"Can't we say that?"That sentence from Westworld co-creator/co-showrunner Lisa Joy sums up the information revealed about Season 2 of Westworld at the show's PaleyFest panel on Saturday. She was joined by her fellow showrunner (and husband) Jonathan Nolan, executive producer Roberto Patino, and cast members on stage. Joy was going to share a few tidbits -- the answer above is in reply to a question about when filming for Season 2 will begin -- but Nolan wanted to keep everything under wraps for now. "Isn't it more fun to guess?" he said.

After joking about the "Reddit factor" that led to some core reveals on the show being figured out and widely shared online very early in the season (he'd love if fans kept speculation and commentary on the show's mysteries you've solved offline and not on blogs, thank you very much), Nolan said that unlike Season 1, they are writing all the Season 2 scripts before they begin shooting. "It was a real lesson for us in the first season. When they say it's not TV, it's HBO, they're not kidding. It's a 10-hour movie we're making here. We're writing right now. We're terribly excited about what we're writing." He joked, "Reddit's already figured out the third episode twist, so we're changing that one."Patino gave a vague clue about the future, "There will be a story, and it will f**k with the metaphysical at some point." As far as going to other worlds, like maybe the Samurai World or Shogun World teased in the Season 1 finale? Nolan said, with a laugh, "That would be cool, wouldn't it?" Yes, it would be cool.And the only other Season 2 hint, aside from Ed Harris requesting he doesn't want to be naked or wear a samurai suit in the next installment, focuses on the music. "I can tell you a hint about one of the songs," Joy said, "At home, we have a little girl, so we spend a lot of time watching children's movies. One of them has proven to be musically incredibly inspiring. So there may be a strange shout-out to a very innocent and joyful song that we will and take and co-opt and make dark, just to traumatize our daughter."While the question and answer question session didn't give away the Season 2 farm, Nolan did answer a lingering and important question from the Season 1 finale. Maeve seemingly abandoned her escape narrative to remain on site and search for her daughter, but given all the manipulation going on to the Hosts, it wasn't 100% clear if her choice was a result of additional programming or truly her own decision. Turns out it's the latter. Nolan said, "If you look at her performance in that moment, that is really the first decision she's ever made. For me, it's a very emotional moment in the episode because you see her free will."Westworld will return to HBO in 2018.
