Did You Know?


At the beginning of the episode, as Beckett and Castle approach the crime scene, they compare themselves to other crime-solving couples, and Beckett comments that Castle "still reminds" her of Hooch from Turner & Hooch (1989). She first makes a comparison between the two in "Castle: Deep in Death (2009)". See more »


When hostages are taken, HRT (Hostage Rescue Team) is called in, which NYC does not have. In New York City, the NYPD ESU (Emergency Service Unit) would be the division handling the situation. See more »


[first lines]
Richard Castle: So what do you think? This feels different, doesn't it?
Kate Beckett: What does?
Richard Castle: Rolling up to a crime scene as a married couple. We're like Nick and Nora Charles.
Kate Beckett: No, like "McMillan & Wife".
Richard Castle: "Hart to Hart".
Kate Beckett: "Turner & Hooch".
Richard Castle: Turner and Hooch aren't even married.
Kate Beckett: Yeah, but you still remind me a little of Hooch.

Average Castle
25 November 2014 | by slimfanSee all my reviews

I enjoy Castle - big fan of Nathan Fillion - but their Production Designer & Wardrobe person leave something to be desired.

As a New Yorker, I can usually forgive the obvious non-New York locals (like the #7 train going to Brooklyn) but this episode just went too far. Firstly, there has NEVER been a subway car that looks remotely like the car in this episode. Secondly, the turnstiles are all wrong. Thirdly, they can't decide if this is a 7th AVENUE station or a 7th STREET station - the outside sign read "7th Avenue" and the sign inside the station read "7th Street" - they're not the same thing.

Worst of all though is that the wardrobe stylist is completely unaware that the Metropolitan Transportation Authority PD does not patrol or have anything to do with the NYC Subway system; that's the exclusive job of the NYPD. Officer Aragon would never be on duty or even in uniform on the train.

So the plot of this episode was weak but the production design spoiled what would otherwise have been a mediocre episode.
