In this scene, the full extent of Mrs. Lyons’ insanity finally emerges. She is so haunted by her past deception that she now puts all the blame on Mrs. Johnstone, believing that the other woman has “ruined” and “cursed” her. Although Mrs. Lyons believes that her son Edward does not really belong to her, this is a delusion that springs from her deep guilt, rather than an actual fact. Even in the midst of her emotional breakdown, Mrs. Lyons still believes that money can fix everything—Mrs. Johnstone, however, has very different ideas. Although she is terrified of the other woman, Mrs. Johnstone shows both courage and compassion here, hearing out Mrs. Lyons’ ranting for as long as she can, and defending herself when Mrs. Lyons becomes violent. This scene completes Mrs. Lyons’ transformation from a snobbish but sympathetic character into an outright villain.
