When Reid explains the binary code, the alphabet is shown with each corresponding binary code (A = AAAAA). However, C = AAABB was used when it should have been C = AAABA.
Just before the first murder, as the soon-to-be victim goes to bed, there is a glimpse of her alarm clock. The clock reads "11:06" (presumably night-time because it is dark outside), and below the date the clock reads "Tuesday." Time passes and the clock reads "1:13" (presumably early morning because it is still dark), but the clock still reads "Tuesday" below the time.
At the end of the episode, Hotch asks Morgan if he still wants to be stuck with him for three hours, referring to the amount of time they would be in a car together driving back from New York. However, it takes five hours in optimal conditions to drive to Washington, D.C., and Quantico is even further south in Virginia.
In the scene during which the medic applies the clamp to the open wound in Kate's back, there is a close-up of Hotch's arm holding her severed artery. The sleeve of his shirt is almost clean, although before and after it is drenched in blood.
When the unsub is leaning against the fence, there is a delivery truck in the background from "Bernero Hospital Linens" written on the side.

At the beginning of the episode, the fifth person who had been shot was facing the camera with the wall on his right and the subway on his left. The unsub came from behind the victim, shot him, and passed the man on the right side. When Hotch was presenting the case to the team, he showed the video from the security camera. On the tape, the wall was on the left side of the victim and the subway was on his right side. After he shot the man, the unsub passed the victim on his left side, exactly opposite from the original scene.

When he sees Mr. Corbett approaching his daughter's body, Det. Jarvis asks the BAU agents if they want to "Rochambeau" for the privilege of speaking to him. "Rochambeau" is another word for the game rock-paper-scissors.
Garcia was the new girl in 2004 and Reid thought her name was "Gomez." This was the first time Morgan called her "Baby Girl."
In the scene where JJ and Emily are talking about bureaucratic red tape, they are seen entering the Bernero Brothers building.
When Keri and Ryan opted to "pretend" there was no crazy man, they hear their dog barking and found him out the gate, which could only be opened from the inside, was open and the dog was gone. A few scenes later, Ryan sees the man walking his dog, who had just parked his car, and there was no gate or fence. Keri even looked out the window before she was abducted.
JJ refers to a letter that Keri Derzmond wrote to the Silver Spring Police. Silver Spring, Maryland, is an unincorporated part of the county and doesn't have its own police department. There is a Silver Spring office of the Montgomery County Police Department, which is where Keri Derzmond would have contacted.
It is revealed in this episode that Rossi has been married three times.
