It was announced on April 7, 2012 that the running order of the series would be altered, with "Domestic" being aired in place of "And Then I Fell In Love", for unknown reasons. However, it was later revealed that the story was removed from the broadcast rota as its storyline mirrored the "Rochdale Sex Crimes" case that was being focused on by the media at that time, and due to the trial still pending, it was suggested that the episode be pulled so that it does not have any bearing on the outcome of the trial. It was later suspected that the episode would be aired on 7 May 2012. However, a repeat of the Series 14 episode 'Bloodlines' aired in its place. The broadcast in the United Kingdom was delayed until 19 August 2012 with the Australian Broadcasting Corporation first to broadcast the episodes on August 3 and 10 respectively.
