“As we learn about each other, so we learn about ourselves.” – The Doctor
As the third serial of Doctor Who comes to an end, the show finally reaches something of an equilibrium. No longer are Ian and Barbara prisoners, but rather full-fledged “companions” in the modern sense of the word. If the show had not been picked up for a full season, it would have ended here: as a fun little science fiction adventure told in thirteen parts. But, as we know, what they really did with these early episodes was launch a sensation.
As the strange happenings continue on the TARDIS, our companions argue with each other until the true danger is discovered. With their collective lives in the balance, only then do they come together to save themselves. It’s a deep dive into the nature of our key relationships, both with the Doctor and with each other. The tension is high, but the ultimate resolution is surprisingly low tech. We are also left with a key but enduring mystery: is the TARDIS alive? More thoughts on this after our recap.
