"Nightswimming" is the eighth episode of the American television police procedural fantasy drama Awake, which originally aired on NBC on April 19, 2012. Written by Leonard Chang and co-executive producer Davey Holmes, "Nightswimming" was watched by 2.8 million viewers, including 0.9 percent of those aged between 18 and 49 in Nielsen ratings, upon its initial broadcast in the United States. Directed by executive producer Jeffrey Reiner, this episode received generally mixed reviews. Awake centers on Michael Britten (Jason Isaacs), a detective living in two separate realities after a car crash. In one reality, in which he wears a red wristband, his wife Hannah (Laura Allen) survived the crash, and in another reality, in which he wears a green wristband, his son Rex (Dylan Minnette) survived. In this episode, Michael helps Accountant Marcus Ananyev (Elijah Alexander) and his wife Alina (Ayelet Zurer) start a new life in the Witness Protection Program after a gang member attempts to kill Marcus in the "green reality". In the "red reality", Michael and Hannah prepare for a new life in Oregon after deciding to move there. They go swimming at a college pool to celebrate their love. Many commentators praised the storylines of the "red reality", but criticized the arcs of the "green reality". This episode marked the first absence of Rex, as well as the show's two therapists: Dr. Jonathan Lee (BD Wong) and Dr. Judith Evans (Cherry Jones). Although it was the eighth broadcast episode, it was scheduled to be the fifth episode. The music featured in this installment was by Otis Redding. Michael is seen shirtless in two scenes of this episode, one of which was filmed at an actual campus swimming pool. During filming, a woman who was near the swimming pool confronted Isaacs about his nudity. Several of the episode's themes have been critically examined.
