Here’s the description:
THE OTHER BLACKWELL CHILD IS REVEALED — To protect themselves from the witch hunters, Jake (Chris Zylka), Cassie (Britt Robertson) and Faye (Phoebe Tonkin) seek out Jake’s grandfather Royce, (guest star John de Lancie) to find his family’s crystal and are confronted with disturbing theories about the events of sixteen years ago. Meanwhile, Diana (Shelley Hennig) tries to balance her pursuit of the Glaser crystal with Melissa (Jessica Parker Kennedy) and Adam (Thomas Dekker) with her romantic life with Grant (guest star Tim Phillipps), who demands to know what she’s hiding. At the same time, Callum (guest star Michael Graziadei) attempts to re-insert himself into Melissa’s life. Charles (Gale Harold) and Jane (guest star Ashley Crow) plot their move against Blackwell (guest star Joe Lando). Omar Madha directed the episode written by Micah Schraft (#119).
