Castle 4x13 Moment: Beckett are you wearing perfume? For future reference, I'm partial to Fracas

Castle 4x13 Moment (An Embarrassment of Bitches) Castle and Beckett are in the precinct with Espo and Royal which is a dog trained to sniff/detect presence of heroine. Suddenly Royal starts scratching the floor (his way to indicate presence of heroine). They don't know where that scent is coming from. Rick asks Kate “Are you wearing perfume? And just for future reference, I'm partial to Fracas.” (Fracas – a brand of perfumes) She tells him not to flatter himself.
