Co-creator Lisa Joy calls is a "repiloting." Her Husband and fellow co-creator Jonathan Nolan says it's a "radical shift." "What's compelling and appealing about these characters is that they're not human," says Nolan. "As we said in the show, humans are bound by the same loops the hosts are, in some ways even smaller. You couldn't expect human characters to withstand and survive the kind of story that we're telling. The hosts have a different version of mortality, a different outlook. I think clearly with Dolores, as she's laid out, there is a longer view here, a larger set of goals. They're existential. They span eons. And that's a fascinating level of story to engage in."
