Aiden confronts Waltz, who reveals that Aiden's memories were suppressed, and that Mia is actually Waltz's daughter, who he has been trying to cure of an aggressive strain of THV, for the past 15 years since the military incident. Waltz refuses to abort the missile launches, as that would require shutting down X13, whose facilities are necessary to cure Mia, forcing Aiden to battle him. Aiden finally manages to defeat Waltz, who succumbs to his wounds, but the GRE key is destroyed in the fighting. Lawan then tells Aiden she plans to detonate explosives to destroy the missiles before they can launch, which will destroy X13 and possibly herself. Aiden must choose to either try and save Mia, or save Lawan.
