Doctor confirms Tegan bears Mara mark

Nyssa confronts the Doctor in the marketplace with the disturbing evidence of Tegan’s possession. She reveals the erratic behavior she witnessed and delivers the anti-dream device retrieved from their previous experiments. The Doctor examines the device and immediately interrogates Nyssa about the physical mark on Tegan’s arm—the unmistakable signature of the Mara’s influence. Realizing the immediate danger, they abandon further investigation in the crowd and rush to assess the situation in private, where the Doctor can properly examine Tegan without interruption. key_dialogue: [ DOCTOR: Nyssa! NYSSA: Doctor. NYSSA: She was behaving very oddly. DOCTOR: Was she marked? DOCTOR: On her arm. The mark of the snake. DOCTOR: It must be the Mara. Come on. ]
