The only one who might be able to help is virologist Griffin Rhodes, currently in solitary confinement in a maximum security federal prison for alleged terrorist acts, including the attempted theft of WRX3883 from the lab where he worked. Rhodes has no idea why he has been arrested, but when Hilliard offers to free him in exchange for his help combating the virus, he reluctantly agrees to do what he can to support the government that has imprisoned him without apparent cause.
