Ivan (The Blacklist)

A programmer for the NSA is killed in a supposed car accident, but further inspection reveals that his car was hacked. While investigating the programmer's death, the task force learns that the NSA was working on a prototype device called the "Skeleton Key", capable of hacking into the entire American computer networks infrastructure. Reddington initially believes an elusive Russian hacker named Ivan (Mark Ivanir) is responsible for the theft, but a personal meeting with him reveals that Ivan never had any problems with the United States, and instead is solely focused on the Russian government. Ivan claims that someone else has been masquerading as him. Further investigation into Ivan's claims leads the task force to high school student Harrison Lee, who was responsible for the theft of the Skeleton Key. Lee stole the key and used it for his own ends in order to enter a romantic relationship with the daughter of one of the Skeleton Key scientists. Elizabeth investigates the disappearance of Jolene/Lucy after being approached by Lucy's former parole officer. Elizabeth discovers Tom's makeshift headquarters after Aram is able to trace the origin of Lucy's last voice message, but Tom has just torn down and burned all photos of Red and Elizabeth. He performs a sneak attack on Liz at the hideout, and flees before she can recognize him. During the aftermath of the Skeleton Key crisis, Elizabeth receives an email containing gathered evidence from the parole officer. In a photo of some trash taken in Tom's hideout, she sees an educational toy that she had given Tom the morning of the investigation. Finally understanding Red's repeated warnings about Tom and upset by the recent revelation, Elizabeth turns to Red for emotional support. Red refurbishes an old music box whose song Elizabeth knows from her childhood, and gives it to her as a gift.
