Hidden Facial Image in Nestene Daffodil Programming
The Doctor and Jo Grant peer at this decoded visual from the Nestene daffodil's programming on a UNIT laboratory screen. It displays a partial human face—nose and mouth only—that reveals the radio trigger for daffodil activation. Jo's accidental radio signal sets off a nearby daffodil, spraying her with plastic film; the Doctor rips it away just in time. Benton, Yates, and the Brigadier witness the chaos as the image sparks the Doctor's deduction.
