Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"Prapillus's speech about 'using our brains and not our wings' (Episode 20) directly enables Barbara and Prapillus's later attempt to transmit warnings via the Doctor's astral map (Episode 21). This intellectual strategy from Episode 20 directly informs their communication attempt in the next episode."

Why This Matters Across Episodes
The longer arc this connection carries
The thematic shift from physical wings to intellectual strategy in Episode 20 creates the foundation for Episode 21's reliance on technology (astral map) rather than physical confrontation. Barbara's role as the bridge between these strategies shows her developing understanding of Vortis's alien nature.
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.
