Nesterov (Russian: Нестеров) was a Bratok of the Russian Mafia, hired by Junior Soprano, along with Sasha, to perform a mock execution on Christopher Moltisanti for robbing trucks under Junior's protection.
They abducted Christopher after after buying from an ice cream truck, several times punching Christopher in the stomach, Dragging him by the neck to the pier, Nesterov held Christopher down as Sasha cocked his gun and aimed it. Christopher, believing Tony Soprano had put a hit on him for selling crystal meth to his daugther Meadow, pled for his life and how he only did it so Meadow wouldn't be hurt buying meth in a dodgy neighborhood. Sasha still pulled the trigger, but it didnt go off, revealing the gun was unloaded. Nesterov swears disapprovingly after realizing Christopher went number two in his pants and released his grip to cover his nose. The thugs then left, leaving Chrisopher there in pain.
