Nikita (Peta Wilson) and Michael (Roy Dupuis) pose as husband-and-wife mercenaries. Their mission is to capture an elusive chemical-weapons terrorist. Will this assignment add an additional strain to Nikita and Michael's relationship? There isn't much time to ponder this possibility during the episode's climax, in which Nikita risks a horrible death while attempting to disarm a canister of deadly gas, wired to detonate in a crowded train station. ~ Hal Erickson, Rovi
