The lead actress of HBO's "Westworld" will get you primed for the Season 1 finale without giving away any spoilers. (OK, maybe one.)

[Editor’s Note: spoilers below, through Episode 9 of “Westworld”]

There’s not much Evan Rachel Wood can say about the “Westworld” finale.

“It’s so hard,” Wood said about keeping the show’s many secrets. “I’m excited about being able to say things out loud again.”

Despite one more week of closely guarded twists, what Wood could tell IndieWire is enough to raise even the most excited fan’s expectations. After nine episodes of surprises — starting with Wood’s character, Dolores, killing a pesky fly in the show’s premiere — Wood sums up Episode 10, “The Bicameral Mind,” in one word: “Wow.”

IndieWire spoke with Wood about what to expect on Sunday, how she shared her own fan theories with co-stars during production, and what little she knows about Season 2.

Congratulations on the Season 2 renewal. We all kind of knew it was coming, but it’s such a relief to get the official word.

No one’s more excited than me to come back — I guarantee it! That’s the only clue I’m going to give you. [laughs]

Oh good. Dolores isn’t gone. That would be devastating.

[laughs]

So do you know anything about what’s coming in Season 2?

I know a little about what’s coming in Season 2. I know how our ending for Season 1 will segue into Season 2 and… wow. [laughs] That’s all I can say. I think it was always that Season 1 was going to be this backstory and set up — getting to know the park and characters. I think Season 2 is really going to be warp speed. The show might really start in Season 2.

I heard that out of all your past roles, Dolores is your favorite character. Was there a particular scene or moment that made her stand out?

The moment that always sticks out for me is in Episode 5, when we see her take out five Confederatos that are holding Jimmi Simpson’s character hostage. They grab him and pin him up against a wall, and he yells, “Dolores, run!” The first take we did, I ran — I’m not supposed to run. [laughs] Everyone was kind of looking around, confused, and then I slowly crept back onto set and they asked, “What happened?” And I said, “I’m so used to running. I’ve never been asked to stay and save the day.” I got a little teary-eyed and a couple of women on the set got a little teary-eyed, and I thought, “Wow. This character is really important.”

I think as the show progresses, she’s transcending her role as the damsel, as the woman who’s supposed to stay at home. She’s overriding her programming and her conditioning. Every episode, she’s opening up more and more. The only thing I can say about Episode 10 is I feel like a lot of people are going to get up on their seats and clap. [laughs] There are certain things that we’ll see which made that character so important to me and will make her so important to a lot of people.

Do you read fan theories? Do you go online to see what people are talking about?

Oh, no. I’m aware of some of them, and my favorites are when people will send me a dissertation on a theory they have, and they’re so sure [they’re right]. They’re like, “Just remember: I said it first!” And they couldn’t be more wrong. [laughs] That stuff cracks me up.

And since we didn’t have the scripts when we were filming, I was one of those people [coming up with theories]. It took us about a year to do Season 1, and we went on a hiatus right after we found out about Jeffrey’s character. So we all had to wait — for months! — to find out what was going to happen next and to find out how the series was going to end.

It was torturous, but in the meantime all we did was spout theories. We had a big text chain going around with Shannon Woodward, Jeffrey Wright and Jimmi Simpson, and poor Jimmi. He was my rock during the whole first season, and he would just get an earful every day from me about the thousands of theories that I had. Most of them were wrong, but I did guess three. I did not see Jeffrey’s [twist] coming. I will say that. That was a surprise. I ran onto set the next day and wagged my finger in his face, saying, “This whole time! This whole time!”

Were the three that you guessed ones that have happened yet?

They haven’t happened yet. There’s a lot of mysteries surrounding a few of the characters that are still unanswered — these looming characters of Arnold and Wyatt. I dove into that and maybe figured it out beforehand.

That’s pretty impressive.

I should say, certain things you just won’t be able to guess. They need to be explained to you. You’ll never be able to really connect the dots. You can have a feeling, but until it’s really laid out, it’s just not going to make sense to you. So, you know, keep trying. [laughs]

The Season 1 finale of “Westworld” airs Sunday, December 4 at 9 p.m. ET on HBO.
