Patient One was a patient at Hawthorne. His existence there was apparently secret. After Patient Zero's death and the thwarting of Dr Colin Dove's plan at perihelion, Peter Russell had a strange reaction to holding a knife and seemed to have a connection to Patient One, who laughed menacingly and sang "Daisy Bell" just as Zero and Russell had whilst possessed by the reservoir of evil.

Behind the scenes Edit
Patient One was played by Peter Davison.
