Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Doctor's defiance of Polo's authority in Episode 16 (secretly proceeding to find Barbara despite being ordered to stay behind) directly causes Polo's full betrayal in Episode 17, where he seizes the TARDIS to deny the Doctor his ship."

Why This Matters Across Episodes
The longer arc this connection carries
This causal link shows how the Doctor's subtle defiance in Episode 16—ignored by Polo at first—culminates in Pole's irreparable loss of trust in Episode 17. It also tracks Ian's pragmatic responses to authority conflicts (e.g., trying to reason with Polo) which anticipate his futile attempts to intervene during the TARDIS seizure.
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.
