Writer Jonathan Nolan told EW that while he hopes viewers get a small piece of the serialized element in every episode, he’s also peppered a number of important mythology episodes throughout the season. One of those is Episode 9, which is a big episode for Det. Carter, played by Taraji P. Henson.
“One of the fun things to do is to take someone who you’ve developed a rapport with episode after episode, but maybe you haven’t discovered as much about them as you want. Then, you get a chance to put that person in the spotlight for a minute.”
