The girls got caught "dancing" in the woods by Parris
Abigail and Betty accuse many women of the town of witchcraft
Mary Waren gives Elizabeth a rag doll she made
This event is important because it is what leads to the suspicion of witch craft in the town. "Uncle, we did dance; let you tell them I confessed it. But they‘re speakin‘ of witchcraft; Betty‘s not witched."
This scene is important because it puts the witch hunt into action by Abigail and Betty falsely accusing the women. "The marshal, I‘ll call the marshal!" "Let the marshal bring irons" The quotes are indicating that they believe what Abigail and Betty are telling them.
This scene is important because after Elizabeth receives the doll, she is caught with it and is suspected of being a witch. The reader can now suspect that Mary might've set the Proctors up. "I made a gift for you today, Goody Proctor. I had to sit long hours in a chair, and passed the time with sewing."
