Journey to the Centre of the TARDIS (TV story)

Journey to the Centre of the TARDIS was the tenth regular episode of the seventh series of Doctor Who produced by BBC Wales. It was notable for marking the first time the Doctor told Clara Oswald about her multiple lives and deaths.

Synopsis
Clara is lost in the depths of the Doctor's TARDIS which is damaged and captured by intergalactic salvage crew Van Baalen Bros., who want to sell it for scrap. However, the Doctor threatens to destroy the TARDIS by putting it in lockdown and activating the self-destruct if the salvage crew doesn't help him find Clara.

Plot
The android Tricky is polishing a part inside the Van Baalen Bros. salvage ship when the system alerts him and Bram that there is salvage to be verified. Bram believes that it's just space junk, but his brother Gregor wants to go for it, anyway. They suit up.

Meanwhile, the Doctor is hounding Clara to attempt to bond with the TARDIS, but she flatly refuses to talk to a piece of machinery. He gets her to agree to try flying it, and to make it easier, he puts it into Basic Mode. She flips some levers and suddenly, the ship shudders, losing then regaining power, and the music that the Van Baalen ship had been playing starts to play. The scanner screen cracks and shudders, and the Doctor starts to work the controls more frantically. He can't get the shields up, and the salvage ship's magna-grab nearly has them. The Doctor forces a lever up, and something in the TARDIS console explodes, throwing them both back. Clara asks him to tell her that there's a button he can press to fix it. He says, "Oh, yes, big, friendly button." Clara asks if he's lying to make her feel betters, and he is. A hand-sized metal object rolls towards Clara, who picks it up. It burns her right hand, and she drops it.

The machinery of the salvage ship pulls the TARDIS into a bay, and, believing it to be a derelict escape pod, the brothers attempt to cut into it, but are unsuccessful. Tricky's bionic eyes pick up signs of a living being - a pair of shoes sticking out from under the wreckage. They withdraw, and Gregor is whispering a cover story to the other two when the Doctor pops in, saying it's not polite to whisper. Bram says that they found his ship drifting and the Doctor immediately corrects him, saying an illegal magna-grab broke his ship, which would have been safe if he hadn't disabled the defenses. He shows them that he found the remote to the magna-grab in Gregor's pocket.

The Doctor realises that Clara is not with them. Realising that she's still inside, he bolts for the TARDIS, but Tricky stops him, telling him that the fuel is leaking. The Doctor spots respirators, then talks the salvage crew into going with him, promising the salvage of a lifetime within the ship.

Cast

 * The Doctor - Matt Smith
 * Clara Oswald - Jenna-Louise Coleman
 * Gregor Van Baalen - Ashley Walters
 * Bram Van Baalen - Mark Oliver
 * Tricky - Jahvel Hall

Books

 * The History of the Time War appears to be a book unfolding the history of the Last Great Time War. Clara read the book while in The TARDIS' library. She later implies that the Doctor is mentioned in it by name.
 * The library also contains the Encyclopedia Gallifreya, which is knowledge in liquid form.

The TARDIS

 * Tricky mistakenly describes the TARDIS as "some kind of escape pod."
 * The TARDIS' sentience is alluded to yet again; and when the salvage team tries to open it, Tricky senses that she seems to "suffer".
 * The Doctor tells Clara that the TARDIS is not like a cheese grater.
 * The TARDIS display that declares "Engine Status: Overload" also mentions the console room, Eye of Harmony, library, observatory, and Arch-Recon. These rooms are all seen in the episode, although Arch-Recon is named fully as Architectural Reconfiguration system.
 * Clara sees the swimming pool while wandering through the TARDIS.
 * The Doctor states that the TARDIS is "infinite."

Individuals

 * Tricky thinks he's an android because of a joke his brothers told him.

Story notes

 * The name of the episode was influenced by the novel Journey to the Centre of the Earth.
 * This is the first televised story to include the word "TARDIS" in its title.
 * This episode aired on Jenna-Louise Coleman's 27th birthday.
 * At seven words long, this episode shares the record for the longest televised story title to date with The Doctor, the Widow and the Wardrobe.
 * Sarah Louise Madison, Ruari Mears and Paul Kasey (Time Zombies) are credited on-screen, but not in Radio Times.
 * Although the action was normal in the classic series, this is the first time since the series restarted that the Doctor has closed the TARDIS doors from the console, rather than manually shutting them.
