Doctor Who showrunner Russell T Davies says that the mysterious Mrs Flood will be in every episode of season 2, as "spectacular answers" are finally delivered
Look, I'm optimistic about the new season until proven wrong, but even I wince at that kind of hollow hyperbole. The episode previews have been promising enough that I'll be happy if the season arc is cohesive and sticks the landing.
Unfortunately, I also know that it's when RTD aims for "spectacular" he tends to lose sight of the basics.
