New this week Plot hole: During Castle's time with the hot girl from the interview, just before Beckett arrives, he makes a comment saying that he found out who the killer is by something the girl said. Only problem is that he really didn't. When she said, after he asked how one guy got away, she responded with the line "I can assure you, it had nothing to do with me", before opening her dress and straddling Castle. By this time Beckett overhears them and breaks in, meaning that there wasn't enough time for the girl to actually tell him who the guy was. This also wasn't brought up or mentioned earlier, so Castle did not find out who the killer was; there's no way.
Plot hole: Beckett and Castle lose their cell phones and wallets and are being chased by the mob. Beckett steals a cell phone from a car but can't use it, since it is locked and then shut off remotely. Any cell phone can always dial 911, whether locked or blocked from service.
Continuity mistake: When Beckett and Castle kiss at his party at the end of the episode, the camera is behind Castle, and Beckett's head is leaning toward her left shoulder. When the shot switches to behind Beckett, her head is leaning to the right. Then it switches back to left.
Revealing mistake: After Castle and Beckett are arrested for interfering in Chief Brady's investigation, a deputy tells them that Brady wants to speak to them; Beckett stands up to leave the holding cell, but is held back by the pair of handcuffs chaining her to the bench. The cuff is not actually on Stana Katic's wrist; she's just holding it in her hand.
Continuity mistake: Castle and Beckett are talking about the case in the precinct and his coffee runs out. Beckett offers to go refill the mug. She grabs his white mug in her right hand. In the next shot, it is now in her left hand. A blue mug is in her right hand instead.
Continuity mistake: When Beckett, Esposito and Ryan interview the fruit stand vendor, he states that he saw a bronze Mercedes drive by, to which Esposito replies, "That's Castle's car." In the previous scene at the car crash site, Ryan asks Esposito to check the back corner of the car for damage, which is silver or gray, not bronze, in color.
