another route to the TARDIS, the Doctor is separated from the others, who are arrested. With his attempt to escape now being broadcast as entertainment to all of Varos, he enters a corridor that appears in his mind as a desert, and due to its psychological effects, begins to die from thirst. By this time, Peri has been brought to the control centre in the company of the Governor, Sil and the other officers. They question Peri as she watches the Doctor's body being taken away to an acid bath for disposal.
