Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Doctor's abandonment of Ian and Barbara in Episode 12 strips them of the TARDIS’s protection and the Doctor’s guidance, leaving them vulnerable to systemic Roman threats in Episode 13—culminating in Ian being ambushed in Rome."

Why This Matters Across Episodes
The longer arc this connection carries
Without the Doctor’s oversight, the companions are exposed to external dangers (slave traders, galley masters, Roman soldiers). This causal chain demonstrates how domestic isolation leads to systemic entanglement.
