Carrie (2013)/A Series of Unfortunate Events (2017) Crossover Prompt 1

Due to the actions of a certain inept banker, the Baudelaire children are sent to live with a mentally unstable, religious fanatic named Margaret White. Completely oblivious to the children's uneasyness at Margaret's appearance, Mr. Poe cheerfully bids them farewell before heading back to the bank. The woman then coldly ushers them inside her house and lays out her strict rules before sending them to the spare bedroom upstairs. The dismayed orphans make their way towards the bedroom door before spotting a blonde teenage girl looking at them through her slightly opened bedroom door. She had a shy look on her face and she quickly closed her door upon being spotted. The three children wondered who she was before entering their room.
