It is the 99th overall episode of the series and is written by Sabir Pirzada and directed by producer Margot Lulick. It aired on CBS in the United States and on CTV in Canada on May 30, 2016.

The series revolves around a computer program for the federal government known as "The Machine" that is capable of collating all sources of information to predict terrorist acts and to identify people planning them. A team follows "irrelevant" crimes: lesser level of priority for the government. However, their security and safety is put in danger following the activation of a new program named Samaritan. In the episode, the team must protect a locksmith who is extorted by a person to commit crimes. However, the team realizes that the person is none other than "The Voice" himself. The title refers to "Sotto voce", which is used to denote emphasis attained by lowering one's voice rather than raising it, similar to the effect provided by an aside.

According to Nielsen Media Research, the episode was seen by an estimated 5.49 million household viewers and gained a 0.8/3 ratings share among adults aged 18–49. The episode received very positive reviews from critics, who praised the writing, action scenes, character development and final scene.
