Well Ben needs her to get out of the house to school and such so I can't imagine him not eventually finding out Violet is dead. Kinda stinks about Larry getting locked away, he was a cool character. So now we only have Ben, Viven, Constance and Luke left that can interact with the world outside of the house. At least on Halloween all the spirits can get out of the house for one day.
Got to say this weird little show has really grown on me.
