Doctor wants to sacrifice herself to save the others. Unfortunately, she doesn't know that the Caretaker can teleport. The other Timelady does so, leaving the archaeologist alone (it happened before, see: chibeco.altervista.org/Scrittu…).
Thirteen and the Caretaker communicate with each other telepathically, devising a last-minute plan. The Doctor, now with some tears in her eyes, faces the Valeyard once again, while her daughter goes to S.I.M.O.N. and disables him successfully, without causing it any damage (after all, it was her "half-brother"'s creation).
The evil Timelord assumes that her "mother" wants to fight him and takes a defensive pose. But then the Doctor puts the Pandora's box down and walks up right up to him with open arms. Thirteen's daughter then picks up and throws it to her mother, who activates it, catching the Valeyard by surprise (yes, I became a huge fan of the "Assassination Classroom" anime, from which I got the inspiration for this part, see: www.youtube.com/watch?v=lNh8mi…). The Caretaker joins her mother and so the three of them start to get consumed by the Pandora box’s power, dying together.
Only at this point, the TARDIS opens its doors, letting Lara go and thus giving her the chance to witness this event in person. Manfred steps forward and takes the woman's hand, holding it tight. Even though he's not sure to understand what’s happening, he perceives that the woman might need his support, as she's crying. For a brief moment, Lara thinks she's seeing herself as a child and her own mother hugging her father, who finally seems to acknowledge what he neglected so far and promise that he would never leave them again (well, both Richard Croft and the Valeyard share the Twelfth’s Doctor face: chibeco.altervista.org/Scrittu…and zaffiro84.deviantart.com/journ…). This vision is the Doctor’s mental image that she sent to her adoptive daughter as her departing gift. Then the woman watches the three Timelords vanishing, before realising that Manfred is holding her hand. She bursts into tears and he silently hugs her. They both enter the TARDIS and Lara, piloting the machine alone for the first time, teleports herself and the man away from the Temple Of Ten Thousand Shadows, with the intention to ask the Cybermen to come and take S.I.M.O.N. to her house at a later time.
After taking Manfred to his home, Lara has to face the consequences of the Valeyard's actions, as she must offer her condolences to Zip's family, to Kevin's friends, to Jessica's students, to Carter's colleagues (that receive the Ankh with Horus) and, finally, to Madame Carvier. On hearing the news, the Slitheens, the CyberKing, the U.N.I.T., Sofia and Jonah visit Croft Manor and offer their condolences to the new Doctor as well. Even Sam, maybe because she saw that Lara did nothing to prevent the Doctor’s death, meaning that there’s a genuine reason why her former friend and the Tenth Doctor didn’t the Sixth Master and Amanda Evert destroyed Japan, and thus killed Sam’s father (chibeco.altervista.org/Scrittu…), calls her to offer her sympathy.
However, another woman visits Lara’s home to pay her respects to the owner: Alisha Reyes, Jocelyn’s daughter. Fourteen is genuinely surprised because her mother, resenting her and her adoptive father for not doing anything to prevent Conrad Roth's death (see: chibeco.altervista.org/Scrittu…), cut all ties with them, especially because Conrad was Alisha's father. And yet Alisha doesn’t seem to be particularly resentful against Lara, right now. The woman explains that her mother warned about her. However, neither she or her daughter ever experienced what it feels like to be on the other side, that is to be in charge of the laws of time. Alisha wants to have this experience, before deciding either she would keep resenting Lara and the Doctor for letting her father die or she would manage to find some peace. She offers to be the Doctor's next companion. Fourteen thanks her for the offer and says that she’ll get in touch with her before piloting the TARDIS again.
Lara, thinking that there’s nothing wrong with making Madame Carvier’s loneliness more bearable by letting her know Manfred, allows the latter to begin a secret correspondence with the woman. He gets intrigued by the former Timelady, and his feelings are reciprocated. The man writes that the Illuminati can keep this planet: now he wants to see every star in the universe, and he wants to see all of them with her. In exchange, he'll offer all the intelligence and the ruthlessness of a human being who was never limited by his humanity. They both have to use all their respective wits to conceive a plan to make the woman escape despite the surveillance by the Cybermen and the U.N.I.T., although they can count on Manfred’s assistant, Mr Pimms (by the way, Julian Rhind-Tutt, the actor playing Mr Pimms, worked with Michelle Gomez, the actress playing Missy/Madame Carvier, in the TV series “Green Wing”). One day the lawyer “picks her up” at the Louvre Museum where she’s working. Afterwards, the three of them build together a TARDIS-like spaceship that however doesn’t work as a time machine (well, for now). They leave and maybe one day “they shall come back. Yes, they shall come back” (I’m quoting the First Doctor’s speech: www.youtube.com/watch?v=Um5Cn5…). And it's also possible that Madame Carvier will find a way to come back to being a Timelady (I mean, she managed to live many more lives than she's given, so why not?). Manfred, despite being less experienced than his "guide" when it comes to interstellar trips, should be fine... unless he bumps into the Weeping Angels (Iain Glen, the actor portraying Manfred, starred in DW and his character, once again belonging to a sect, didn’t end well: www.youtube.com/watch?v=KEvLkd…. I think that this is how Jorah Mormont came into existence in “Game of Thrones”: the Weeping Angels did a miscalculation and sent him too much back in time ).
