Jo Grant's Distress Radio

Jo Grant’s distress radio serves as the critical catalyst for the event, its urgent transmission cutting through the diplomatic tension in the Axos Main Chamber. The radio’s static-laced voice—unseen but heard—immediately commands the Doctor and Brigadier’s attention, overriding all other priorities. Its role is purely functional: to convey Jo’s peril and trigger an instinctive response. The radio’s presence, though brief, is pivotal, as it exposes the fragility of the negotiations and forces the Doctor and Brigadier to abandon their diplomatic efforts in favor of immediate action. Its impact is amplified by its brevity; the lack of detail about Jo’s situation heightens the urgency and leaves the nature of the threat open to interpretation.
