This was originally scheduled to be episode 29 of the series but was brought forward when the earthquakes in Syria & Turkey made it inappropriate to transmit the planned episode Hell is Empty (2023). The series then took a week's hiatus.
This is a stand-alone story with no reference to any of the running plot lines. However, due to being broadcast out of sequence, the opening titles include Dr. Suni Bulsara, a character not yet introduced.
