Continuity mistake: Frank and Henry are up late, 3am, and, talking about how his late wife Mary never wanted to see her youngest go into the Family Business. Henry says how proud Mary was in the day of Jamie's graduation. But Mary was already dead by the pilot, when Jamie graduated.
Factual error: During the funeral towards the end of the episode, both Jamie and Eddie are wearing white shirts with their dress uniforms. In the NYPD, only Lieutenant and above wear white shirts, like the show has portrayed. The color doesn't change for the dress uniform. (00:38:35 - 00:41:14)
Continuity mistake: Toward the end of the episode when the older mobster is walking from his car down a narrow alleyway toward home, he passes under a low hanging outdoor light fixture. When he is accosted by the other mobster with a gun they are standing with the light fixture between them. There is no movement, but when the police arrive, the light fixture is well behind the guy with the gun.
Continuity mistake: While Danny and Baez are questioning Damian about Mason's whereabouts, Damian's right handcuff switches to the opposite way depending on the angle of the shots. Either the single metal bar faces up or the double bar faces up, which is quite impossible to change when it's locked around his wrist.
Continuity mistake: When Erin is in the ladies' room walking toward the door, she finds Anthony "lurking" in the hall, and Erin's eyeglasses which are hanging from her crew-neck top go from facing her right side, to her left side, then back to her right side, between shots. (00:31:55)
Continuity mistake: As Danny and Jaime are at the range shooting near the middle of the episode, their targets from behind and the grouping of shots they take are really tight together. When they retrieve their targets a minute later, the grouping from the front is completely different and further apart than what was seen from behind the target.
