in her father's footsteps and effectively becoming Chuck's nemesis. The CIA orders Vivian assassinated, but Chuck refuses to believe that Vivian would hire Damien. In a meet, Vivian gives Chuck a component of a Volkoff weapon known as the "Norseman". Chuck and Sarah visit Volkoff at River Hill Penitentiary, only to learn that he has begun a path to redemption. In exchange for a meeting with Vivian, Volkoff helps Team Bartowski find the weapon's tracking device and killing agent, along the way apologizing to those he had wronged in the past. When Volkoff panics and nearly gets Chuck and himself killed, Chuck encourages him to return to his old ways.
