Pictured: A scene from Sunday's episode of Westworld.HBO

Dolores is no longer interested in playing the damsel in distress, and this Sunday's episode of Westworld will see her teaming up with William to find out the truth about her existence.

The promo for the next episode shows Dolores realising that there is a whole different world outside, and she seems curious when William talks about the real world. Also, some viewers believe that Dolores has already unlocked or has been close to unlocking the maze in the past, thanks to certain hints from the promo for Contrapasso.

Here's what Reddit user pazyrk has to say: "Dolores is out of her loop in the 'present' and she's remembering being out of her loop another time, the time she was with William. The fact that she sees the girl at the well briefly and them the girl has vanished indicates that a visit to Las Mudas happened more than one time and the memories are coming back."

According to the official synopsis for Sunday's episode, viewers will see Dolores (Evan Rachel Wood), William (Jimmi Simpson) and Logan (Ben Barnes) reaching the town of Pariah and they will soon be recruited for a dangerous mission. Meanwhile, Ed Harris' The Man in Black will meet an unlikely ally in his search to unlock the maze. It remains to be seen who the ally is, but the promo hints at a tense scene between Dr Ford, the Man in Black and Teddy.

Westworld airs Sundays on HBO. The episode can be watched online via HBO Go and HBO Now. New episodes of Westworld will also be available on Star World Premiere HD on Tuesdays at 10 pm IST.
