While on the fake date, Det. Lizzie Needham pretends to be Serbian. The actress who plays her, Bojana Novakovic, was actually born in Serbia.
Many elements of this episode point to it being initially penned as the second of the series. For example, Andy and Dylan's conversation about Dylan's decision to return to police work and Lizzy's hostility towards him (as well as the hostility of the precinct at large) would make more sense immediately after the first episode. Most damning, the first episode ends with a hint towards the case of a dead woman who is missing her heart.
