Was Mrs Erylnne's decisions right? in act 2

Act II shows just how quickly social relationships can change. Because the guests at Lady Windermere's party believe she invited Mrs. Erlynne, they start to give Mrs. Erlynne a chance. Mrs. Erlynne uses her own devices as well to quickly work her way through the party, charming men and women alike, though some are still confused about how to feel about the relationships of their significant others with her. In other vignettes from the party, Lady Windermere and Lord Darlington's relationship is shown to shift suddenly, going from friendship to potential lovers.
