Kiera MacLaine: Forgiveness is a tricky thing, isn't it?
Modell: My bird is missing.
Weiss: It's "I've lost my canary."
Jack: (to Nadia) Irina told me years ago that this is a picture of her holding her niece. She told me that holding this baby filled her with a longing and a hope to have children of her own. The next day I asked Irina to marry me; I wanted my child to be loved like the baby in this photograph. Of course, her story could have been a total fabrication, another one of her countless lies designed to draw me in. But I choose to believe it was truth. When we had Sydney, Irina held her in this exact same way, and I can only imagine that she did the same with you. So for me, I choose to believe. But than I suppose each of us needs to find out own sense of closure.
Fintan Keene: My sister may look like an angel but her heart is as black as yours and mine.
Vaughn: I was married for a short time... The woman I was married to betrayed me, she betrayed alot of people. And when I found out what she'd done I let my hate for her consume me, I began to wish the woman I loved was dead. I woke up every day imagining how I'd do it, what was the best way, what was the most efficient way. It's all I wanted. That woman was evil and deserved to be punished and so I killed her. And although that woman was the worst kind of evil I also know that killing her was wrong. I don't sleep much, I can't. I can't close my eyes without seeing it, that moment, the look on her face. She won't leave me. She won't.
Jack: Is something on your mind Agent Vaughn.
Vaughn: (hesitant) No, not really. I'm not very sleeping well.
Jack: It's Lauren, isn't it.
Vaughn: I think I see her sometimes; I thought I saw her in the market in Algeria. Did that ever happen with you?
Jack: Do I have visions of Lauren?
Vaughn: I don't know that many people who killed the woman they were married to. I was just wondering if that's what happens.
Jack: It did, now it doesn't.
Vaughn: It's not everyday you see a guy shatter into a million pieces.
When Nadia is going through the pictures, the second picture is Jennifer Garner (with the glases), and her real life sister, Susannah.
In Montenegran, the light switches flip up, like American light switches, but in Montenegran, the light switches push down to turn on.
Sloane: He called it Ice 5, and offered it to the Agency for ten thousand dollars.
Cat's Cradle, a book by Kut Vonnegut, mentions an ice, called "ice nine" which could crystalize water.
