Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"Tegana's chess metaphor metaphorically foreshadows his strategic manipulation of Marco Polo in Episode 17, where he effectively 'checkmates' Polo by seizing control of the TARDIS."

Why This Matters Across Episodes
The longer arc this connection carries
Tegana's metaphor in Episode 15 about the 'game of strategy' and 'shah mat' (checkmate) directly parallels his later, more overt manipulation of Marco Polo in Episode 17. This escalates the conflict from Tegana probing Polo's vulnerabilities to outright seizure of the TARDIS, demonstrating Tegana's long-term plan to undermine Polo's authority.

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.
