Alden and Cotton find themselves face-to-face with a real witch, and an unlikely ally keeps the coven from tracking down their missing sister. Tituba feels left out when Mary decides to initiate a new member into the coven. As Mary takes her new acolyte under her wing, she recalls her own path after the fateful events surrounding Alden’s departure from town seven years ago. Meanwhile, Alden and Cotton learn to their horror that the trials have actually been helping the witches – and soon find themselves under attack after they lose control of their captive.
