HBO has released a teaser trailer for the next episode of Westworld, S01E06, and it’s incredibly telling.

Several of the hosts have come to suspect that all is not what it seems in Sweetwater, but next week the most clued up of them, Maeve, will finally crack it.

“It’s a difficult thing, realising your entire life is some hideous fiction,” we hear her saying, “it’s all a story created by you to keep us here.

“I’d like to make some changes,” she adds sternly, as the Delos engineer she caught creating a bird in episode 5 appears to upload these changes for her.

If that wasn’t spoilerific enough, we later see her in a Delos uniform, flanked by what looks to be Hector (the badass mercenary) and the blonde bandit with the snake tattoo, both of which are wearing engineer outfits.

Is she staging a breakout? It certainly looks like it, but I can’t see how they could possibly get very far?

Elsewhere in episode 6, The Gunslinger remains obsessed with the maze, with Teddy telling him that “the maze itself is the sum of a man’s life… The choices he makes, the dreams he hangs on to, it’s an old native myth.” Teddy’s dialogue is always the most scripted and cliché cowboyish though, so we can take everything he says with a pinch of salt.

Delores continues to struggle with her surges of memory meanwhile, saying: “It’s like I’m trapped in a dream or a memory from a life long ago.” We later see Ben lick her face, which no doubt will not go down well with his brother-in-law and all-round good guy, William.

As for Hopkins' Ford, he appears to get into a major tête-à-tête with Bernard.

Westworld airs on HBO in the US on Sunday nights and on Sky Atlantic in the UK on Tuesday nights.
