Complete story — includes the ending
Lauren traces Lazarey's phone calls to a London address and finds that the tenant is Julia Thorne (Sydney's alias for the past two years). Robert Lang designs a device which can interface with all control consoles and bypass all security protocols to any missile silo in Russia. He undergoes plastic surgery to hide from the Covenant. In Milan, Allison, saved by the Covenant, kills Lang, takes his RFID chip, and knocks Sydney unconscious, so the Covenant can recover something hidden in Sydney's memory. Sydney tracks Allison to Sofia, shoots her, and retrieves the device. Allison escapes during transfer to a hospital.
