The "Person of Interest" episode, "Critical," brought Leon (Ken Leung) on board as a temporary member of the team. He was the person of interest (POI) who annoyed Reese (Jim Caviezel) in the Season 2 premiere. This time, he provides additional annoyances for Finch (Michael Emerson) and Reese -- and humor for the viewers -- by becoming a repeat POI. He just can't seem to stop stealing money from people who want to kill him! Reese and Finch stick Leon with their dog, Bear, while they deal with another POI. Bear is commanded to kill Leon if he even looks at Bear sideways. At least Leon will be safe from the Russians.
The episode has almost too much going on. If you blink, you'll likely miss something important, but it was fast-paced, intriguing, and a nice change of pace for the show -- introducing yet another interesting villain. That makes four criminals who can make trouble for the team at any time (Elias, Root, Kara/Snow, and this new adversary).
Forced to be a perpetrator
Both Finch and Reese have to work in the field when their next POI is a doctor. Madeleine (Sharon Leal), the doctor, must perform surgery on a very important person, Oliver Veldt. Finch donated a wing to the hospital where she works in order to get close to her. The whole situation, including Leon's presence, and the ease with which Finch plants a bug in the POI's glasses is all contrived but highly entertaining, nonetheless. There were just too many coincidences, but it's easy to look past them with so many "moving parts."
Madeleine is confronted by a man named Alistair Wesley (Julian Sands), who threatens to kill her wife, Amy (Erica Leerhsen), if she does not murder Veldt by botching his heart surgery. Madeleine is being forced to be the perpetrator. Finch calls on Leon to use the computers in the library to find out more about Veldt (after giving Bear the command allowing Leon to do so) and sends Reese out to watch over Amy.
Reese protects Amy
Reese easily sniffs out a sniper and takes him out with his own rifle. Wesley calls Reese on the sniper's phone and sets up a meeting with him. The job of protecting Amy is going to be much more difficult than he had anticipated, as Wesley is former MI-6. He also has his own cameras and a whole team of snipers ready to act if Madeleine does not go through with the murder.
Fusco lends two helping hands
Fusco (Kevin Chapman) first works on a completely separate case, involving a dead man who had Carter's (Taraji P. Henson) card with a number written on the back. Once Carter takes over the case, Reese calls Fusco for help protecting Amy. Fusco's job is to create a distraction so Reese can help free Amy from snipers.
Fusco creates the distraction by arguing with a nearby cop. Meanwhile, Reese calls Amy and instructs her how to get to safety. Reese is waiting at the end of the line, ready to beat up the bad guys who are converging on her. Fusco realizes the cop he argued with earlier is one of the bad guys and provides the final distraction Reese needs to disable the cop when he surprises them with a gun.
Finch protects Madeleine
As Reese protects Amy, Finch protects Madeleine from the "inside nurse" who attempts to kill Veldt when Madeleine refuses to do so. Finch knocks her out with one of the overhead movable lights, then assists in fixing the damage done by the nurse. All hands were on deck for this one, protecting the couple from every angle. The only bad part for the team is that Wesley escaped. He has proven to be a formidable opponent, and it will be exciting to see him again in a future episode.
Carter must tread lightly
The number written on the back of the card in the dead man's pocket leads Carter to an address for a business, where she spots Snow. She follows him to a dark hallway, where he gives her a message for Reese: "She is planning something big." Then "she" arrives with guns blazing. Carter escapes, then meets with Reese and gives him the message. Reese warns Carter that she may not want to know anymore secrets, since she still has a life and son to protect. She has something to lose, unlike Reese and Finch.
