Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Doctor's warning about the consequences of using the TARDIS key (Episode 17) directly leads to Marco Polo hiding the keys and extracting vows of secrecy (Episode 18), as Polo now acts out of fear and mistrust."

Why This Matters Across Episodes
The longer arc this connection carries
This illustrates the escalating stakes of the TARDIS key throughout the narrative arc, with each episode showing a different character's interaction with it (Tegana's manipulation, Marco's seizure of the TARDIS, Polo's hiding of the keys) and Susan's central role as both a passive observer and active participant in these dynamics.
