Castle's line "Remember my safe word is apples" is a throwback to Castle: Flowers for Your Grave (2009) in which Castle stated the same word after Beckett had him cuffed. See more »


When Beckett requested an APB in the previous episodes she said her badge number was 41319. However, when she introduces herself to the mistress, it's clear that the actual number on her badge is 0334. See more »


Richard Castle: [seeing Alexis dancing in the living room] Why are you so Beyonce this morning? You got a school dance coming up?
Alexis Castle: No. Ashley gave me some of her cheer routine. She's been on the JV for two years and she wants me to try out for the squad.
Richard Castle: Cheerleading?
Alexis Castle: Yeah. Why?
Richard Castle: Who are you and what have you done with my daughter?

Try as she might Kate Beckett, the infallible super detective, is no match for a real dominatrix
24 October 2013 | by See all my reviews

The Mistress Always Spanks Twice (2010) is yet another attempt to establish Kate Beckett as not only an infallible super detective, but also a sexual goddess, superior to all those around her. The attempt fails as Lady Irena (Dina Meyer) shows Kate Beckett how to evoke sexuality and capture the attention of a man.

Javier Esposito gives Kevin Ryan a hard time (again) about his girlfriend, Jenny, but is put in his place by Mistress Sapphire (Azita Ghanizada playing a very different role to the one she plays in Alphas). He was all thumbs when undoing her boots. Kevin Irish Ryan subsequently performed the task without incident. At the end of the episode Kevin Ryan introduces Jenny to the team.

It is also interesting to contrast the forced nature of the Kate Beckett character with Megan Hunt (Dana Delany) in Body of Proof: Doubting Tommy (2013). Co-worker and former flame Detective Tommy Sullivan (Mark Valley) acknowledges Megan Hunt to be a very sexually attractive woman. Megan Hunt agrees to engage with him and treats him with some dignity.

Alexis toys with the idea of being a cheerleader, which meant Richard Castle got some parenting advice from Martha Rodgers and Kate Beckett, the infallible super detective (there is nothing she cannot do).

Kate Becket goes through her usual routine of ridiculing and insulting Richard Castle, but ultimately has to concede "In the end Castle was right". Of course that fact will be forgotten very quickly by everyone and Castle will be ridiculed again. Kate Beckett also got her theory of the crime wrong a couple of times, but that will be ignored, because Kate Beckett the super detective is infallible.

As usual the rights of suspects are not a priority for the writers, nor is the concept of admissible evidence.
