Trivia

 * In the commentary of this episode, Bradley James assumed that the cell where Gwen was held was located in Cardiff, but, in real point of view, we have to admit that this cell was in the same castle.
 * For Hengist's Fortress, the producer used the Caerphilly Castle.
 * The main filming location was the Great Hall.
