CIA Safe House. St. Petersburg. Vaughn, Katya, and Syd are hiding out. Vaughn's killing time by yammering at Weiss about how Katya saw Sark and Moronen on a surveillance feed and how they acquired a bottle of Rambaldi Green Goo™. It should be noted that Vaughn is almost irrationally angry at this point, and that he orders Weiss to get that satellite retasked because he wants them FOUND, dammit! Vaughn walks off to yell at Weiss some more as Katya and Syd get acquainted with each other. Syd announces that Spy Daddy's sending a helicopter to pick them up, and then she takes a seat across from her aunt. "What were you doing at the laboratory?" she asks. Katya just ya-yas that her people got intelligence that Sloane was going to infiltrate the lab, but they got there too late to intercept him. "If Sloane is after the fluid," she says, "he must be very close to finding Nadia." Syd chooses not to tell Katya that Nadia's been located already. Instead, she mentions that in the video files they found, Nadia was drawing something, what Syd assumes was Rambaldi's message. "If the message was already relayed," asks Syd, "why is she valuable?" Well, that's easy, Syd: Nadia was taken away from the lab before she could finish the message.
"My father took her," says Vengeful Vaughn, returning from his emasculation of Weiss. "He hid her away to keep her safe from people who were trying to use her." Katya's all, you trying to imply something, Commando Ken Doll? Vaughn's all, nah, not really. Except I'm curious as to why you're suddenly so eager to find your long-lost niece. Because I really don't think you're trying to give her that pearl bracelet that Grammy Derevko left her in her will. Katya's all, yeah, you might wanna bring the tone down a notch, Soldier Boy. I've risked my life and compromised my position with the SVR in order to save your two sorry asses from certain execution. So how 'bout a little gratitude here?
And this scene? It just keeps going and going and going…Katya tells them that she is, in fact, working with Irina, and that when Irina returned to Russia, way back in the days after she'd faked her death, she was immediately apprehended. Her loyalties were questionable. After a few months in jail, she gave birth to a wittle baby girl. "That girl was one day old when she was taken away from your mother," says Katya. "The only reason I joined the Russian secret service was to help Irina find her younger daughter." So, yeah, for years they couldn't find her, every lead went cold, and then recently, they got word that her father, Sloane, was also looking for her. Syd totally indicates that she knows something, and Katya asks what it is. Syd spills it that Sloane already has Nadia. Katya looks suitably freaked out by this knowledge.
