Ice

With Vaughn and Dixon covering, Syd tries to buy a bio-weapon called Ice 5
from an American at a foreign bazaar. When thugs disrupt the deal, Syd
bolts with the man. As they're running, his leg snaps off. He's then shot -
and literally explodes.

Marshall later determines that the biological agent, which the man had
swallowed, actually "freeze-dried" him, crystallized him from the inside.
He worked as a relief worker in Montenegro hospital run by Fenton Keene,
who secretly developed Ice 5. Sloane wants the team to obtain a viable
sample of Ice 5.

At Syd's home, Nadia finds a photo of Irina holding a baby. Nadia asks
Sloane who the baby in the picture is. He dodges the question.

Syd visits the hospital as a representative of Omnifam and does the grunt
work, while Weiss and Nadia put together a list of potential buyers. A
patient comes in showing symptoms of Ice 5 infection but the nurse, Kyra
MacLane, says he was in a car accident and won't let Syd help treat him.

Vaughn, disguised as a priest with a black eye, flirts with MacLane and
convinces her to make confession. Fenton appears, tells Vaughn that he's
her brother and asks to see the man in the car accident. Meanwhile, Syd
swipes MacLane's card key and passes it to Dixon, who makes a copy and
gives it to Syd.

Syd searches the lab and finds 14 tanks of Ice 5. To her horror, she spies
Fenton testing it on human subjects. Weiss reports that they found a buyer
in Damascus. They find MacLane is really Fenton's sister, and that they're
both former IRA. Vaughn feels she can be turned and approaches her during
confession.

When they meet, MacLane says her brother has done awful things. With Syd
listening in, Vaughn tells MacLane that he's haunted by thoughts of his
former wife, whom he killed after she betrayed him. MacLane realizes
Vaughn is government. He tells her that he can protect her from her
brother should she turn on him.

MacLane takes Vaughn to the lab, where Fenton clobbers him. He's forces
MacLane to inject Ice 5 into Vaughn's eye. Syd enters and rescues Vaughn.
During the fight, Fenton stabs his sister by accident. She dies in
Vaughn's arms, but forgives him before passing.

Jack asks Nadia for the photograph. He said Irina told her she was holding
her niece. The next day, he recalls, he proposed. He says he chooses to
believe it's true, but says that everyone needs to find our own sense of
closure.

On the return flight, Syd, sensing a disconnect, tells Vaughn he can talk
to her whenever he wants
