Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"Susan’s possession of the TARDIS key (enabled by Ping-Cho’s theft in Episode 18) leads directly to Ian’s theft of the key from Marco Polo in Episode 19. This act triggers Marco Polo’s demand for the key and the subsequent confrontation."

Why This Matters Across Episodes
The longer arc this connection carries
The retrieval of the TARDIS key by Susan in Episode 18 culminates in Ian’s theft of the key in Episode 19. This sequence of events is the catalyst for Marco Polo’s authority asserting itself and Tegana’s abduction attempt, which are critical to the episode’s plot.
About Causal Connections
A directly causes B. The first event sets forces in motion that produce the second. These are the load-bearing connections of plot--remove one and the story structure collapses.
