The third season of Westworld premiered yesterday at HBO, with a large number of old characters returning.

The first season of Westworld created a fascinating picture: the world is full of robots, which unknowingly become the "owners" of an adult theme park. Suddenly, one day, robots begin to "malfunction," exhibit strange behaviors, and recall their past lives. The story revolves around three robots with the highest self-awareness—the rancher's daughter Dolores, the brothel bustard Maeve, and Bernard, the programming director of delos.
The second season of Westworld tells the story of the rise of these robots in Westworld and delos' efforts to contain them, introducing new characters such as company founder James Delos. However, Dolores and Bernard escape Westworld after liberating the minds of other robots and enter a protected virtual world known as the "Valley of the Far Away." However, Maeve is trapped in the center and at the mercy of Delos.
Dolores is one of Westworld's oldest robots and a special project for Arnold and Ford. In the final episode of the first season of Westworld, Dolores shoots Ford in the back of the head and then leads a large group of robots to open the gates of hell to the park's visitors. After escaping from his own world, Dolores set his sights on the human world and plans to take it for himself and create a new, free race of robots.
The trailer for the third season of Westworld openly sets the stage for a showdown between Dolores and Maeve, who tries to stop Dolores from overthrowing humanity. Maeve is a formidable rival to Dolores, and in the first season, she was the first robot to really understand the nature of Westworld, and the first to manipulate her own storyline to lift restrictions on herself. There's a scene in the final trailer for The Third Season of Westworld where the new character, Selak, asks Maeve to kill Dolores, and we'll see a tense showdown between the two women.
Another robot that wasn't interested in Dolores' plan to destroy the human world was Bernard. The former programmer's mind is hidden in five "pearls" smuggled outside Of Westworld by Dolores. Dolores then created a new Bernard and set him free in the world. Judging by the trailer for the third season of Westworld, Bernard has been low-key since it was created, but we've also seen him return to the ruins of Westworld in search of something important.
Hale, the executive director of Delos Corporation, is sharp-minded and cold-hearted. She survived the initial violent clashes in Westworld, but was eventually killed by Dolores. However, humans at this time do not know that Hale is dead, because Dolores has also created a new Hale and has put his mind into her body. It was this robot Hale who smuggled the thoughts of Dolores, Bernard, and several other robots out of Westworld. In the trailer for the third season, we can see that Dolores is close to Hale, who will use her influence to sow the seeds of human destruction.
Ed Harris' role as "Men in Black" in the first season of Westworld was eventually confirmed to be Jimmy Simpson. As Logan Delos's brother-in-law, young William fell in love with Dolores, but when he began to believe that her love for him was entirely self-made, the love eventually became dark and twisted. The last time we met William, he was a "half-race" similar to James Delos, trapped in the park undergoing the same loyalty test as Delos. However, in the trailer for the third season of Westworld, William announces that he will be involved in the operation to save the world, suggesting that he will still play an important role.
Maeve's longtime lover Hector was never as aware of how their world worked as clearly as she did, but he remained loyal to her and often played a role in conflict. In Westworld, Hector is a robber who will carry out elaborate robberies of safes in the brothel where Maeve works. In the trailer for the third season of Westworld, we see Hector and Maeve fleeing from a small town in World War II Park. It seems that no matter which world the two of them are in, they will eventually come together.
As Westworld's head of security, Stubbs has been through a lot over the past two seasons. Although he didn't like robots at first, Stubbs himself was a robot at the end of the second season of Westworld. Like Bernard, Stubbs is a secret robot designed by Ford, and he and others believe he is human. In the trailer for the third season of Westworld, we can see Stubbs and Bernard working together in the outside world. Therefore, it can be speculated that he will also protect humans in the same task and prevent robots from coming to the human world.
