The Deputy led a Caretaker raid on the Fountain of Happiness Square in an attempt to cleanse it of Kangs. He managed to capture the Seventh Doctor and took him to the Chief Caretaker. After the Doctor was sentenced to death, the Deputy was tasked with guarding him. As his last request, the Doctor asked to see the rulebook by which the Caretakers governed their work. The Deputy granted this request and the Doctor fabricated several rules that the Deputy, and his fellow guards, then followed. These were to walk several paces from the prisoner, close their eyes and put their hand on their head. The Doctor then took the Deputy's key card and escaped.
