It's the last story of season 7 already (although Sarah doesn't know it yet). More industrial locations, more UNIT action but love saves the day along with our attention span as Greg and Petra become our new favourite couple - in both universes...

If you're new to Who and want to watch along with us, Mark watched the official BBC DVD release of Inferno and Sarah watched on Britbox.
