Trivia: In this episode, Castle says the words "My partner is crazy and may start firing at any moment" in Chinese. Beckett then asks him "Semester abroad?", to which he replies "Nah, a TV show I used to love". This is a reference to Firefly, a TV show starring Nathan Fillion in which characters occasionally spoke in Chinese.THGhost
Beckett: Murdered Medina just to boost ticket sales? No, that would make this Scooby-Doo... And I'm not Velma.
Castle: Velma, you kidding? You're Daphne... You're hot, smart, not aggressively brainy, but long legs, short skirt...
Castle: Got it.
