Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"Zoe's immediate departure with the Doctor from Earth (following the Cybermen invasion) enables their arrival on the Krotons' planet in Episode 19. The TARDIS materializes directly after Episode 18's events, setting the stage for the new alien encounter."

Why This Matters Across Episodes
The longer arc this connection carries
The Doctor's imminent departure in Episode 18 is the direct cause of the TARDIS's materialization in Episode 19. This causal link stitches the two episodes together, showing the Doctor's pattern of rapid response to crises and Zoe's continuous role as his companion through transitions.
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.
