I have yet to see a robot that can climb.
Just when you thought you knew what was coming next on Doctor Who, the series proves it can still deliver surprises at tea time. Looking beyond the normal stable of writers—and the normal monster-and-threatened-base storyline—the producers brought in an outsider, Peter Ling, for the wholly unexpected “The Mind Robber” (Series Production Code UU), an extended rumination on the meaning of fiction and reality and the interplay between them. And, don’t worry, there are menacing robots, too. This is still late ’60s Doctor Who, after all.
The cliffhanger from the end of “The Dominators” sees the TARDIS about to be swallowed up by lava, but sadly, the fluid links simply can’t handle the load, and they begin to spew poisonous mercury vapor once more and prevent a normal departure. (Must have been an off-brand of mercury they loaded up with at the end of “The Wheel in Space.”) The only way out is by using the “emergency unit,” which the Doctor is hesitant to install, because “it moves the TARDIS out of the time-space dimension, out of reality.” Jamie forces the Doctor’s hand (literally, by smashing down on his hand and triggering the device) and off the TARDIS goes, to nowhere.
The Doctor wants nothing to do with nowhere and with nothingness, so he instructs his companions to stay in the TARDIS while he makes repairs in the Power Room. He’s positively spooked, in fact, jumping with fright when Zoe walks in during the repairs. Possibly this is due to her having changed into a sparkly jump suit, but more likely has to do with his nervousness at being outside the time-space continuum. Nothing good comes from nothingness. As he tells his pant-suited companion, “It’s only the unknown that worries me, Zoe.”
The TARDIS has been outside of time and space before, arguably in “The Edge of Destruction” and, more definitively, in “The Celestial Toymaker.” As in the latter story, there’s a force out there in the nothingness that tempts the Doctor and his companions out by manipulating the TARDIS scanner, this time showing images of their homes, Scotland (for Jamie) and the City (for Zoe). And no sooner do Zoe and Jamie succumb to the temptation than they find themselves in a Beckett play.
