|“Jack, what's going on? You can tell me. I'm not just your principal, I'm your mother.”|
|— Rose, to Jack|
Rose Davids had a son named Jack Davids and resided in Boston until she got a job as Headmistress at a school located in Newbury, leading to Rose and Jack moving from the city to the small town. Unknowingly to her, the scientist J.B. Watt, who is also a teacher at the same school Rose works in, recruited her son as a Ghost Hunter along with local teenager, Parker L. Jackson and the school's janitor, Douglas Elton. Jack was also reunited with their family's deceased dog Spencer, who returned as a ghost.
Rose was called to the school, along with Bob and Linda Jackson, by Mr. Clarke for a parent-teacher conference so that Jack and Parker can explain why they missed an assignment. Since Rose is the Headmistress and had to wait for them at the school's entrance, Linda and Bob brought both Parker and Jack to school. When everybody arrived, Rose pulled Jack aside to talk to him privately and asked him what was going on, reminding him that she wasn't just his principal, but also his mother but Jack, knowing he can't let her know about him being a Ghost Hunter, reluctantly brushes her off and walks away.
At the science classroom, Rose tried to apologize to Mr. Clarke for their children's behavior while Linda and Bob talked nonstop on the phone with their associates. However, the parents were attacked and gloomed by Mr. Clarke, who was possessed by Mamali. The Boss Ghost told Parker and Jack that she was going to take their parents to the Hidden Side in order to expose their identities and made the gloomed parents chase after their children. Luckily, Parker managed to capture Mamali while Jack freed the adults from their possession.
Rose, Linda and Bob then woke up with no recollection of the events, so Jack and Parker lied that they had fainted upon hearing that the children received many days of detention at night (so they could have more time to hunt ghosts). Linda believed that the punishment was a little harsh while Bob claimed that it would teach their children a lesson, to which Rose agreed before urging everybody to leave and get some dinner.
Rose is briefly seen in a video in Jack's room while Jack was trying to record a video for his suscriptors while she was about to take his trash bin out while he was recording, until he noticed her and reprimanded her for being in his room without his consentment.
Rose is a middle aged woman with short brown hair in a pageboy hairstyle and has a beauty mark on her right cheek. She wears a navy blue pant suit with six white buttons and white trimming in the lapels, a lilac, pinstripe dress shirt with dark violet stripes, black square glasses and a pearl necklace.
Rose is a gentle woman and a caring mother to Jack, as shown when she became worried about her son when he missed an assignment and gently tried to get him to talk to her about that rather than being angry at him. However, she agreed with Jack spending many nights in detention as punishment for missing an assignment, showing that she can be stern when she feels it is necessary.
