Jake meets with Isaac again. He says that Cassie is being followed by the Nidaros coven and wonders if they are the witches that Isaac killed haunting Cassie. He says that John Blackwell killed the witches in order to steal their power. When Cassie "activated" the medallion, she alerted every dead witch whose power the medallion has taken. Isaac says that the medallion holds the power of many crystals and she'll die if he doesn't take it with him.
Cassie tells the girls about the ghost she saw in the basement, though Faye is wary that she's going to make the night all about her. They try to talk to the ghosts with a Ouija board, which doesn't work, so Cassie puts the medallion in the center of the board instead. They don't even need to touch it -- it spells "sacred" all by its lonesome. They try to decide what that means, but Diana and Melissa are too fucked up and stupid to be serious. Cassie decides to go see Adam and Jake arrives to talk to her just after she leaves.
Cassie is driving when she passes one of the shrouded witches on the side of the road (she doesn't see it). The medallion's chain tightens around her neck and causes her to have a gnarly car accident! Meanwhile, Adam has his boat all set up to impress Cassie for V-Day. Jake shows up and tells him that less is more. They leave to look for her together and he doesn't blow out all the candles on the freaking boat. Lame.
Cassie seems fine after the accident, except for a cough. Weird. She sees one of the shrouded witches and follows it. Faye and Diana have an argument where Diana accuses Faye of being jealous of her friendship with Melissa. Then they find Melissa convulsing on the floor with an empty bag of Satan Sauce beside her.
