RIP, Grandma Jane (Ashley Crow)! Although she spent most of Season 1 in a confused fog, we’ll still miss Cassie’s (Britt Robertson) granny. We’re also worried about what her death is going to do to the dark-magic-wielding witch.

In the producer’s promo video for Secret Circle Season 1, Episode 20, “Traitor,” Cassie says to Diana (Shelley Hennig), “I know that you’re upset, but the witch hunters are closer than ever. They killed my grandmother last night.” Basically, Diana has problems, but Cassie has bigger problems. Yet the little blonde witch isn’t known for her emotional stability, and a conversation with her pops makes us think she’s coming unhinged.

When he tells her the witch hunters are a threat, Cassie tells Blackwell (Joe Lando), “I want to destroy them. Now, more than ever.” Chilling, C! Let’s hope Cassie doesn’t mind choke anyone to death in this episode.

The preview video also highlights the terrifying sights at the carnival the Circle visits to find the last crystal. All we can say is, how’s your coulrophobia, because there are tons of clowns in that place.
