10. The Index

Complete story — includes the ending

Sydney uses Nadia's birthday dinner as a pretext for stealing the key to Sloane's secure phone. Sydney and Dixon learn that Sloane has contacted old Alliance associates. The two conspire to give the CIA a corrupted key to an encrypted database—a master blackmail list. When Sloane arranges a meeting with his old associates, Jack presents them with the key to The Index. Jack is pistol-whipped when the key does not work. Nadia rescues him. Jack and Sloane finally gain access to the list. Vaughn receives a mysterious package from a mysterious 'fake nurse' while visiting his comatose uncle in the hospital. It contains a key that leads him to a journal written by his "late" father, which contains entries after the date of Vaughn's father's alleged death.
