At APO, Sloane says that money was deposited into the account by Boris Tambor, an oil magnate who moonlights as an arms dealer. He's currently in Monte Carlo. Jack says he sits at a high stakes poker table every night at 9. Their mission is to get into his suite, find out where he keeps the black Thorine and how he plans to move it.

Syd confides to Dixon that she may not be able to work with Sloane. Dixon says he dreams of his dead wife Diane every night; she tells him to do the right thing. That's how he makes peace with Sloane -- he doesn't ignore the past, but he makes the right decision today.

As they shoot targets at a firing range, Syd tells Nadia that she needed to know her mother and so understands Nadia's desire to know Sloane.

In Monte Carlo, Syd inserts a micro camera into the suite and gets a visual on Tambor, who's watching a soccer match - not going to the gaming table. Nadia and Syd notice perfume, a purse, magazines. They realize he's got a girlfriend. Deducing that the woman is bored, pissed off because she's being ignored and sitting in the bar, they see their opening.

Dressed up to party, Nadia and Syd identify the girlfriend through her perfume. They befriend the woman; she takes them up to the room and past security. Syd clones his PDA hard drive while Nadia chats up Tambor.

In LA, Sloane is angry at them for taking risks. Syd gets indignant at what he deems "unacceptable." Everywhere she looks, she says, she's reminded of Francie and Danny. Marshall has broken the hard drive's encryption and finds out that Tambor will sell the vial on his yacht, Argento, which is sailing in Turkish waters in the Black Sea. It's stored in a safe within a safe in a cabin below deck. Marshall gives Syd a device that will allow her to read the safe's combination through his clothes.

Jack lobbies for Sloane to allow Syd and Nadia to work together again. They swim to the yacht and sneak on board. Syd uses the combination reader while Tambor makes the deal. Sloane recognizes the buyer as Leo Orissa, the head of a Russian crime syndicate. Nadia opens the safe - revealing eight canisters of Black Thorine.

Orissa ambushes Tambor, whose girlfriend turns on him. Tambor is killed as Syd and Nadia escape to the water. Sloane tells Syd he has to trust him and advises her to go back on board. Confronting Orissa, Syd says she works for Arvin Sloane, which sends fear into the man. Syd catalogues Sloane's depravity. Orissa offers up the location of the lab. Meanwhile, Nadia disposes of Orissa's thugs. The lab, Orissa says, is in the Ukraine. Tambor's girlfriend shoots Orissa and fights Syd. With an assist from Nadia, Syd kills her.

Nadia tells syd she's always been alone. Now she's glad to work on a team. Sloane assumes Syd wants a transfer. Syd says she will never forgive him. "I'll see you tomorrow," she says.
