The Westworld Season 1 finale is coming in less than a week, and fans can barely wait to see how the drama will end.

So far, the biggest revelation on The Well-Tempered Clavier episode was Arnold’s identity. This was disclosed when Robert Ford took the viewers to the moment of Bernard’s technological birth. It turned out that Bernard is not actually just a host. Bernard (Jeffrey Wright) is, in fact, Arnold.

However, Dolores killed Arnold at the end of the episode. Viewers are now wondering if Arnold forced Dolores to kill him. This may be disclosed on Sunday.

Meanwhile, more identity revelations are coming in the Westworld Season 1 finale.

Comicbook shared the official synopsis for the 90-minuteWestworld Season 1 finale. It reads: “Ford (Anthony Hopkins) unveils his bold new narrative, Dolores (Evan Rachel Wood) embraces her identity and Maeve (Thandie Newton) sets her plan in motion.”

This, however, further raised more questions, including Dolores’ identity. Who is she really? What is Maeve planning? Would the Mariposa Saloon and Brothel’s madame succeed? Does her plan involve Bernard? How about the Man in Black (Ed Harris)? Will the true identity of the black-suited gunslinger be revealed in the finale?

Show creators Jonathan Nolan and Lisa Joy assured fans that questions will be answered in the finale. The showrunners told Entertainment Weekly that they are not interested in spinning mysteries with no answers at the end.

Joy, however, teased that all of the questions viewers have will be resolved in the final episode, except for one – What happens next?  Westworld Season 2 is not expected until 2018. This means viewers have to wait for two years.

HBO programming president Casey Bloys earlier explained that they have yet to map out and write the scripts for Season 2. She also remained silent on whether or not the stars of Season 1 will come back for the second installment.
