Sister (The Peterloo Massacre)
From Tardis Wiki, the free Doctor Who reference
One Sister helped tend to the protesters wounded during the Peterloo Massacre. Nyssa, Tegan Jovanka, and William Hurley talked with the Sister after they brought Cathy Roberts to the infirmary. She told Nyssa and Tegan that the nuns would be taking the names of all the injured they cared for and then - in return for monetary compensation - they would give all the names to the Manchester yeomanry so that the protesters could be punished.
The Sister later brought Cathy's father to see Cathy while she was in the infirmary. (AUDIO: The Peterloo massacre)
