EW has some spoilery bits to share about next week's Ghostbuster themed Halloween episode, "Demons". Plus, Beckett's PTSD will resurface again in an upcoming episode.
Any minor creepy moments are off-set by loads and loads of humor and some especially great Castle and Beckett banter as the two debate the existence of the paranormal. However, I warn you that not all the couples on this show will end the episode on great terms.
An upcoming sniper case will find Beckett dealing with her PTSD in a big way. “It forces her to deal with her unresolved issues about her mother — and her own emotional choices,” says the source.
