We don't see Beckett back at the loft yet, but it appears that Rick has brought the wine on Castle. "The Nose" is the fifth episode of the show's eighth season.

Is Castle now bringing cases home with him? Maybe he should consider giving up the P.I. business.

Martha looks as though she's happy to see an old friend. She's also wearing gorgeous blue earrings that are so very Martha.

Stephanie Weir guest stars as someone who appears to be an old friend on Castle Season 8 Episode 4, "The Nose"

What kind of stories is Martha sharing about Rick and her family? We'll have to watch Castle Season 8 Episode 4 to find out.

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

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.

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.

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

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

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

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