Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"Kublai Khan's urgent summons ( Episode 18) disrupts the caravan's plans and prioritizes the Tardis's forced departure, setting the stage for Marco Polo's immediate compliance and Tegana's subsequent accusations of Ian's motives."

Why This Matters Across Episodes
The longer arc this connection carries
Khan's absolute authority and urgency (evidenced in Episode 18) directly cause Marco Polo's compliance with his orders and Tegana's manipulation of the situation in Episode 19. The Khan's intervention creates the political pressure Marco faces, which Tegana exploits to further her own agenda.
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.
