An updated title sequence was introduced with the second episode of the fourth season of Person of Interest. Similar to the title sequence of the third season, the updated sequence includes surveillance shots, but the information is overlaid by Samaritan instead of the Machine. It also features a preview of all five main characters. In contrast with previous seasons, Finch's voiceover narration begins with “We are being watched” instead of “You”.
|“||We are being watched. The government has a secret system — a machine — that spies on you every hour of every day. I designed the Machine to detect acts of terror, but it sees everything. Violent crimes involving ordinary people. The government considers these people irrelevant. We don’t. Hunted by the authorities, we work in secret. You'll never find us. But victim or perpetrator, if your number’s up, we’ll find you.||”|
