Evan Rachel Wood as Dolores Abernathy in a still from Westworld.HBO

Westworld will air its Season 1 finale on December 4, and it is expected to reveal the true identity of Wyatt, the main villain in Teddy's backstory. Watch the 90-minute-long finale titled The Bicameral Mind live this Sunday on HBO.

The official synopsis for the finale does not reveal much about the plot. It just states that Ford unveils his bold new narrative and Dolores embraces her identity. But the internet is flooded with theories on what would happen in the finale, and one popular belief is that Dolores will realise she is Wyatt, the same person Teddy has been hunting.

Episode 9 of Westworld made it clear that there's a connection between Teddy's memory of the villain and that of Dolores's memory of the massacre that happened in the City Swallowed by Sand. In Teddy's recollection of events, Wyatt is responsible for killing the general, and theories indicate that Teddy is actually thinking about the time Dolores killed Arnold, who is one of the creators of the hosts.

Meanwhile, Evan Rachel Wood may have already revealed Dolores and Wyatt are the same person, with a collage on her Instagram page featuring Alice in Wonderland, the Terminator and Kurt Russell. Westworld viewers have already seen the first two avatars of Dolores, and the third photo is the most telling as it is a shot from the movie Tombstone where Russell plays the character Wyatt Earp.

"#DoloresAbernathy in 3 fictional characters. #Westworld," she captioned the image.

Westworld Season 1 finale will air this Sunday on HBO and Tuesday on Star World Premiere HD. The episode can also be watched via HBO Go and HBO Now. The finale is expected to take viewers on a roller coaster ride.
