Continuity mistake: Early in the episode in the aftermath of the shooting in the pawn shop in which the two glass doors have been shattered and all glass has fallen, there are scenes with large sections of broken glass in the doors.
Plot hole: When Scola and Nina enter the suspect's apartment and begin the search, Nina, before she enters one of the rooms says to Scola " come in here you should see this" indicating that she was aware of something important in a room that she had not yet been in.
