Doctor compelled to condemn Leela

The Doctor’s unraveling reaches a breaking point as Meeker’s relentless demands exploit his growing corruption. Repeating the entity’s line about the purpose being all important, Meeker torments the Doctor into submission, twisting his fear and compromised will into complicity. The Doctor’s agonized capitulation culminates in a direct order for Meeker to kill Leela, transforming him from an ally into an instrument of the alien nucleus. This marks the moment the Doctor is fully yielded to the infection, forfeiting his moral agency and becoming a dire threat to the one person who still fights against the spreading corruption. key_dialogue: [ MEKER: Think of the purpose.

The nucleus does not wish to be harmed. I shall destroy her. DOCTOR: Yes. Kill her. Kill her. ]
