Doctor Who: The Edge of Desctruction (S01E03)

Date: Mon Jun 05 2017 Doctor Who
The Edge of Destruction is a confusing two-part story. Confusing because the characters are having memory lapses, inability to recognize each other, and none of it is explained until the end when the problem is worked out. Along the way the cast turns on each other in varying alliances. The argument between Barbara and the Doctor is very astonishing.

This serial introduces the ideas that the TARDIS console and time column directly harness the energies which drive the ship, and that the TARDIS is "alive" and somewhat self-aware.
