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.

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.

Always check who's on the other side of that door before opening it. Didn't Castle always tout how he lived in a secure building? Security seems to be lacking.

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

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.

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