History Recap / DoctorWhoS2E7TheSpaceMuseum

* AbsenteeActor: Creator/WilliamHartnell was on holiday for episode 3, so he only appears in the reprise of episode 2.

* InvisibleMainCharacter: The Doctor and companions throughout episode 1.

* ScrewDestiny: From episode 2 onward, the TARDIS crew's goal is to avoid being trapped in the museum cases.

* TimeyWimeyBall: the theory of time travel used in this episode is unclear. At some point, the Doctor and his companions landed on Xeros and through an unknown sequence of events were turned into exhibits for the Moroks' museum. They also arrive, walk around on Xeros while not really being there at all while an instrument in the TARDIS is stuck, and then when they finally "arrive", the display cases disappear. It almost appears to be a case of the TARDIS offering a glimpse into an alternate possible timeline rather than something that actually happened as a result of time travel.

* DiscoveringYourOwnDeadBody: The Doctor and his companions land on a planet but they're JustOneSecondOutOfSync. While they're out of sync they wander around the museum and find their own stuffed bodies on display. When the timelines resync they go on the run from the authorities to make sure that they don't wind up dead.

The one where the Doctor is a walrus.

* AllThereInTheManual: In the novelisation, the Morok commander is named as Ogrek and the Morok that Ian captures is named Pluton. Pluton saves Dako and Gyar's lives by telling his superiors they are dead; in return, the Xerons spare him when they storm the headquarters and he accompanies them when they kill Lobos and Ogrek.

** That's in the serial. In the novelisation, the lie detector doesn't even require the correct answers, just the truth, so Vicki doesn't even need to reprogram it. She tells it exactly who they are, that they have no authorisation to remove weapons from the armory, and that they're taking the weapons for the purpose of "Revolution!". The machine promptly lets her in.

* AsYouKnow: The second episode is notorious for this. After a really scary and surreal first episode in which the characters wonder around an invisible museum and witness their own corpses, the second episode kicks off with an overweight, middle-aged RubberForeheadAlien delivering a ton of CallARabbitASmeerp {{Technobabble}} beginning with "As you know...". This is a rare example of the speech managing to be unnecessary to the other character and incomprehensible to the audience at the same time. Helpfully pointed out by Robert Shearman on a DVD special feature, in which he ponders whether the sequence is "badly written' or 'amazingly badly written".

* OoohMeAccentsSlipping: Richard Shaw, who spoke with a Cockney accent, was cast as Governor Lobos, but was asked to deliver his lines in BBC English. His accent slips only once, when he bellows at an underling to use "maximum securi'ee!"

* AbsenteeActor: The Doctor does not appear in Episode 3 (save for the reprise), as Hartnell was on holiday. In-universe, the Doctor's absence is due to him being captured and taken to the Preparation Room in order to be turned into an exhibit.

* DeadGuyOnDisplay / DiscoveringYouOwnDeadBody: Which tells the party that they had best leave before they end up like this.

-->-- '''A Morok''', in "one of the great stupid lines of Doctor Who."

* TrailOfBreadCrumbs: Ian gets the idea of unraveling Barbara's cardigan to mark the corridors when they get lost in the museum, like [[ClassicalMythology Theseus]].

The TARDIS heads for the future again, and manages, because of the TimeyWimeyBall, to arrive at a space museum where it and its current occupants are exhibits. The museum is that of the conquests of the great Morok empire, and the planet is Xeros, one of the many under the dominion of the Moroks.

Time sorts itself out again, and then the TARDIS properly arrives on Xeros and the Doctor, Ian, Barbara and Vicki have to prevent themselves becoming exhibits. This is mainly accomplished by assisting the native Xerons in smuggling in arms, following which they rise up and free themselves from the Moroks.

* WhamLine: Ian states just a bit ago that everyone's walking on dust. Normally, this would be nothing more then a CaptainObvious moment, but he then he points out something ''not'' so obvious;
** ''"Then why aren't we leaving any footprints?"''

* SneezeOfDoom: Vicki tries to hold in a sneeze while the gang are hiding from the Xerons. Barbara stops her the first time, but then she makes a loud one. However it turns out not to matter, as nobody can see or hear them anyway.
