When Captain Cragen returns to the crime scene, while he is facing the camera the blue collar on his bullet proof vest is flipped up, obscuring the collar on his dress shirt.

While discussing the inmates Rebecca had been helping, Kyle tells Benson and Stabler about a specific inmate who relapsed on IV drugs just after getting out of prison. At 7:18, Kyle says that "she even crawled into bed with the guy to help him through the DTs." However, this would not have been possible because IV drug users do not experience the DTs. Also known as "Delirium Tremens," the DTs are only suffered by alcoholics going through alcohol withdrawal.
