Baaya worked as Marnie's governess or nanny at the Marsh House. She supervised Marnie, especially when the child's parents were away. Baaya joined other staff in mistreating the girl. This included verbally threatening to lock Marnie in a decaying silo as punishment, actions which intensified Marnie's fear and emotional suffering. Her conduct contributed to the neglect and abuse Marnie experienced, worsening the child's sense of isolation and vulnerability within the wealthy yet emotionally barren household. Baaya's role signifies a profound failure in caregiving that affected Marnie's formative years.
