Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Doctor's revelation about the Krotons' self-perpetuating slavery system (Episode 19) directly causes the Krotons to select Zoe as a 'companion' in Episode 20, as their system demands extracting the brightest minds from each generation."

Why This Matters Across Episodes
The longer arc this connection carries
The Doctor's accusation in Episode 19 that the Krotons enforce "self-perpetuating slavery" by always choosing the Gonds' brightest students leads to the Krotons identifying Zoe as a high-value target. This explains Zoe's selection in Episode 20, driven by the system the Doctor exposed.
