The first season of hit Apple TV+ sci-fi show Silo left things on quite the cliffhanger, with Rebecca Ferguson's Juliette venturing out of the titular underground shelter – and out of sight of those she left behind. Audiences have been waiting over a year to find out what happens next and finally that time has come, as Silo season 2 will be soon be arriving on our screens.
