Although the killer had an interesting pathology, this episode was marred for me by the writer, and JJ as the writer's mouthpiece, bending over backwards to give credence to psychic woo-woo.
JJ's desire to believe, and eventual consultation of, a psychic known to be a fraudster rather diminished my respect for her character. However, I didn't think enough of Garcia and Kevin's intelligence to be put off by their eager consumption of newspaper horoscopes. "You might be surprised", says Kevin, but he's such a poorly-written character that nothing he does surprises me.
Rossi is chosen for the voice of reason, disdaining psychic from experience with grief vultures in his previous cases. The psychic clues are misleading at first, but the writer's heavy hand makes sure that Rossi gets his comeuppance in the end.
