Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"Arbitan's assassination in Episode 21 forces Barbara into a vulnerable position, materially causing her separation and placement in Morphoton's illusion in Episode 22. This escalates the stakes for the crew, isolating Barbara and forcing her to confront dangers alone."

Why This Matters Across Episodes
The longer arc this connection carries
Arbitan's death precipitates the crew's fragmentation and Barbara's isolation in Episode 22. This causal chain intensifies the narrative tension and drives Barbara's personal conflict—her struggle with loyalty and her growing willingness to intervene in historical events despite the Doctor's moral constraints.
