Meanwhile, the Daleks have found a map dropped by one of the Thals showing the location of their explosive stash, and they send a patrol to detonate them. Jo, having tracked them there from the base, manages to reset the denotation timers on two of the units, but is knocked out by falling rocks while resetting the third. She comes to as a second patrol arrives, and hides with the reset units as the third destroys the patrol. Jo eventually encounters the Thals--and the Doctor, who is overjoyed to learn she wasn't killed earlier--and has an instant connection with Latep. They make their way to the Plain of Stones, a local landmark, to plan their next move. Codal reasons that the refrigeration chamber must be necessary to whatever plans the Daleks have on Spiridon. The impulsive Vaber urges an assault on the Dalek base to destroy the refrigeration device and confronts Taron over his cautious approach. He backs down, but then leaves the group in the middle of the night, taking the explosives with him. When Taron tells him what Vaber plans to do, the Doctor realizes this will wake the Dalek army from its hibernation.
