Barin and Zarkov enter the control room to stop the lightning field, encountering Kala who refuses to deactivate it. She attempts to kill Zarkov, but Barin shoots and kills her. Without Kala they are unable to deactivate the field from that control room. Barin tells Zarkov to hold the fort while he heads to Sector Alpha 9. Zarkov keeps trying, but is unable to deactivate the shield.
