Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The TARDIS stopping after its hijack in Episode 17 and Vicki’s investigation (Act 1) leads directly to her being separated and left alone when the Zarbi breach the TARDIS. This isolation is the precondition for the entire Animus interrogation sequence in Episode 18, where the Doctor and Vicki must navigate threats without Ian or Barbara."

Why This Matters Across Episodes
The longer arc this connection carries
The breach doesn't happen until the TARDIS is stopped and empty. Therefore, the investigative standoff in Episode 17 is the causal trigger for the entire peril in Episode 18. Without Vicki’s exploration and the TARDIS’s vulnerability, the Zarbi could not have infiltrated and captured them.
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.
