Why This Matters Across Episodes
The longer arc this connection carries
In Episode 20, the Doctor declares the necessity of capturing the Dalek time machine or similar tool, indicating a plan to counter the Daleks. In Episode 21, he activates the time destructor, which inadvertently activates its damaging effects on Sara. This causal chain traces the Doctor’s proactive intent to an unintended consequence on his companion.
