When John Proctor come with his servant, Mary Warren, to the court, she has guaranteed to come clean. Thus, she admits that the young ladies' showmanship in the court, including her own, were "affectation." as such, they were lies. Reverend Parris says that when he touched her at that point, her skin was icy, and Proctor guarantees the court that she'd just been "put on a show to black out."
