How these two moments in the story relate
Why These Connect

Why This Matters Across Episodes
The longer arc this connection carries
Lytton's betrayal of his Dalek past and subsequent pact with the Cybermen in Episode 1 provides the Cybermen with a human ally who understands their operational strategies. This alliance is leveraged in Episode 2 when Lytton's insider knowledge allows the Cyber Leader to orchestrate the imprisonment of the Doctor and Peri, and their forced march into the Cyber Tombs, advancing the Cybermen's temporal conquest.
