Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Doctor’s failed gamble in Assassin at Peking, which shatters Susan’s hope, directly causes Arbitan’s blackmail ultimatum in The Sea of Death. The loss of the TARDIS as a safe haven forces the group into Arbitan’s trap."

Why This Matters Across Episodes
The longer arc this connection carries
This connection centers on the TARDIS as a symbol of safety and freedom. Its loss in Episode 20 catalyzes the events of Episode 21, forcing the Doctor to adapt to new constraints and rely on his companions’ ingenuity.
