Crew locks onto the P7E signal

Jackson directs Orfe to intercept the long-sought P7E signal, succeeding in the same moment the Argo's hull shudders against the signal's source. The Doctor identifies the transmission as the Quest, sensing its importance before Jackson confirms their precise location. The breakthrough tightens the crew's urgency as the planet's hidden dangers and forced laborers come into view, exposing the convergence of their mission with the enslaved Trogs' plight. One misjudged move could now doom them all. key_dialogue: [ JACKSON: Orfe, the signal. Tune in on the signal!
