They absolutely were impacted by the writers' strike, but at least for Silo, the source material is already done. I've read the books. I know what happens at the end of Silo. A lot of people do. Of course, they're adding a bunch of stuff, so everything I know is subject to change. But the end of season 2? That curve ball? I knew exactly where it was going. The part we didn't see? There is stuff from the end of the first book I was expecting us to get, but they cut us off to show the stuff from the second book, to whet our appetites. So I know how the next season is going to begin, because they are absolutely going to wrap up that story, because what comes next is so big. They aren't going to hold it off... I'd say at the latest, the end of the first episode.
