Character mistake: Frank implies that Joe is the oldest child, but he was born in 1977 (1x22), Erin in 1975 (6x07), and Danny 1973 (2x17). Erin also claims she wasn't born yet when the murder of Henry's friend took place in 1977 but she would have been about two years old.
Visible crew/equipment: While Jaime talks to Malcolm on the street and takes his picture it's being filmed from two camera angles. When Malcolm shoves Jaime and he falls to the ground we can see the second camera's tripod leg at the right side of the screen, and as Jaime gets up we can see the second camera as well.Super Grover
Audio problem: While at the range, Jamie takes Frank's revolver to the line and fires it. The last 2 shots you can hear the casings hitting the ground, but not on the first 3 shots. The last 2 shots are from another camera angle. Revolvers don't eject the casings, so we shouldn't hear them landing.
Continuity mistake: Henry sets down the pencil he was using on the crossword. In the next shot, as he is picking up his glass, it is in between his fingers. It shows him taking it from his hand with the other, but again in the next shot, is back on the crossword. (00:40:30)Destiny Smith
Visible crew/equipment: After Jaime goes after Malcolm, who was released again from the hospital, it cuts to Danny and Kate parked in the car across the street from the church, and when Kate opens her door the reflections of the camera and crew members are visible on the window.Super Grover
Continuity mistake: Near the end of the episode Frank Reagan pulls up to the house of the woman who has been scamming New Yorkers with the fake 911 charity. Immediately before he arrives she is putting suitcases in the trunk of her car. As he pulls up the suitcases in the trunk are different.bnemirow
