" The removal of Lenin prevents the October Revolution from successfully taking place , causing Hitler to not perceive Russia as a threat . The full weight of the Nazi war machine was therefore directed at Western Europe and the United States . Vosk seeks an alliance with Enterprise , releasing Mayweather and Tucker in hopes of forging a new understanding with Archer . Medical scans soon reveal that Tucker is actually Silik in disguise and he and Archer realize they need each other 's help . They enlist the help of the Resistance to destroy the shields of the Na 'kuhl complex and to help rescue Tucker .
