Westworld Season 1 answered a great many mysteries of the title park’s past, but in the absence of a thirty-year twist, Season 2 may go even deeper. Stars preview that Westworld will delve not only into the park’s history, but also its true purpose when the series returns in 2018.

Star Evan Rachel Wood offered Variety a few comments on Season 2 from the Creative Arts Emmys; in particular that Dolores herself is “quite a different beast” this time around. And where Season 1 gave us a little insight into Arnold and Ford’s early days with the park, Season 2 will delve deeper into its origins and mysterious purpose:

I think you’ll be seeing a lot more of what Westworld is capable of, a little more the backstory of how it came to be, why it’s there. There’s a lot of pieces being filled in.

The “why” is of particular interest, as a great deal of Season 1 saw the Delos board attempting to smuggle out secrets of the park’s “proprietary technology” for an unseen world. Robert Ford and Bernard also seemed to have some resigned awareness of burgeoning A.I. in the Hosts, either of which could suggest some deeper purpose behind the park than simply amusing well-to-do tourists.

Elsewhere of Westworld Season 2, the spring 2018 “Journey Into Night” is expected to answer practical questions about the park, potentially even a date for the show’s setting. Ed Harris will be back to play Season 2 on extreme mode (no guarantee for William), while Talulah Riley and Louis Herthum have also been upped to series regular. We’ll also finally get answers on the mysterious “SW” park, and hopefully learn what became of poor Elsie and Stubbs (the latter of whom might be visible in the first trailer).

New additions include Leftovers alum Katja Herbers and Fargo big bad Zahn McClarnon, along with Neil Jackson and American Gods star Jonathan Tucker, Vikings favorite Gustaf Skarsgard, Tyrant alum Fares Fares and actress Betty Gabriel.

We’ll see what other Westworld Season 2 details or footage emerge soon, so stay tuned.
