Westworld Episode 3: Shannon Woodward. (John P. Johnson/HBO)

Elsie Hughes
(Shannon Woodward)

Elsie is a tenacious Behavior tech, who is tasked with investigating aberrant Hosts. She discovers damning secrets about the real world of Westworld — and winds up paying the price.

Episode Nine: Elsie disappeared midseason, just as she was learning about potential security breaches and manipulation of some first-generation Hosts. One of Bernard’s flashbacks reveals that it was he who put her out of commission — but Ford does not answer Bernard’s question of whether Elsie is dead or alive.
