Complete story — includes the ending

Kelly's men chase; Sydney radios APO. Marshall discovers its deletion. Jack tasks APO, recover the transmission and uncover the Prophet Five mole inside Langley. Security takes Rachel's phone, which scans the code that Grace enters in Payroll to unlock ECHELON Archives ( and WITSEC for the identity of his wife Amanda's murderer). Decoding Enigma, Marshall distracts the tour guide; Dixon triggers Anthrax alarms. Rachel must pull the hard-drive to recover purged data, triggering lockdown. Weiss and Marshall help Rachel escape guards; Dixon extricates Grace. Finding her records and ultrasounds in sickbay, Sydney collapses. Marshall determines the mole has the highest CIA Alpha-Black clearance, narrowing suspects to directors with STU cellphones. Jack meets all seven. Arthur Devlin scoffs, "This meeting is over." Marshall dials; the mole is Jeffrey Davenport. Jack shoots him twice, "Where is she?" breaking his nose. "The Athena...North Atlantic." Security arrests Jack; Dixon mounts a rescue. Sydney undergoes surgery; Dr. Lynn operates! When APO arrives, Sydney is alone. Marshall discovers Grace decrypted WITSEC without permission. Tom finds Karl (alias Allen Korman) speaking German, who apologizes, "Peter...I was under orders." But Peter (aka Thomas Grace ) needs to message "The Cardinal." Jack explains they corrected Sydney's placental abruption, saving her baby.
