Critics were largely positive in their reviews of the installment. Awake centers on Michael Britten (Jason Isaacs), a detective living in two separate realities after a car accident. In one reality, in which he wears a red wristband, his wife Hannah (Laura Allen) survived the accident, and in another reality, in which he wears a green wristband, his son Rex (Dylan Minnette) survived. In this episode, Michael and Isaiah "Bird" Freeman (Steve Harris) are investigating what seems to be a case of gang violence. However, the clues shown to Michael in another reality suggests something deeper. Meanwhile, Hannah is trying to talk through a tough situation with Rex's girlfriend Emma (Daniela Bobadilla).

This episode marked the second absence of Rex, as well as the show's two therapists: Dr. Jonathan Lee (BD Wong) and Dr. Judith Evans (Cherry Jones). It was filmed in Los Angeles, California, while sixteen guest actors starred in this episode. Plot Background The Brittens are involved in a fatal car accident.
