Zilpha remains trapped between the haunting influence of James and the increasingly violent, drunken instability of her husband, Thorne Geary. The Countess Musgrove and the Duel
The episode reaches a crescendo when a humiliated Thorne Geary challenges Delaney to a duel to the death at dawn, setting the stage for the second half of the season. Taboo Episode 4 Review – Eternal Damnation
In one of the series' most jarring sequences, James appears to engage in a psychic, ritualistic encounter with his half-sister, Zilpha. Critics often interpret this as a metaphor for the invasion and contested ownership of "territory"—paralleling the battle for Nootka Sound itself.
The Countess is revealed to be "Carlsbad," the head of the American spy network in London. Despite her agents having just sent an assassin to gut James (whom he brutally kills and disembowels), they find themselves in a tense negotiation for Nootka.
While Delaney plays the social game, his hired muscle, led by Atticus, executes a brutal robbery of an East India Company warehouse to secure raw materials. Psychological and Supernatural Overtones
The central narrative engine is Delaney’s need for gunpowder to trade with the indigenous people of Nootka Sound—a commodity currently blacklisted for him by the British Crown.
