The Hosts are, what we assume, of alien origin. Will we learn more about when they first arrived and what they want?
Yeah, absolutely. Those mysteries are not what the show’s about. InLost, the mystery of the island and why these characters were there was the central mystery of the show. Those mysteries will be answered. They’re not really what’s at stake. What’s at stake is can this family survive in a world that’s been completely upended?
Will we ever get to meet the Hosts?
Yes. Again, it’s not a show about us versus the aliens. We feel like that show’s already been done. Very intentionally,[co-creator Ryan Condal] and I have focused our storytelling on the conflicts that arise when humans are empowered to subjugate other humans.
