Narrative Connection

How these two moments in the story relate


Why These Connect

The narrative assertion

"The Doctor’s proposal to track Zarbi to find the Menoptra (Invasion) leads to Barbara and Prapillus’s failed attempt to use the Doctor’s astral map to warn their allies in The Centre, as they must rely on his technological tools after his capture."

Why This Matters Across Episodes

The longer arc this connection carries

The Doctor’s strategic suggestion in 'Invasion' (track Zarbi, exploit tools) becomes the failed warning attempt in 'The Centre', where his absence and reliance on his tools (map, ring) drive the plot forward.

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.
