SPOILERS - question about after caretaker Edward assaults Florence
When Florence comes out the woods, she mentions Tom, the boy, to Robert, and Robert says (the twist), “There are no boys left, it’s just the 3 of us!” I assumed this meant that Tom was a ghost (of course) and that Maud was too; i.e the “3 of them” are Robert, Florence, and Edward. Then in to the final murder/suicide scene, I kept thinking that Maud was a ghost, while trying to kill Florence. But she’s not a ghost. She dies from the poison, as evidenced and referenced in the following scene.
Am I missing something? If not, what a blunder in the script!
