The Lure and Cost of Legacy
The Zygons frame their invasion as the culmination of a long-planned legacy, invoking destiny and inevitability to justify their conquest. Broton repeatedly invokes the Skarasen as an unstoppable force—an instrument of terror that embodies Zygon destiny. Yet this legacy is revealed to be a fragile construct: the Doctor undermines it by deflecting the monster’s rampage, exposing the Skarasen’s vulnerability through strategic manipulation. Similarly, the Brigadier operates within a legacy of military discipline and secrecy, but the Doctor’s interventions force him to question the efficacy of old protocols. The theme suggests that legacy, unexamined, can become a prison—only through innovation and courage can its destructive chains be broken.
