What two major events occur at the end of act 3

Rev. Paris had seen both Betty and his neice Abigail dancing in the forest with his slave Tituba. Before he came most of the girls ran in fear of being seen. Betty and Abigail were the ones who had got caught. That evening in the forest, he also saw Tituba waving her arms over a fire, a dress on the ground, and someone naked running around their circle. John Proctor said " I'll tell you what's walking Salem-vengeance is walking Salem. Now crazy little childern have the keys of the kingdom".
