Theory:Doctor Who television discontinuity and plot holes/The Caves of Androzani


 * It is clear when seeing the Doctor through the eyes of the robot in episode two that he is wearing his hearts on the outside of his jacket.
 * The android is seeing through his jacket except for an outline of it.''


 * In one moment of the regeneration scene, the Doctor's head is on Peri's lap, in the next he is lying flat on the floor with Peri nowhere near him.
 * After the regeneration we see her crouched by the door.
 * She moves, likely having been scared by the lights/energy release.''


 * When Stotz is firing at Sharaz Jek at the conclusion of part Four, part of his gun splits in two and falls off.
 * Why does Stotz have to kill his crewmates in episode 4?
 * The practical reason is that they could be a liability or threat, as they know him and his immediate plans. He also has a long-standing feud with at least one of them, and appears to enjoy killing them.''
