Plot summary
Hunter and Morse follow Malick to a decommissioned facility in Siberia, where Russian delegate Anton Petrov wishes to build a sanctuary against the wishes of Russian Prime Minister Dimitri Olshenko. Olshenko sends his attaché to shut down the operation, but he is murdered by General Androvich, an opposition minister and Inhuman whose shadow is made of sentient darkforce. Malick suggests that the Prime Minister be invited to the facility himself and that Androvich be unleashed upon him. Hunter kills Petrov to protect Olshenko, while Morse kills Androvich to destroy his shadow.
Olshenko, unaware of the attempt on his life, has the two arrested. Their Interpol interrogator threatens to turn them over to the Russians for execution unless they confirm that S.H.I.E.L.D. still exists, but Morse and Hunter refuse. Ellis intervenes with Coulson; they save the pair's lives on the condition that they never work for the U.S. government again. With the option of working in secret out of the field, Morse and Hunter instead choose to leave S.H.I.E.L.D.
