Meanwhile, Penley has found the Doctor and taken him to Jamie. He determines that Jamie has temporary paralysis and heads to the Martian craft. He offers himself as an envoy, leaving his communicator active so Clent can hear, and is allowed to enter the airlock. With the glacier threatening to crush the spacecraft, the Doctor has Victoria released to him. Before Varga takes the communicator, the Doctor relays the message that Clent needs to use the Ioniser, regardless of consequences. The Doctor is marched to the core of the spacecraft, where he spots an ion propulsion system. Varga decides to attack the base and orders his Warriors to prepare a sonic cannon.
