K9 disables pressure valve to enable rescue

K9 emerges from the ventilation shaft having disabled the pressure valve, collapsing the Company’s control over the water pumps and halting their lethal machinery. The rebels coordinate under Mandrell’s command to reverse the flow, buying the Doctor critical time. With the clock ticking on Leela’s execution and the Exchange room’s temperature dangerously high, the Doctor prepares to infiltrate the heart of the Company’s power matrix. This moment cements K9’s role as an indispensable ally and demonstrates the rebels’ fragile unity under desperate circumstances.
