Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The TARDIS malfunction (fluid link breaking) from Episode 5 leads directly to the group's need to enter the alien city in Episode 6, where they search for Barbara."

Why This Matters Across Episodes
The longer arc this connection carries
This is a direct causal chain: the mechanical failure in the earlier episode forces the companions into the very city they were trying to avoid, setting up their search for Barbara and the events of Episode 6. The Doctor's lie about the fluid link's condition creates a moral breach that will haunt him when it's exposed.
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.
