He rescued The Doctor and Petra from the troll in a helicopter. Petra sees Hamilton Bryant aboard and the minister orders the helicopter to take off. He then bombed the Sphereosis, falsely believing that bombs would kill it.
Stubbornly refusing to believe that the troll was actually Karl Bearing, despite the mounting evidence, he sabotaged the relay link to the outside world, locked the Doctor in a room with the Sphereosis and tried to force Katy Bearing to go under the bridge. Petra tried to save her, but Bryant ordered Chavez to shoot her. After a face-off, Petra stood down, and Bryant ordered Chavez to put his gun away. Petra ran to save Katy, but was shot.
