husband for Volkoff. In "Chuck Versus the Cubic Z", Volkoff arranges for her to be on the same prison transfer as Hugo Panzer and hires Panzer to kill her for the failure. For the first six episodes of the fourth season, Volkoff directed his operatives from behind the scenes. In "Chuck Versus the Anniversary," General Beckman assigned Chuck, Sarah Walker, and John Casey to the same task as Mary. Volkoff first appears in person in "Chuck Versus the First Fight."
