Esposito doesn't appear nearly as excited as Castle but we're really hoping that the boys are all playing nice this week and no longer lying or stealing things from one another.

We don't know what Castle's found in that magazine but he certainly seems excited about it.

Rick is planning a surprise for Beckett on their first wedding anniversary on Castle. "The Last Seduction" is the seventh episode of the show's eighth season.

Besides, everyone knows that Javier Esposito and Kevin Ryan are the real "Cool Boys" in the house. Check out Castle Season 8 Episode 6 on Monday, November 9th on ABC.

We think Ryan and Espo are more than happy to slap the cuffs on Slaughter if there's a reason.

Well, if Ryan and Esposito barreling in with guns drawn is any indication, we'd say things are about to get pretty tense.

So just how tense will things get between the rough, gruff, detective and the husband of the 12th precinct's new Captain?

We know from his last visit that Detective Slaughter likes to play rough but that just isn't Richard Castle's style.

Detective Ethan Slaughter returns. What kinds of trouble will he get Rick Castle into this time?

An investigation into a vampire fetish community eventually wrapped up with Rick Castle throwing an epic Halloween bash for all of his friends. Castle actually wore two costumes in Castle Season 2 Episode 6, “Vampire Weekend” The first was from Nathan Fillion’s cult favorite Firefly character Capt. Mal Reynolds but for the actual party he dressed as one of his favorite authors, Edgar Allen Poe. Our favorites were Lanie as Cat Woman and Martha as Cruella de Vil.

We're hoping everything turns out okay but brown paper bags don't really seem Castle's style. Maybe he'll break out the good stuff when Kate finally comes home.

And why is Martha's friend at the 12th precinct with Rick? How is she wrapped up in the case?
