Frau Clovis was the Duke of Manhattan's personal assistant. When the hospital came under quarantine, she went looking for service. However, upon seeing several infected humans, she screamed in terror before activating the alarm and fleeing back to Ward 26. She was a very formal, uptight woman, and said she did not want to die in the New New York Hospital. When under attack by the new humans, she helped barricade the door. Frau Clovis tried to help the Tenth Doctor gather all the packs of vaccinations. She survived the events at the hospital. (TV: New Earth)
