Quotes[]

Castle: What is it about full moons that bring out all the crazies?
Beckett: I don't know, you tell me.
Lanie: Looks like a patient lost his patience.
Castle: Also, his command of grammar. "Your" should be you apostrophe r-e as in you are, that's not even a tough one, not like when to use who or whom.
Beckett: Do you really think that's the takeaway here, Castle?
Castle: I'm just saying whoever killed her also murdered the English language.
Ryan: How you doing, Dr. Perlmutter?
Perlmutter: Shh! The body is speaking.
Esposito: What's it saying?
Perlmutter: It's saying, "someone shot me."
Esposito: Loser wears a dress to the precinct for a week.
Ryan: And why stop there? Loser also shaves his head. Or are you chicken?
Castle: You're on, honeymilk.
Esposito: Honeymilk.
Ryan: Damn it.
Castle: It's a common mistake, but it's not ironic that Dr. Cosway's not here for you to lean on; it's just simply tragic. It would be ironic if her death made you feel better.
Beckett: Are we really rooting against solving a murder?
Castle: Well, I don't want to shave my head, do you?
Beckett: Why would I shave my head?
Castle: You're in on the bet, aren't you?
Beckett: Yeah, but I didn't realize...
Castle: makes razor buzzing sound as he moves his hand over his head

Trivia[]

Storyline[]

  • Castle often jokes about bringing popcorn to events that promise to turn wild. On this full moon, he does exactly that.
  • At the crime scene where Castle says "You know, if this was one of those super science-y forensic shows, stick some electrodes in these fishes' brains. Get a fish-eye view of whatever they saw." is a dig at the crime show Bones (2005-2017). TJ Thyne plays Dr. Jack Hodgins, an entomologist, botanist, and mineralogist who is an expert on spores and minerals. He can estimate time of death from insect larvae in human and animal remains and is called "Bug Boy" in the series by Agent Booth. Dr Temperance Brennan was also an award-winning and popular novelist in the show, who wrote bestsellers, just like Castle.
  • This is the first episode to feature Ryan's occasional nickname, "honeymilk". It refers to the warm milk and honey nightcap he shares with Jenny to help her sleep.
  • Castle wonders how a killer who writes a message on the body of the person he just murdered could make such an elementary grammar mistake when the message is important enough to kill to send. While this seemed inappropriate when, it actually illuminates the case. The killer didn't care about the message at all; it was purely a red herring meant to throw off suspicion.
  • Serendipity 3 is a restaurant on the Upper East Side of Manhattan that is famous for its ice cream desserts.
  • Beckett says that this case is proof that any two people can be connected. Ryan draws a parallel to the movie, Crash, which centers on a group of unrelated people who all end up connected to one another. Castle compares it to Six Degrees of Kevin Bacon.
    • This is a game that states any actor can be linked to Kevin Bacon by no more than six acquaintances.
    • Nathan Fillion's "Bacon Number" is one. The two worked together in the 2010 film, Super.
    • The game is based on the concept of six degrees of separation, which states that any person is connected to another through six acquaintances.
  • Castle calls Beckett "Debbie Downer" when she says their suspect in the two cases may be a coincidence. The name refers to a character from Saturday Night Live from 2004, played by Rachel Dratch.
  • The building that Castle and Beckett approach Mr. Cosway at when he is leaving to meet the movers at Ashley's office is actually the "Ninth and Broadway Building" on Broadway St. in Los Angeles, California.
  • When Mr. Cosway says that he bought a slice of pizza at Ray's, Castle asks, "Original Famous or Famous Original?" This is a reference to coming events in "Slice of Death", in where three pizzeria owners named Nick fight over who was the original Nick.
  • The case hinges on the saltwater compound, which was found in trace amounts on both victims. Later, the compound was confirmed not to have come from Ashley Cosway's office. Instead, they found it came from the Hudson River from where the two men took a water taxi every day.
    • The Hudson River is fresh water, not salt water. However, this episode is accurate in that around New York City, the water becomes brackish from emptying into the Atlantic Ocean. And as the tide comes in, the Hudson becomes salty for several miles upstream.
  • Beckett knows about Girl Scout cookie selling in February. It's possible she could have been a Girl Scout.
  • Alexis and her first boyfriend Owen broke up.
  • This is the first time two M.E.s work together in this episode.
