When did Gregers begin to put dark ideas into Hedvig's head?
In Henrick Ibsen's play, The Wild Duck, the idea of shooting the duck occurs in three stages. First, in Act III, Gregers has a discussion with Hjalmar in which the metaphor of the wild duck is applied, and Hjalmar criticises Gregers for having dark ideas. Gregers resolves to tell the truth to the Ekdal family and goes for a walk, during which, as we find out later, he reveals Gina's affair.
Ar the end of Act IV, after Hjalmar has shown anger against Hedvig, Gregers suuggests that Hedvig can regain the love of her father by a sacrifice of the thing she treasures most, the wild duck. Although Gregerse suggests that her grandfather kill the duck. he doesn`t understand that Hedvig herself is the wild duck who with be sacrificed in Act V.
