"Asylum" is the 21st episode of the fourth season of the American television drama series Person of Interest. It is the 89th overall episode of the series and is written by Andy Callahan and co-executive producer Denise Thé and directed by Frederick E. O. Toye. It aired on CBS in the United States and on CTV in Canada on April 28, 2015.
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 receives the numbers of Dominic and Elias and work to solve the conflict once and for all. However, their mission is also connected to Shaw's possible location, which may be located at a psychiatric hospital.
According to Nielsen Media Research, the episode was seen by an estimated 8.45 million household viewers and gained a 1.4/4 ratings share among adults aged 18–49. The episode received critical acclaim, with critics praising the writing, performances and set-up for the finale.
