What happens when John Hale Interrogates tituba? How does the scene's atmosphere become hysterical?

Hale confronts Tituba. He says that if she loves these children she must let God's light shine on her. Hale asks if the Devil comes to her with anybody else. Tituba admits that the devil has come to her, and that the devil promises to return her to Barbados.
