When a crystal is magically stolen from the abandoned house, the Circle decides it was the traitor witch working with Eben (guest star Sammi Rotibi) so Jake (Chris Zylka) calls for a meeting with Isaac (guest star JR Bourne) to see if they can get him to change sides. Cassie's (Britt Robertson) loose grasp on her dark magic threatens to destroy any possible alliance when their pursuit of the traitor leads them to the "Creepiest Place on Earth." Meanwhile, Faye (Phoebe Tonkin) and Jake (Chris Zylka) work together to steal Dawn's (Natasha Henstridge) crystal, Melissa (Jessica Parker Kennedy) and Adam (Thomas Dekker) pair up and uncover a new magic trick. Meanwhile, a frustrated Diana (Shelley Hennig) reaches out to Charles (Gale Harold) for help.
