The Power of the Thirteenth Doctor

Father Brown 13.9 is called The Power of Suggestion and curiously enough The Power of the Doctor, also having Power in its name, could be thought of NuWho’s own 13.9 as it is the third episode that came after NuWho’s season 13 and before season 14 came about.

Not only that but both Power episodes featured a Thirteenth Doctor actress. The Power of the Doctor is Jodie Whittaker’s swansong as the Thirteenth Doctor and the similarly named Father Brown episode guest starred Debra Stephenson who voiced the Thirteenth Doctor in the webcast Doctors Assemble.
