Narrative Connection
How these two moments in the story relate
Why These Connect
The narrative assertion
"The Doctor warning against informing the Time Lords about their discoveries on Frontios, indicating a need for secrecy, directly links to Tegan and Range later having a tense conversation about the ominous phrase 'Deaths Unaccountable' and the dangers of curiosity on such a beleaguered planet, echoing the same theme of dangerous secrets being kept from external authorities (Time Lords) who might intervene to expose darker truths kept hidden by Frontios's own leadership or inhabitants like Brazen."
