Westworld has crossed its halfway mark in the 10-episode long Season 1 and this Sunday's episode of the science drama will see Anthony Hopkins' Dr Ford warning someone against trying to take control of the park from him.
The episode is titled The Adversary and the trailer sees Dr Fork talking to someone, saying: "I designed every part of this place. Did you really think I would let you take it from me?"
Who is at the receiving end of Dr Ford's threatening words will be revealed on Sunday, but there are quite a number of people who are working with their own agenda. For instance, the Man in Black and Teddy are trying to solve the puzzle of the maze, and Ed Harris' character has already declared himself a villain. Dolores, in the meantime, seems to be working towards destroying the park.
Last week's episode saw Dolores saying that Arnold wanted her to help him destroy the park, and she also revealed that she hasn't been in touch with Arnold for about three decades. But it seems to be a lie, as soon after Dr Ford finished questioning her, she spoke to someone, presumably Arnold, about hiding the truth from the co-founder.
Elsewhere in the episode, viewers will see Thandie Newton's Maeve, who has become aware of her past, waking up on the operating table and demanding a few changes from her creators. Maeve could be getting what she wants, as a few shots show her being followed by Westworld employees.
The official synopsis for The Adversary reads: "Lutz is charmed by Maeve; Elsie discovers evidence that could point to sabotage; the Man in Black and Teddy clash with a garrison."
Westworld airs Sundays on HBO. The episode can be watched online via HBO Now as well as HBO Go.
