Reverend Samuel Parris discovers the girls with the act of witchcraft.
After the situation in the woods Betty (Reverend Samuel Parris' daughter) has been found motionless in bed. Reverend Parris believes this as the cause of being involved with the evil that witchcraft possesses.
A doll has been found in the house of the Proctor's, and it has a marking on the area where Abigail Williams (Reverend Samuel Parris' niece) had supposedly been stabbed.
John Proctor (a farmer), and his wife Elizabeth Proctor have been accused of witchcraft by Abigail Williams. Abigail once had an affair with John, and she is acting out of envy. Furthermore, John is a very religiously devoted man, and his greatest regret is the affair he feels misled his faith and brought him problems with his wife. Even though he isn't guilty, he feels he is due to his sin.
For the purpose of protecting his wife, John confessed, and even though he isn't guilty, he feels he is because of the affair he had with Abigail. He chose to do this because he believes that his relationship with God has been ruined ever since he began the affair.
John Proctor is sentenced to hanging, and nothing stops his death from happening, and that's why Abigail Williams is with an evil smirk at the far right.
