Doctor discovers Tractators rescue purpose

Moving deeper into Frontios’ treacherous caves, Tegan voices frustration at the Doctor’s cryptic hints while they evade an approaching Tractator gravity beam.

Tegan’s wariness shifts as the Doctor’s quick assessment reveals an unexpected alignment between their survival needs and the planet’s deadly custodians. The moment foreshadows the wider conspiracy centered on Plantagenet and the Tractators’ manipulation of Frontios’ survivors, threading Tegan’s growing trust in the Doctor’s instincts into the unraveling mystery of the missing colonists. key_dialogue: [ DOCTOR: If only we knew more about these creatures.
