Plot hole: If the Lady of the Lake walks every night to her room and kills those in her path, why didn't Flora and Miles' parents die in their room by the hands of the Lady in the Lake when they first moved in?
The Haunting of Bly Manor (2020)
1 plot hole in show generally - chronological order
Starring: Andrew Neil McKenzie, Victoria Pedretti
Factual error: The British schoolroom has a UK flag at the front. American schools might do that; UK schools don't. There's even a little one on the teacher's desk.
Trivia: The character of Dani Clayton is named after Jack Clayton, who directed "The Innocents." "The Innocents" is the film adaptation of the stage version of Henry James' "The Turn of the Screw." (Source: ScreenRant).
