When the Russian mob leader Benny D'Agostino is executed in a convenience store at Brighton Beach, Carter, Fusco and other police officers investigate the crime scene. Detective Bill Szymanski explains the war between the Russian Mobsters and the Italian Mafia led by the mysterious Elias and the hit was a retaliation and shows the surveillance tape to Carter and Fusco. Carter notes that there a witness, an ordinary bald man, who fled after the killing. Meanwhile, Reese is investigating the schoolteacher Charlie Burton, whose number was provided to Finch by the machine. When Det. Fusco calls Reese asking him to find the witness, Reese tells Fusco that he is watching Burton. He sees the Russian mobsters arriving at Burton's building, but Reese protects and flees with him. Burton is wounded and Reese escapes with him to a building controlled by the Bulgarian mob to escape from the Russians. But their leader contacts the Bulgarian leader and make an arrangement to hunt down Reese and Burton. Meanwhile, Reese's cellular breaks and he is not able to contact Finch, who discovers a rogue police officer from the mob.
"Witness" is an excellent episode of "Person of Interest", with a surprising plot point in the end of the show. This twist would be enough to say that this is an excellent episode, but the plot has many betrayals, surprises and wonderful conclusion. This time, Reese and Finch are lured and misinterpret the output from the machine. My vote is nine.
Title (Brazil): "Witness"
