US President Felix Mather's wife was First Lady of the United States in the 21st century.
When the Eighth Doctor referred to Mather by his first name, Malady Chang winced upon hearing and thought of how even the First Lady called her husband "Mr President" in public. (PROSE: Trading Futures [+]Loading...["Trading Futures (novel)"])
Behind the scenes[[edit] | [edit source]]
The home video Ex-President [+]Loading...["Ex-President (home video)"], released in 2022, would depict history being rewritten so that Felix Mather's presidency is replaced by that of Barack Obama's. Presumably, Mather's First Lady would meet the same fate, though her character is not elaborated on.
