History Recap / DoctorWhoS30E13JourneysEnd

In the TARDIS, Doctor-Donna is starting to exhibit some problems, as her behaviour becomes hyperactive, and she literally can't stop talking or focus on a single matter. This leads to the most SadisticChoice the Doctor's ever had to make. Donna's Time Lord brain is overloading her human body, which, as the Doctor solemnly explains, is the reason why there never has been a human/Time Lord fusion before. Either [[YourHeadAsplode her head asplode]], or the Doctor wipes her memories of everything she's done with him going back to her first appearance. The Doctor knows there's only one option to save Donna's life. She begs and pleads, but the Doctor takes her into his arms and gently wipes her memories. She can never remember who she was, or anything about the Doctor, or she'll ''burn up''. She goes back to the way she used to be, and she can never know about how much she saved the universe or how amazing she was. The Doctor takes her home, where she turns into her old self... her ''old'' old self, loud and crass... And [[FridgeHorror someone's going to have to tell her that she's missed two full years, and that her fiancée and her father are dead]], that is, if the memory-wiping was thorough enough to blank out that much. The Doctor tells Donna's mother to be ''nice'' to her for a change, bids Wilf farewell and steps out of their lives. (For now.)[[invoked]]

* DragonInChief: Inversion. The Doctor mocks Davros as the Daleks' "pet", and he is actually a prisoner, kept alive only to help them construct the Reality Bomb and will likely be exterminated once the plan is complete. He is not TheDragon in any meaningful sense, but nonetheless he is a minion serving as TheFace for the true BigBad, the Supreme Dalek.

* HybridPower: The Doctor undergoes a "biological meta-crisis" in which he uses regeneration energy to form a clone which has some of Donna's personality. More importantly, the same process gives Donna the Doctor's mental prowess, which, combined with her "gut instinct" as a human, makes her a hypergenius capable of things even the Doctor would never think to do. Unfortunately, the human-Time Lord meta-crisis proves to be unstable and would kill her if she didn't have her [[LaserGuidedAmnesia memory erased]].

* OmnicidalManiac: "The DESTRUCTION! OF REALITY! ITSEEEELLLLLFFF!!!" Davros has been one for quite some time. Now that he's capable of destroying reality, [[LargeHam he's overjoyed]].

** A couple of grammar mistakes in the German, and while "Exterminieren" is a German word, it's rarely used in that language. [[FridgeBrilliance If you consider the in-universe perspective then they're technically not grammar mistakes]]; the Daleks are aliens and have, according to the series at least, never spoken German before. A few errors can be allowed.[[invoked]]
