She thinks nothing of it, but Jed takes it very seriously, and his sister Mary tries to break up the relationship. When Gordon pays a surprise visit to the farm to see Dorothy and she greets him warmly and kisses him, Jed realizes that he's been played, and after Gordon beats him in a fight, Jed kills himself. Mary, outraged, vows vengeance on Dorothy.
