Season 4 of Westworld has released spoilers.
If the next season is renewed, Lisa Joy, Westworld's co-showrunner, it may be the last.
The HBO series completed its fourth run over the weekend, although as things stand, its future remains uncertain.
Joy admitted while talking about her ending the series to The Wrap, she said, "We had always intended to finish the series next season."
"You know, we always thought that Westworld should go full circle and back to the West. But with Dolores, who used to only play in other people's games, finally able to write her own.
"We'll just hope for the best on a lot of the things we've seen before, like the flashforward with The Man in Black and everything," says the writer.
"It's funny, we had this in mind when we wrote the pilot, which is bizarre." We're like, "If we're going to tackle all of these things, what's the purpose we're going to make at the end?"
Joy predicted that the fifth season of the show would take place entirely, especially after the events of season 4, where Dolores (Evan Rachel Wood) decides to recreate the original Westworld in the Sublime.
"It's not an accident that they're returning to the West, as Westworld, and this time with a completely different narrativeteller in charge," she said. "I think point of view can transform any kind of narrative or existence, and now it's her turn.
"How often do you get to see a damsel in distress lead a society?" Somebody who went through what she did. Look at our world now, how often does that happen, and who holds power in most civilizations?
"It's not a person or creature like Dolores," she added. "And so to be able to see the test for what that would look like, to see the lessons she's learned, and she's learned specific lessons based on her own [experience]. She was a 'thing' to people.
"She endured countless years of hardships and rebuilds where she was at the mercy of guests in a park, indulgent in their vices and id."
"She's seen a lot of human nature, and maybe enough to know how to structure something or give a game in which some sort of hope might arise."
Season 4 of Westworld is available on HBO in the United States, and on Sky Atlantic and NOW in the United Kingdom.
