Doctor shifts investigation to the Hydroponic Centre

The Doctor and Mel discover their critical evidence—the incriminating tape—has been removed from the control booth, frustrating their immediate case against Lasky. As Mel challenges assumptions about the killer’s identity, the Doctor pivots their strategy to the Hydroponic Centre, the epicenter of the cross-fertilization experiments and plant mutations. The urgency of the Vervoids’ genocidal intent against animal-kind forces an acceleration of the investigation, with Mel reassigned to trace the missing evidence while the Doctor moves directly toward the source of the threat. Every second wasted increases the danger to the entire ship. key_dialogue: [ DOCTOR: Just as he tried to remove you. MEL: He? Why not she? DOCTOR: Lasky? MEL: Or the stewardess, Janet. DOCTOR: Janet?

DOCTOR: Hydroponic Centre. There has to be a connection. ]
