Narrative Connection

Why These Connect
The narrative assertion
"Vicki’s discovery of Barbara’s disappearance (Episode 16) directly leads to Barbara’s absence being a point of tension when the Zarbi breach the TARDIS (Episode 17)."

Why This Matters Across Episodes
The longer arc this connection carries
Barbara’s sudden absence in Episode 16 creates a gap in the TARDIS’s stability—both emotionally and narratively—which allows the Zarbi to exploit the ship’s vulnerability in Episode 17. Vicki’s plea for help and confusion about Barbara’s whereabouts set up the Doctor’s accusatory interrogation in Episode 17, reinforcing Vicki’s isolation and the breakdown of the companion group.
