I have a little spoiler scoop to share with my Castle fans itching for tonight's Halloween themed episode, "Demons". We find our team investigating a murder inside a 'haunted' house, but on the side lines Lanie and Esposito are getting a dose of reality that's not so welcomed.
Jenny~Juliana "mentions marriage in front of Esposito and Lanie~Tamala Jones - ‘So when are you guys getting married?’” Seamus Dever previews. “And that becomes like a time bomb.” Jon Huertas~Esposito goes on to add, “Some things are said that probably shouldn’t have been said in that moment, and it sparks a conversation between Esposito and Lanie that neither one of them were ready to have.”
