The Doctor’s feigned cooperation masks his deeper sabotage plan while the Master’s claim that he may still prove useful hints at a dangerous gamble to exploit the Doctor’s brilliance. This moment pivots the Doctor’s role from reluctant captive to infiltrator under duress, setting up the final confrontation in the underwater base.
