"Nukebusters"
The FF realize that they are not in their own universe as the US prepares to launch a preemptive strike from the USSR, who are still being ruled by Joseph Stalin. The FF use E.M.P. tech created to the alternate Reed to render the nukes of both sides inert. The FF slip into Moscow and plan a face-to-face with Stalin.
