Mary Warren works in the Proctor household. She is their servant, presumably taking the position that Abigail herself held at one point in time. Mary is easily intimidated, and certainly is intimidated by Proctor, himself. This is seen in Act I, when she scampers off rather quickly when Proctor questions her. In Act II, though, the hysteria of the witch trials have empowered Mary Warren, who serves on the jury of accusations in Salem. This enables her to display some level of power and resistance against Proctor. As Act II concludes with Elizabeth having been arrested, and the relationship between Proctor and Mary developed. Proctor recognizes that Mary understands the nature of Abigail's accusations and demands that she confess Abigail's sins to the court. It is this motivation in that underscores their relationship in Act III. In the trial, Proctor's relationship to Mary is one that seeks to advise. While she is visibly shaken at what she is going to do, Proctor provides a sense of resolve and support to her. Undone by Abigail and the girls' mocking of her, Mary Warren ends up repudiating the relationship between she and Proctor when she accuses him of witchcraft, out of confusion and the desire to be accepted. It is this arc or trajectory of development that shows Proctor's relation to Mary Warren.
