A Broken Heart
In the final moments of a cooperative mission, Sydney and her Russian nemesis Anna memorize a 500-year-old binary code written by Milo Rambaldi before it is destroyed. Sydney isn't sure if she should give the correct sequence to SD-6 but Vaughn makes it clear that her role as a double-agent is in constant jeopardy.
The completed code represents a geographical location for a church in Malaga, Spain, where Sydney and Anna meet as enemies. Sydney bests Anna in a brutal fight, and recovers a gold circular crystal from the church's stain glass window.
She returns to SD-6, where Marshall's analysis discloses a pre-synthetic polymer, also invented by Rambaldi. The 15th century seer's progressive inventions now appear to be at the root of a much deeper mystery.
Sydney and Dixon are sent on a mission to investigate a plot to eliminate the United Commerce Organization. In Casablanca, Morocco, Sydney adopts the guise of a French-Canadian tourist.
In a crowded marketplace, she attempts to get near Luc Jacqnoud, whose bodyguard recognizes her from a previous encounter in Corsica. After a battle, Sydney arrives to Dixon's aide, and is crushed to find that their contact -- and friend -- Bak Ibrahim, has been slain.
At SD-6, Jack is interrogated by McCullough but we learn, in a dreamlike sequence, that an unspoken truth about Sydney's mother continues to haunt him. Meanwhile, Vaughn's feelings for Sydney, in a moment of briefing, show through even further, finally, when she breaks down to him about the heartbreaking conflicts in the career of a dual agent, Vaughn offers her his support as a friend
Meanwhile, Francie's suspicions grow of Charlie's infidelity, so she and Sydney stake him out until they spy him kissing another girl. Will unravels further clues about Danny's death and struggles with his own feelings for Sydney.
SD-6's latest clues lead Sydney and Dixon to São Paolo, the location of the next United Commerce Organization conference, where Sydney witnesses the method to Jacqnoud's scheme. Dhiren Patel, the Peace Prize winner, is scheduled to speak at the UCO conference, but collapses at an evening social where men impersonating paramedics take him away. Sydney watches from the rooftop as a tiny bomb with a charge equivalent to 300 pounds of TNT is surgically implanted into Patel's pacemaker.
Francie: He has a law review in an hour.
Sydney: You want to follow him.
Francie: So much, I cannot even tell you.
Will: (on the phone) H-E-C-H-T. You're certain? Okay. Thank you. I promise, I won't call again. (hangs up) Danny was supposed to be registered at a medical conference in Singapore. . . . But I checked all the conferences twice. He's not registered at any of them.
Sydney: And the bank called. Uh, I might have another trip.
Will: You take an insane amount of trips.
Vaughn: What wife? I have no wife.
Sydney: No, there was a picture in your office. You and that woman. I thought you were married.
Vaughn: No. She and I are not remotely m-- You thought I was married this whole time?
