Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"Vicki's unresolved grief over Barbara killing Sandy in Episode 11 leads to her absence during the Roman ambush in Episode 12, as Barbara and Ian claim 'she and the Doctor have gone away', directly causing their isolation and vulnerability."

Why This Matters Across Episodes
The longer arc this connection carries
Vicki's emotional rupture with Barbara in Episode 11 results in her immediate departure with the Doctor in Episode 12. This creates a narrative vacuum where Vicki is absent during the ambush, forcing Ian and Barbara to face the slave traders alone. It's a direct consequence of the trust fracture established earlier.
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.
