Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"Susan's longing for permanence and the Doctor's withdrawal in Episode 15 foreshadow Kublai Khan's later role as a distant but powerful figure whose court represents the Doctor's only hope of returning home. This anticipation becomes concretely relevant when Tegana frames the TARDIS as a critical asset to deliver to Kublai Khan in Episode 16."

Why This Matters Across Episodes
The longer arc this connection carries
Susan's dialogue explicitly ties the group's stagnation ('we should be up there [at Kublai Khan's court]') to the Doctor's emotional withdrawal, creating a thematic and narrative setup for Kublai Khan's later involvement in the TARDIS plot. Tegana's plan in Episode 16 directly exploits this connection by targeting the TARDIS as a 'prize' for Kublai Khan, thus spanning the episode boundary through causal and thematic continuity.
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.
