Review Abigail’s stage directions in line 1038 and Mary’s response in the following line. Why does Mary plead with Abigail? What do Mary Ann Proctor have at stake?

I'm not sure about the stage directions. Mary knows Abigail is trying to intimidate her in court and it is working. She wants Abigail to stop her performance pretending that she (Mary) is sending out evil spirits. The lives of all of these girls are on the line.
