History DoctorWho / TropesTToZ

* ThreesomeSubtext: Pretty much any time the Doctor has two companions (especially in the new series), this comes up. Favourites include Two-Jamie-Zoe (SleepCute), Nine-Rose-Jack (plenty of flirting, all three pairings kiss in their last episode) and Eleven-Amy-Rory (the Doctor resolves the love triangle issue by matchmaking them and whisking them both off after their wedding - then he marries their daughter, which complicates things...)

* TheXOfY: By far the single worst abuser of this trope, guilty of it no less than '''''147 times'''''. Having trouble coming up with an episode title? Try mixing and matching these ones that ''already'' exist.

* TookALevelInBadass: The Creator/RussellTDavies era has a recurring theme of the Doctor turning the companions into badasses.

** When the [[CloningBlues Ganger!Doctor's]] personality briefly reverted through previous incarnations, he channelled the Tenth's voice for a few seconds, before quickly reasserting control with "Nooo! ''Let it go!'' We've ''MOVED ON!''"

* TranslatorMicrobes: An omnipresent device: the TARDIS's telepathic field is the reason most of the dialogue is rendered in English regardless of the setting. The intricacies of this -- how it works both ways, what happens when you try and actually speak the language being translated directly (as Donna wonders in [[Recap/DoctorWhoS30E2TheFiresOfPompeii "The Fires of Pompeii"]]), and why humans don't all hear each others' languages as their own mother tongue whenever the TARDIS happens to be on Earth, are {{Justified}} by the TARDIS being [[SapientShip sentient]] -- what, for whom, and how she chooses to translate is down to her own personal whims. Other cases of dialogue in English can only be chalked up to TranslationConvention, such as Time Lords speaking among themselves when there are no humans present.

* TeethClenchedTeamwork: Despite being on the same side, the Doctor and UNIT fall into this. It varies on the incarnation, but the Doctor generally disapproves of their military tactics i.e. "shoot first ask later", while UNIT barely tolerates his arrogant attitude. It was especially prominent in the Creator/RussellTDavies era where UNIT's increased aggression (in the name of [[UsefulNotes/TheWarOnTerror Homeworld Security]]) was met with nothing less than hatred by the Doctor (''Series/{{Torchwood}}'' shows them in an even darker light, just ask Tosh). The Creator/StevenMoffat era reconciled them, but UNIT was still willing to go extreme measures (like '''nuking London''' to save the rest of the world from an alien invasion. And they have a tendency to kidnap the Doctor since to ensure his cooperation, whenever they can find the TARDIS.

* TalkativeLoon: One of the possible temporary side effects of a Time Lord's regeneration, as evidenced by the Fourth, Seventh, Tenth, and Eleventh Doctors, as well as the Master's only on-screen regeneration.
* TalkingLightbulb: Most famously true of the Daleks, whose paired dome-lights flicker as they speak. Also seen in Ood slaves, who carry light-up globes that facilitate their communication with humans.

** The episode "[[Recap/DoctorWhoS27E7TheLongGame The Long Game]]" has a belated [[AC:TitleDrop]]; it ends without any reference to what the title meant at all. Not until the Doctor returns to the same location 100 years later, in "[[Recap/DoctorWhoS27E12BadWolf Bad Wolf]]", does he realise "Someone's been playing a long game." (The title of "Bad Wolf" had, of course [[ArcWords already been dropped all over the series]].) And of course not mentioning the "Long Game" of the title until a later episode is itself a reference to the concept of the long game.
** And obviously, there were a few [[IncrediblyLamePun blink-and-you-miss-it]] Title Drops in "[[Recap/DoctorWhoS29E10Blink Blink]]".

* TooStrangeToShow: This was the reason that Creator/RussellTDavies and Creator/StevenMoffat declined to depict the [[GreatOffScreenWar Time War]] largely in the series, only showing the final days of the war in "[[Recap/DoctorWho50thASTheDayOfTheDoctor The Day of the Doctor]]". They both felt they couldn't do the event justice because it was so apocalyptic that the setup given in dialogue couldn't be realized.
* In the episode "[[Recap/DoctorWhoS28E13Doomsday Doomsday]]", the Void is a place that cannot be described through normal means. The Doctor says that nothing exists there; no up, no down, no dark, no light, no physics, not even time as a concept. All we see of it is a large white wall of light-emitting energy acting as a portal into it.

** Richard Franklin was unable to appear in "[[Recap/DoctorWhoS10E1TheThreeDoctors The Three Doctors]]", so Captain Yates' role was given to Sgt. Benton, whose role was assigned to a new character, Corporal Palmer.
