Peter appears to be one of her favourite students along with the rest of the Best Boys Club. While she is aware of Henry's horrid behaviour she is one of the only adults to not tell him off for it.
In the Movie her role is slightly expanded, she is shown to overhear the conversation between the school inspectors and the Headmaster of Brickhouse and their plan to close down Ashton Primary but she gets caught. Later when Peter and his friends come to rescue her, they use her phone to reveal his whole plan to Miss Oddbod.
- In the episode Horrid Henry Alone at Home, Peter tells Henry that Miss Lovely said a 20 year old rock at Stone Park is nearly as old as her. This implies that she is at least in her early twenties.
- She is portrayed different in the books, show and movie as in the books, she is rarely temperamental, in the show, she is calm and peaceful and in the movie she is intelligent.
