The sister was tough on staff and patients alike and expected her instructions to be obeyed. When Ena Sharples fainted while waiting to be seen, the sister told off the nurse for letting Ena bully her into letting all her friends be seen before her. She also refused to give Hilda Ogden Stan's whereabouts in the hospital, claiming to be too busy. She showed her softer side occasionally, such as when she gave the nurse two minutes to call her young man but sternly reminded her that it was a hospital.
The sister was the first to notice that Elsie Tanner had disappeared from casualty, having walked out of the hospital and hitched a lift home despite an unexamined wrist injury.
- The sister's name was given in dialogue. She was credited as "Senior Sister" (Casualty).
