History Recap / DoctorWhoS37E5TheTsurangaConundrum

** While I'm not looking to a show about a magic box that flies through time and space to be correct, they didnt even get close. Particle accelerators cannot accelerate atoms. You need ions. Also, you can't create energy by creating antimatter. You waste a lot of energy producing it, as most of it goes off into other particles that are not useful. Only a very small fraction of the initial energy you put in comes out as positrons. You get that energy out again when you get them to annihilate with electrons, but it is still only a minuscule amount of the energy you put in in the first place. That is not because we can't yet build good enough particle accelerators, that is a fundamental law of physics. You just can't get energy from nothing.

The one with [[MisterSeahorse the pregnant man]].

* HeelRealisation: The Doctor when Atmos points out how selfish she's being by trying to turn the ship around to get back to the TARDIS when it's taking others to a hospital.

* HeelRealisation: The Doctor is so focused on turning the ambulance ship round so she can get back to her TARDIS before someone salvages it, it takes Astos pointing out that she's being incredibly selfish as they have other casualties who need to get to the hospital.

* HeroicSelfDepreciation: Subverted when the Doctor initially denies being the one with a chapter in the Book of Celebrants, then can't resist adding that it was actually an entire volumne.

* YouAreBetterThanYouThinkYouAre: Astos's last words to Mabli are encouragement for her to face this crisis because she is capable of it.

* BatmanCanBreatheInSpace: The Pting is able to cross the vacuum of space without suffering any obvious ill effects.

* ThrownOutTheAirlock: The Doctor ejects the Pting from the ship after it eats the bomb this way.

* TheUnreveal: Early on, Astos notes something surprising in the Doctor's medical information, but it's not revealed what he saw.

As the Doctor works to figure out what the Pting wants and get everyone safely to Rhesus 1, the other patients have their own problems: Yoss is about to have a baby he's not sure he wants to keep, and celebrated war hero General Eve Cicero is trying to hide the truth about her medical condition from her brother and everyone else. The Doctor eventually deduces that the Pting feeds on energy, so as Yaz and android Ronan defend the ship's antimatter core, and Graham and Ryan are roped into serving as Yoss' doulas (a real-world term for a non-medical assistant for a birth) while Mabli delivers his baby. The General sacrifices herself to fly the ship to safety through a quicker but more difficult and dangerous route, which her heart can't take. The Doctor feeds the ship's self-destruct bomb to the Pting, giving it a very good meal that should keep it from endangering anyone else for a long time, and the General's brother takes the ship home for the final stretch. At the end, as the ship is being decontaminated before everyone can be admitted to the hospital, they gather round to say a few words for General Cicero.

* BizarreAlienReproduction: Among Gifftans, men give birth to boys and women give birth to girls. We don't see how the women give birth, but males are pregnant for only a week, have a "birthing sac" that must be painlessly cut open to extract the baby, and are born with two umbilical cords. For his part, Yoss' reaction to finding out that human reproduction doesn’t work like Gifftans' is a weirded out "Ew".

* {{Foreshadowing}}: Ryan discusses his mum's death from a heart attack, and the strain this put on his relationship with his dad. This foreshadows General Cicero's death from pilot's heart, and Yoss' reluctance to raise a child.

* SawItInAMovieOnce: Graham cites having seen every episode of ''Series/CallTheMidwife'' as his experience when asked to be one of Yoss' birth partners. Unfortunately, he always had to look away at the squishy bits...

* CallBack: [[Recap/DoctorWhoS30E10Midnight An automated vehicle is attacked by a dangerous alien entity after being steered by the autopilot onto a route that it's never taken before.]]

* IKnowMortalKombat: Graham mentions that he knows how to properly assist with childbirth thanks to watching ''Series/CallTheMidwife''. Later {{subverted}} when he mentions to Ryan that he actually looked away during the gross bits.

** Another one, that really shows the Pting's invulnerability if you get it: A weapon called a "staser" is used, and can only stun it briefly. Stasers, introduced in [[Recap/DoctorWhoS14E3TheDeadlyAssassin "The Deadly Assassin"]], are Time Lord weapons which prevent regeneration, and can leave the victim an unrecognizable burnt husk. A weapon created by the most advanced civilization in the universe at the height of their power that is ''designed to kill the unkillable'' can only give this thing a nice refreshing nap.

* FutureImperfect: For some reason, "Avocado Pear" has gone down in history as the name of one of Earth's greatest heroes, at least in Gifftan records. Graham and Ryan correct Yoss that those are foods. Of course, between the 21st and 67th Centuries there’s definitely some time for an Earth hero of that name to appear — with the popularity of avocados and strange names at the time of the episode airing, it wouldn’t even really be surprising if there was a baby with the name Avocado in the present.

** [[Disney/LiloAndStitch The creature is a malevolent little gremlin about the size of a human baby, completely adorable in appearance and possessing a seemingly programmed instinct to destroy everything it comes across. It also happens to be impossible to destroy or contain by any known means.]]

* YouAreBetterThanYouThinkYouAre: Astos' last words to Mabli are encouragement for her to face this crisis because she is capable of it.

* CelebrityParadox: Graham mentions ''Series/CallTheMidwife'', a show that shares several actors with ''Doctor Who'', including former lead actress Creator/JessicaRaine, who doubles down on the paradox as she played Verity Lambert, ''Doctor Who'''s original producer, in the docudrama ''Film/AnAdventureInSpaceAndTime'', about the ''making'' of ''Doctor Who''.

** Upon learning she's in the 67th century, the Doctor remarks that it's a rather tumultuous period of history in the middle, but works out in the end. Amusingly, but almost certainly coincidentally, it ''is'' the period of Creator/BigFinish's [[AudioPlay/DalekEmpire Dalek Empire III]], which is certainly tumultuous.

** The Doctor notes the 67th Century is alright, but a bit bumpy in the middle. Although it's almost certainly coincidental, this is exactly the period of ''[[AudioPlay/DalekEmpire Dalek Empire III]], and the Dalek empire remnant's attack on human civilisation.

* KillerRabbit: The pting looks adorable but is NighInvulnerable, has a lethal toxic touch, and endangers an entire starship by eating it.
* TheKnightsWhoSaySquee: The Doctor has a moment of squeeing over General Cicero, who returns the gesture upon learning that she is talking to the Doctor.
