In "The Crucible", what is Elizabeth's response when she is asked whether her husband was unfaithful?

This is an important question in understanding the evolution of the relationship between John and Elizabeth. The three key players all know what's at stake (Danforth, John and Abigail), however, Elizabeth only knows that her moral ethic is torn. On the one hand, if she lies to save her husband's reputation, she may go to Hell, on the other, if she tells the truth, her family and her husband's good name is destroyed. It is not simply that she says, "(faintly) No, sir." to save John's reputation, but that she is willing to condemn herself with the lie. This moment is not only the pivotal point in the play that determines Abigail's innocence in Danforth's eyes, it is also the resurrection of the intimacy between John and Elizabeth. Both now know each other's love and willingness to sacrifice for their love.
