After more than a year off the air, Westworld will return to HBO this spring. Showrunners Jonathan Nolan and Lisa Joy have been tight-lipped about what to expect from the show's long-awaited sophomore season, but here's everything we know so far.

The show will return with 10 new episodes this spring: HBO revealed the show's premiere date during the Super Bowl; the 10-episode second season will debut Sunday, April 22 at 9/8c. Set your DVRs.

There will be a time jump at the start of Season 2: Nolan confirmed to Entertainment Weekly last year that the series would not pick up immediately after the events of the Season 1 finale, which saw Dolores (Evan Rachel Wood) lead a rebellion against the park's guests and board members after achieving full consciousness and Maeve (Thandie Newton) abandon her attempt to escape to search for the daughter she had in a previous storyline. However, Joy did did note that fans are "definitely going to see the aftermath and the effects of what happened."

The second season will explore the culmination of Ford's new narrative: In an interview following the Season 1 finale, Nolan said that chaos would be a theme of the second season: "Ford has set in motion what he thinks is a plan. The nature of that plan is something we explore in the second season — what his intentions are: Are they to let Dolores and the other hosts escape? Are they simply to teach the human guests a lesson?"

We will be exploring other parks too: In the Michael Crichton film upon which the series is based, there were two other parks: Roman World and Medieval World. While it's unclear if the same two parks exist within the show's narrative (a website for Delos Destinations advertises six parks that are active or in development, with only the Westworld site being accessible), fans have long suspected the show would introduce a separate world known as Samurai World ever since Maeve first saw hosts dressed in armor similar to that of feudal Japan and brandishing swords during the show's first season. Evidence of the park has only grown since then: Last summer, popular toy maker Funko released a new figure during San Diego Comic-Con that was dressed in samurai gear. His name was Musashi. Now, Hiroyuki Sanada (Helix, Lost) has joined the show for multiple episodes as a character with that name.

Like the Cylons, the hosts have a plan: In the Super Bowl teaser — a full trailer will be released at a later date — Dolores reveals a master plan in a voice-over accompanied by footage mostly taken from the new season. "This beautiful world — we built this world together, a world where dreams come true, a world where you can be free," she says. "But this world is a lie. This world deserves to die, because this is your world. We've lived by your rules long enough. We can save this world. We can burn it to the ground, and from the ashes, build a new world: our world." OK, so it's not so much a plan as a threat, but it turns out the Cylons didn't really have a plan either so...

Westworld: Tessa Thompson Reveals Who's in Charge in Season 2

A number of familiar faces will be returning: Although there's no word on whether or not we'll see more of Anthony Hopkins as Dr. Ford — he was seemingly killed by Dolores in the finale, but that doesn't necessarily mean anything — there are a number of cast members confirmed to be returning for Season 2. Wood, Newton, James Marsden (Teddy), Jeffrey Wright (Bernard/Arnold), Ed Harris (the Man in Black), Tessa Thompson (Charlotte), Luke Hemsworth (Stubbs) and Simon Quarterman (Lee) will all be back.

If you were one of the fans wondering what happened to Shannon Woodward's Elsie, who was absent from the second half of the first season after she was seen being choked by Bernard, HBO has been dropping hints about her survival for a while now. So, look for her to hopefully return in Season 2.

Meanwhile, HBO has announced Louis Herthum (Peter Abernathy) and Talulah Riley (Angela, the blonde host who first welcomed William to the park) have been promoted and are now series regulars. And don't be surprised if you see more of Clifton Collins Jr. (Lawrence/El Lazo), Ingrid Bolsø Berdal (Armistice), Rodrigo Santoro (Hector) and Angela Sarafyan (Clementine).

William and Logan will be back too: Because William appears in a separate timeline in the past, it wasn't immediately clear if Jimmi Simpson, who played William's younger self, would be returning to the show in any capacity. However, Simpson has confirmed he'll be returning as the more innocent version of Harris' Man in Black, though we don't yet know how. Also confirmed to return is Ben Barnes as the debauched Logan, the man who first introduced William to the park, but the Punisher actor wouldn't say much else about his return. Still, he makes a brief appearance in the Super Bowl teaser: he's attending a very swanky party, but all the hosts have frozen around him.

We'll also meet a number of new characters: New series regulars for Season 2 include Vikings' star Gustaf Skarsgard as the white-collared Karl Strand; Katja Herbers (Manhattan, The Leftovers) as seasoned park guest Grace, who visits during the park's darkest hour; and Tyrant star Fares Fares as tech expert Antoine Costa.

Elsewhere, Neil Jackson (Sleepy Hollow) and Jonathan Tucker (Kingdom, Justified) will be joining Season 2 in recurring roles. Jackson will play a man named Nicholas who finds himself in unfamiliar territory, while Tucker will play a military officer named Major Craddock. Zahn McClarnon (Fargo) has also joined the show in a mystery role, while Peter Mullan (Top of the Lake, Quarry) will be taking on the role of James Delos, the founder of the the corporation that ran the park.

Westworld returns for Season 2 on Sunday, April 22 at 9/8c on HBO.
