Levin, while speaking with EJ at the opening crime scene, refers to the "Virginia PD"; however, the law-enforcement agency in question is not the Virginia "Police Department" but rather the Virginia "State Police". There is a huge difference between the two terms.
When EJ is at the office and tells her team to gear up, her hair is down and completely straight. When they are at the crime scene, it is in a perfect French braid. Later, back at the office, it is once again down and completely straight, no waves or any indication that it was ever in a braid.
