Evan Rachel Wood's Westworld character, Dolores Abernathy, had a big transformation in the first season of the HBO show, leaving the actress wondering what the host is capable of come season two.

ET has an exclusive first look at a featurette of Wood talking about Dolores' story arch on Westworld, and what it was like to take on such a complex role.

For those who haven't seen the hit TV series, Westworld is the name of a technologically advanced Wild West-themed amusement park that is populated by androids that are referred to as "hosts." The park caters to high-paying visitors called "guests," who indulge in whatever they wish within the park, without fear of retaliation from the hosts -- or so they think.

Wood portrays the oldest host in Westworld, and seems to be different from all the others. "We don't really know how aware these hosts are," the 29-year-old actress -- who was nominated for a Golden Globe for her role -- explains. "This girl, who has been so beaten down and been the damsel her whole life, starts to change her story. She starts going against her programming."

Wood admits, "We still aren't quite sure how deep Delores goes."

ET recently spoke with Wood's co-star, James Marsden, about the show's shocking twists and turns, and he admitted that even those on set had a hard time predicting the storylines. "We never knew! The actors never really knew what the hell was going on," he shared. "We would get the scripts sometimes four or five days before we'd shoot the next episode, so we didn't know the end game either."

On March 6, the first season of Westworld, along with several special features and deleted scenes, will be available on digital HD, including Amazon Video, CinemaNow, iTunes, PlayStation, Vudu, Xbox and more.
