Doctor and Romana map Meglos’s plan

With the Doctor freed and Meglos’s escape confirmed, Romana and the Doctor urgently piece together his motive. Romana’s deduction about the Screens of Zolfa-Thura crystallizes the location and method of Meglos’s endgame, revealing the deadly alliance between the Dodecahedron and the planetary defenses. This briefing transforms vague threats into a concrete target, uniting them in shared purpose against a plan that could reduce an entire planet to ash.

Narrative Connections

How this event relates to others in the story

What this causes 1
Causal

"The Doctor's deduction in Act 1 that Meglos intends to use the Dodecahedron with the Screens of Zolfa-Thura directly motivates his later infiltration and sabotage of Meglos's control complex in the laboratory. The Doctor's understanding of the Dodecahedron's operational framework (Screens + control complex) sets up his later actions in Meglos's lab."
