Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Doctor's obsession with the Time and Space Visualiser (Episode 30) directly enables the Daleks to track the TARDIS via seismic detectors in Episode 31, as Barbara notes the Daleks 'are on their way here' due to its electromagnetic emissions."

Why This Matters Across Episodes
The longer arc this connection carries
The Visualiser's activation and demonstration in Episode 30 establishes its danger in attracting Dalek attention, which becomes the central threat driving the plot in Episode 31. This creates a direct causal chain linking Ian's skepticism of the device to the immediate peril faced in the next episode.
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.
