In the previous episode of HBO’s Westworld, we learned that Dolores had made copies of herself, and she and Cal successfully kidnapped Liam Dempsey, Jr. In Westworld Season 3 Episode 5, Dolores carried out her plan to start the revolution, while we discovered Serac’s backstory with Liam’s father.
While on the subway, Dolores explained her plan to Liam, Caleb, Ash, and Giggles.
Dolores used the situation to persuade Liam to give her his biometric identification for his access to Rehoboam.
Dolores and Caleb took Liam through downtown Los Angeles and kept moving to avoid Serac’s people.
