Syd, Dixon and Marshall are to observe the meet and bring her in if the opportunity exists. At lunch with Nadia, Syd talks about past encounters with Anna. Nadia says she saw something awful when she was connected to Rambaldi last year -- She had a vision that she and Syd were aiming guns at each other. She pulled the trigger and shot Syd, she says, who seemed to expect it.

Syd takes a call - it's from Anna, who's actually sitting behind Nadia. She kidnaps Nadia and demands that Syd pose as her in Brussels for the meeting with Sabine.

In Brussel, Sabine says he wants to get his money's worth before he gives her the item. He tells Syd to kill Willem Karg, who's in a hotel bar, photograph the body as evidence and bring back his right index finger. If she's not back in 40 minutes, she won't get the package.

Syd poses as a prostitute and lures Karg to go up to his room - where Vaughn and Dixon wait. They cut off his finger to save his life. She presents it to Sabine; he gives her the "last remaining sample."

Anna has her thug Mr. Turner brand Nadia with the Rambaldi symbol.

Marshall identifies the sample as the Dante Compound, a rare putty that when mixed with V/X gas and other nerve agents, will mutates them. Marshall believes Anna works for the Cadmus Revolutionary Front, an offshoot of the Covenant. They've been trying to acquire the compound for a year to make a chemical bomb. He suggests they talk to Sark.

Sydney doesn't think they should follow through on a plan to give Anna a replica of the Dante Compound because she may kill Nadia. Sloane says Anna won't kill Nadia - he says it's not her destiny. Syd realizes this is about Rambaldi. Jack agrees that Syd should meet with Anna.

They meet in a Beverly Hills boutique. Syd gives her the compound. Anna gives syd a remote car key and tells her to go to the 4th floor of a parking structure across the street. Anna threatens Syd, who starts a knock-down, drag-out brawl that ends in a virtual stalemate. Realizing that they're getting nowhere, they make the exchange. Syd finds Nadia locked in a car trunk.

Vaughn visits Sark in the federal pen. Sark asks if he killed Lauren because of espionage or infidelity. Vaughn hits him and asks why the CRF has made repeated attempts to contact him. When Sark goes silent, Vaughn has him shipped to Alder Penitentiary, where he is to spend all his days in dark solitary confinement.

Syd returns with Nadia. The surgeon says they can fix the brand. Nadia relates Anna says that she and Syd will be torn apart. Syd explains that according to their mother, the outermarkings of the Rambaldi symbol are her two daughters, the center is the object over which they'll do grave battle with each other. Only one of the daughters will survive. Syd says some of these predictions have come true, but that she doesn't believe in it. The people who do, she says, are dangerous.

Jack injects Sark with a tracking device (and explosive) while he sleeps in prison. As Sark is transferred, the vehicle is attacked. - it's a set-up. And a man helps Sark escape.

Syd hears chatter about a meeting between the CRF and an administrator of a Russian chemical facility named Vorich. Syd thinks Anna may be there. Jack tells her to take Nadia for surveillance only. If Vorich is there, he may have a sample of V/X. Sloane is afraid that if Syd and Nadia go on the mission together and Anna has her way, only one will return. Marshall tracks Sark to Johannesburg.

In Johannesburg, the team raids what they think is CRF headquarters, only to find Sark in an empty room guzzling champagne. He agrees to locate CRF leadership in return for something.

In Estonia, Nadia and Syd find Vorich, who's quickly killed by Anna. Nadia battles Mr. Turner as Syd chases Anna. The dude falls on his knife, Nadia twists it until he reveals in his dying breath why the CRF is assembling the bomb. Syd think she's cornered Anna, but it turns out to be Nadia. Anna then shoots Nadia in the back. She falls as the life ebbs from her.
