Abigail Williams and John Proctor most likely never had an affair in the play 'The Crucible' as suggested by their own denials and confessions.
Step-by-step explanation:
In the play The Crucible, there is evidence to suggest that Abigail Williams and John Proctor never had an affair.
First, in Act I, Abigail claims that she and Proctor had no romantic relationship. When questioned by Reverend Hale, she says, "I have no knowledge in that line." This indicates that she is denying any involvement with Proctor.
