Reese, using the alias John Wiley, will fly to Istanbul, Turkey, but his flight is overbooked, and the company attendant changes his flight to Rome in the First Class. Then the flight attendant Holly asks him whether he may switch the seat to let a couple in honeymoon together. Reese has no objection and soon he finds a Federal Marshal unconscious in the toilet. Reese calls Finch and asks he is manipulating his flight to send him to another assignment, but he says that he is not. Reese tells the other Marshal where his partner is, and he is rude with Reese and faints immediately after. Out of the blue, a man comes from the rear of the airplane and injects a needle in the tight of the man in custody. Reese knock the man out and sees his tattoo in the arm with the word Lanceros. Reese sits where the Marshal was and asks Finch who Owen Matthews is since the cartel is trying to kill him. Then Reese protects him from two Mossad agents. Finch tells Reese that several countries are looking for a man named The Sphinx, who created a software in the darknet to sell drugs for a lower price. Soon Reese learns that Owen has developed the software and many agencies are trying to kill him, since they use drug money for supporting their secret activities. Meanwhile, Finch asks Shaw to visit her former colleagues from ISA to know why Owen is relevant for the national security.
"4C" is an entertaining episode of "Person of Interest", with Reese working with Finch again. The plot is funny, with the flight assistant Holly helping Reese to control the situation. Finch is the great hero of the show, landing the huge airplane in the airport using video-game accessories. My vote is nine.
