Plot summary
Birkhoff tells Nikita about Heidecker, who helped develop kill chips and other technologies for Division. Recently, Heidecker pays monthly visits to Kosovo to check on Deputy Prime Minister Kosta Beciraj. Beciraj lost a leg following a failed assassination attempt by the CIA, but it had since been "regrown" with real flesh and blood over carbon-fiber bone. Nikita goes on a secret mission to retrieve Heidecker alone so he could bring "back" Michael's hand, until Alex and Michael discover this. After Nikita is captured by Kosovo Security Forces, Alex and Michael go after her.
After they rescue her, Alex assassinates Beciraj and blames it on a bodyguard. They escape with Heidecker, but after the team learns that Heidecker is using children as lab rats for his experiments, Nikita kills him when he turns on them. Spencer's advisor Evan Danforth is apparently impressed with Division's assassination of Beciraj and hands Ryan four files of secret assignments, much to Nikita's chagrin, as she does not want Division to return performing kill missions.
