S13E3 · Terror of the Zygons Part 3

Doctor warns about alien threat ignored

The Doctor and his companions present urgent evidence of alien infiltration to Duke Forgill, who dismisses their claims as absurd fantasy despite clear signs of the threat. As the Brigadier receives a critical call about the Skarasen’s violent behavior, the Doctor speculates the Zygons’ recent strategy change may have triggered the creature’s aggression. Forgill’s stubborn skepticism exposes a dangerous gap between recognized threats and hidden reality, while the Doctor’s deduction hints at the broader scope of the invasion. Sarah’s exclusion from active pursuit frustrates her but directs her toward vital research, setting up her uncovering of the Zygon infiltration in Forgill himself. key_dialogue: [ FORGILL: Half these books are devoted to the subject of the monster. There've been reported sightings since the Middle Ages. Now you're saying that aliens have been living under the loch for centuries? DOCTOR: Yes, I'm saying exactly that. DOCTOR: Well, perhaps not in itself, maybe, but their plans may have changed recently. Who knows? ]
