History Recap / DoctorWhoNSS4E10Midnight

** He also mentions a friend in another universe, which COULD refer to [[Recap/DoctorWhoS18E5WarriorsGate Romana and K9]] rather than [[Recap/DoctorWhoNSS2E13Doomsday Rose]], depending on how you take the ExpandedUniverse as canon, but as he's stated time and again that every Time Lord is dead, it's likely Rose.

* DirtyCoward: The passengers will eventually believe, follow or ''sacrifice'' anyone to escape the horrors around them.

* SayingTooMuch: The entity really should have just stopped flaunting the fact that it had the Doctor's voice- if it did, [[NearVillainVictory it would have succeeded]]. Even if everyone was too thick to notice Sky's sudden smugness, ''eventually'' the Hostess figures it out [[SomethingOnlyTheyWouldSay when she hears "Allons~y"]].

* CanOnlyMoveTheEyes

* HobbesWasRight: Oh yes he was. Bonus points for the [[MeaningfulName professor being named Hobbes]].
* HumansAreTheRealMonsters: Very uncharacteristic for this show, and especially this Doctor, who up until now has had a great love and admiration for humans as a species. This episode flips that all upside down, leaving the Doctor shaken and disturbed in the aftermath. It can be argued that the Tenth Doctor is never quite the same after this experience.

* JerkassHasAPoint: The Hostess is the first one to recognise just how dangerous the possessed Sky could really be, and to insist that they throw it out of the craft; as Creator/RussellTDavies points out in the Confidential, [[spoiler: she's proven absolutely right and that's really the only thing they could have done.]]

** This episode was arguably the beginning of an arc which saw the 'breaking' of the Tenth Doctor, culminating in his regeneration in 'The End of Time'.

** As well as everything that goes wrong for Ten in this, nobody believes him when he says his name is "John Smith".

* RightForTheWrongReasons: According to Creator/RusselTDavies, the Hostess was ''right'', throwing Sky out as soon as possible was only thing they could have done, awful as it is. Instead of it coming off as a pragmatic ColdEquation justification, though, she seems scared out of her wits and suggesting it out of panic rather than reason.

* HeHadAName: Variation. No one knew the hostess name when the doctor asked at the end.

** Also, before the bus gets moving, the Hostess mentions that, should the need to use the emergency fire exit arise, "passengers [go] first", a dumb joke on the fact that the planet has no air. The Hostess is the only character (aside from the Monster of the week) to actually use that door.

* BuryYourGays: Played with here by gay author Creator/RussellTDavies. Sky's ex-partner was female, and the hostess notably addresses her passengers as "ladies and gentlemen and variations thereupon".[[note]]This is presumably more because the passengers might not all be human; the Doctor isn't, for a start.[[/note]] Neither of these things is PlayedForLaughs -- it's just considered normal by everyone and never commented on. The fact that Sky dies isn't because she's not straight, but simply because within the context of the plot, the Doctor relates to her most and tells her he [[Recap/DoctorWhoNSS2E13Doomsday lost someone too recently]].

A "companion-lite" PsychologicalHorror BottleEpisode by RussellTDavies, written as a contrast to the "Doctor-lite episode" that directly follows it.

* PsychologicalHorror

* ChekhovsGun: The Doctor's {{catchphrase}}s.

* DemonicPossession: Kinda-sorta.

* SomethingOnlyTheyWouldSay: "Allons-y!" finally tips off one of the passengers that it's not Sky talking, it's the alien, stealing the Doctor's voice.

* WhatCouldPossiblyGoWrong: The Doctor gets this exact line in the teaser. He sounds like he almost ''wants'' something to go wrong when he says it. He will regret ever wanting this by the end of the episode.

* IronicEcho: "Don't. Don't do that", is one for previous episodes.

* JustAKid: Jethro's mother dismisses him as "Just a boy" when his opinion differs from her own. Ironic, because she had ''just'' sought out his opinion and [[HumansAreBastards didn't dismiss him when he agreed with her.]] Especially ridiculous because he looks like he's at least seventeen (not to mention Colin Morgan was 22 when this was made, although he has yet to actually look his age).

* BittersweetEnding: Big time. This episode does not end on a happy note.

* EldritchAbomination: One theory for the nameless ''thing'' that succeeds where gods and monsters have failed in utterly '''breaking''' the Doctor.

* EvilGloating: This is the alien's undoing.

** Also, when the Doctor is possessed he mentions darkness and diamonds, which is something the Toclafane talked about. What do these foreshadow? TheMaster.

* HeHadAName: Variation.

** Same with the creature.

* NumberOfTheBeast: Jethro sadistically tells the creature "six-six-six" so it will repeat the number back to him as though it were a demonic force.

* UltimateEvil

* IdiotPlot: Not the ''whole'' story, but the passengers are quick to assume that the monster merely "moved on" to The Doctor when it's previous host sounds ''way'' to smug for someone who's been freed of [[DemonicPossession Alien Possession]].

* {{Troll}}/NightmareFetishist: Jethro decides to say "[[NumberOfTheBeast six-six-six]]" to the creature out of dark curiosity. He gets rebuffed by his parents for doing so and smiles for successfully pissing them off.
