The Stray
Elsie and her colleague Ashley Stubbs head into the hills in pursuit of a missing host.

Chestnut
A pair of guests, first-timer William and repeat visitor Logan, arrive at Westworld with different expectations and agendas. Bernard and Quality Assurance head Theresa Cullen debate whether a recent host anomaly is contagious. Meanwhile, behavior engineer Elsie Hughes tweaks the emotions of Maeve, a madam in Sweetwater's brothel, in order to avoid a recall. Cocky programmer Lee Sizemore pitches his latest narrative to the team, but Dr. Ford has other ideas. The Man in Black conscripts a condemned man, Lawrence, to help him uncover Westworld's deepest secrets.
The Original
As another day of fantasy plays out in Westworld – a vast, remote park where guests pay top dollar to share wild-west adventures with android "hosts" -, top programmer Bernard Lowe alerts park founder Dr. Robert Ford about incidents of aberrant behavior cropping up in some recently re-coded hosts. Meanwhile, in the Westworld town of Sweetwater, a rancher's daughter named Dolores encounters a gunslinger named Teddy in the street – but their predictable narrative is upended by the appearance of a ruthless Man in Black and, later, by a supporting host's unscripted encounter with an artifact of the outside world.
