When Reverend Hale visits what things seem to go against John and Elizabeth?

1. Abigail’s story. Abigail tells Reverend Hale that she witnessed John and Elizabeth engaged in a sexual encounter with the Devil in the woods and that John signed the Devil's book. The fact that Abigail is the only one who claims to have seen this, besides Mary Warren whose testimony cannot be trusted, casts doubt on the truthfulness of her story and makes it look as if she is accusing the Proctors to protect herself and her friends.

2. Mary’s guilt. Mary Warren confesses to Reverend Hale that she and Abigail lied when they accused other people of witchcraft. This adds doubt to Abigail's credibility, but also to the court’s ability to accurately identify true witchcraft.

3. Hale’s discovery. While looking for evidence of witchcraft in the Proctors' home, Reverend Hale finds a poppet made of cloth. This poppet is considered a strong piece of evidence of witchcraft because it is believed that witches create poppets to bewitch people. However, the poppet was planted in the Proctor's home by Abigail in order to frame them for witchcraft, revealing the court’s unreliable methods of evidence collection.

These factors combined provide strong challenges to the claims against John and Elizabeth, suggesting their innocence and casting doubt on the validity of the witchcraft accusations.
