Why This Matters Across Episodes
The longer arc this connection carries
Hrostar explains Barbara's imminent fate—being taken to the Crater of Needles to be put to work—as a result of Zarbi enslavement (Ep 17). This directly foreshadows the events of Episode 18, where the Doctor intercepts a Menoptra transmission and determines the Crater of Needles as Barbara's prison, motivating his emergency plan to rescue her.
