The Doctor is taken to the Dalek base for interrogation and is put in the same cell as the recently captured Codal. The Doctor tries to use his sonic screwdriver to open the cell door, but to no avail. He and Codal then conceive of modifying the components of the TARDIS log to emit a radio frequency that will jam Dalek control impulses. Meanwhile, Jo is being cared for by the Spiridon who found her. His name is Wester, and he is one of a group of his people who are trying to fight back against the Daleks. He cures Jo of her fungal infection with a salve, and tells Jo that the Doctor and Codal have been captured and taken to the Dalek base. Jo is determined to try to free them, even though Wester says that if the Daleks use them for their experiments, they are better off dead.
