The episode aired in 2014, and was directed by Declan O'Dwyer. It was the fifth episode of season two so I had some catching up to do with regard characters. In the "previously on" section at the beginning of the programme we see Jason (Jack Donnelly) fall down a precipice in a necropolis with an enemy, Medea (Amy Manson, Being Human), and another apparent enemy Pasiphae (Sarah Parish) being shot with an arrow.
