Westworld: Ranking Every Main Character From Worst To Best

The ill-fated head of Quality Assurance was the chief Delos operative inside the park. Aside from her daily duties of upholding standards and safety regulations inside Westworld, Theresa was also Robert Ford's point of contact with the Delos board and attempted to slowly wind him down into retirement wherever she could.

Before Charlotte arrived towards the end of the first season, Theresa was the only Delos representative on the show and she was far more humane than her successor. Her genuine affections for Bernard made her sympathetic and watching her hold her own against Ford was at the very least respectable.

Unfortunately, Theresa failed to outwit Westworld's resident ruler and she falls victim to her lover Bernard after Ford orders him to kill her. The reveal that Bernard was a host remains the best executed twist on the show and it is all the more impactful due to Theresa's murder. Her death is also significant as she has stayed deceased which can be rare on this show.
