Once this ceremony is over, Mrs. Alving believes that her late husband will be finally, truly dead. She'll banish her ghosts and moves into the future with only her son as partner.
Mrs. Alving enjoys the satisfaction of letting Pastor Manders know he's full of it. She has suffered and this memorial is going to put the ghost of her dead husband to bed for good.
Suddenly Mrs. Alving's desired path takes a number of left turns. She must dispel the attraction between Oswald and Regina by telling the truth about her husband.
With Regina gone, Oswald requests that his mother be ready to kill him if he has an attack and is left in a vegetative state. Mrs. Alving sees this as an unimaginable act, and yet she agrees to it, believing that it won't happen.
Mrs. Alving faces an impossible decision: kill her son, or keep him as a living ghost.
