"The collapse of Company control on Terminus (with Nyssa’s revelation and Valgard’s disarming) creates a narrative vacuum filled by the Doctor’s urgency in Terminus. This urgency carries forward as the Doctor immediately detects life-altering power misuse (energy theft) upon returning to the TARDIS, mirroring the systemic corruption uncovered in Terminus's operations."

"Nyssa’s decision to stay and her role in freeing the Vanir (Terminus) establishes the Doctor’s preoccupation with liberation and moral responsibility, which directly carries over to his immediate concern with ‘power draining’ (TARDIS energy theft) in Enlightenment. His leadership in securing others' freedom mirrors his later focus on preventing the misuse of power."

"Turlough's resistance to the Black Guardian's lethal command in Terminus (refusing to murder the Doctor despite manipulation) directly informs his detached yet watchful behavior in Enlightenment Part 1. His earlier defiance under duress mirrors his guarded curiosity about the Doctor’s actions and the White Guardian’s warning, suggesting a burgeoning—if reluctant—alignment with the Doctor."

"Both Terminus and Enlightenment hinge on the misuse and manipulation of power: in Terminus, the Company abuses power to control others via Lazar disease; in Enlightenment, the Black Guardian tries to manipulate the Doctor and reality itself through energy/power theft. The Doctor’s quest to thwart this misuse is a thematic throughline."
