Why This Matters Across Episodes
The longer arc this connection carries
The Doctor's plan to escape is directly thwarted by Polo's concealment of the keys, creating a zero-sum conflict where the travelers must act covertly to regain control of their lives. This mirrors the Doctor's earlier frustration but with higher stakes.
