Cool Boys, The Last Seduction, And Mr. & Mrs. Castle Scoops

Nov. 9, "Cool Boys": With Beckett away at a work function, Castle is swept up in a caper involving Detective Slaughter (returning guest star Adam Baldwin) – meaning, bro time that affords Rick a chance to vent about his muddled marriage. "What we tried to do was have a bit of the 'guy' conversation about what's happening, but put that perspective on its head," says co-showrunner Alexi Hawley. And in part due to gruff Slaughter's unexpected insights, "It ends up being a positive conversation."

Nov. 16, "The Last Seduction": All My Children alum Lindsay Price and Rescue Me's Andrea Roth are on hand for a "very fun episode" centered on Rick and Kate's first wedding anniversary, says co-showrunner Terence Paul Winter. "But how do you celebrate when you're having this weird 'time out'...? Well, they find a way." Also: Ryan and Espo attend therapy! 

Nov. 23, "Mr. & Mrs. Castle": The fall finale, per its title, is a nod to Brangelina's Mr. & Mrs. Smith -- namely, "the fun of the conflict in that relationship in the movie," says Hawley. On what note will it leave fans heading into a 3 month hiatus? "We're not leaving you with a cliffhanger," says Hawley, "but the promise of what it will be like when we come back."
