Blake's 7 4.1: Rescue Season Four, the season they didn’t expect to make. Which means there’s a certain amount of getting up to speed required in order for “status quo” stories to be told. If they choose to go that route. There’s no Liberator anymore as a starting point for stories; a situation the show hasn’t found itself in since Space Fall . So where do they go from here? Behind the scenes there’s no David Maloney either. Nor Terry Nation (I’d say that by this point that’s slightly less of an issue, but his three scripts for Season Three were among his best).
