HBO has released the trailer for the final episode of Westworld season 2, with William declaring: "This is the end. Nothing else is in the way now."
It opens with the familiar phrase "freeze all motor functions", but uttered by the unfamiliar voice of Dolores.
A fast-paced montage follows that teases a number of intriguing visuals, as we glimpse James Delos in the labs, Dolores and Bernard standing before what looks to be a vast archive or library and later in Delos' fidelity test apartment, plus Logan is seen through flashback next to a pool and leading Dolores and Bernard around.
Most curiously, we get a couple of shots with the world appearing to have a crack in it, Clementine slowly advancing towards it on horseback.
Westworld's plot has been even more labyrinthine in season 2 than in season 1, and has an awful lot to answer in its season climax.
Entitled 'The Passenger', the feature-length finale hits HBO in the US and Sky Atlantic and NOW TV in the UK on Sunday night.
