- Michael Vaughn: You're so beautiful.
- Sydney Bristow: [after Vaughn kisses her] Dinner's ready.
- Michael Vaughn: You do have an oven you know, we can reheat.
- Sydney Bristow: About last night...
- Michael Vaughn: Is this going to be about Alice?
- Sydney Bristow: I know it's complicated...
- Michael Vaughn: We're not together anymore.
- Sydney Bristow: Since when?
- Michael Vaughn: Since this morning. The truth is, we've been over for a long time.
- Sydney Bristow: I was thinking... I can actually go to the CIA through the front door.
- Michael Vaughn: And I can actually give you a ride.
- C.I.A. Agent James L. Lennox: I could've sworn you were a blonde.
- Sydney Bristow: I was. My hair's usually brown. Hard to keep track.
- Sydney Bristow: How is this possible without obvious scarring?
- Jack Bristow: The procedure isn't surgical. A patient's genetic code is altered to reshape their physical attributes.
- Sydney Bristow: Is it reversible?
- Jack Bristow: It's unclear. It only works on people of a certain genetic disposition and the recipient must be induced into a comatose state for several days while their cells regenerate. The data indicates the only way to distinguish the real person from the double is by an ocular scan. A flaw in the iris was deliberately built into the procedure to tell them apart.
- C.I.A. Agent James L. Lennox: Emma used to say that she had spent so much of her life pretending to be other people that she was afraid she might disappear. And I have been sitting here trying to remember all her aliases and you're right. It's hard to keep track.
- Sydney Bristow: I lost my fiance last year and I know we're trained to compartmentalize things that hurt too much but I still haven't been able to do that. As hard as it is, I would rather feel it than to not feel anything.
- Jack Bristow: We've decrypted the specs on Project Helix that you and Vaughn obtained. The data describes a breakthrough in next-generation molecular gene therapy. It refers to a new procedure whereby a patient's face and body are reshaped to identically resemble someone else. Agent Lennox was the first test subject to be doubled.
- C.I.A. Agent James L. Lennox: I'm not the only one who's been doubled.
- Sydney Bristow: Who else?
- C.I.A. Agent James L. Lennox: It doesn't say.
- Sydney Bristow: [to Lennox] One thing about my fiance... I was lucky to have known him for as long as I did.
- Eric Weiss: So, in a case like this, we start by digitizing all the news coverage that covered the bombing. You, uh, you like Italian food?
- Christine Phillips: I have a boyfriend.
- Eric Weiss: [Weiss looks up as Vaughn walks in the room] Yeah, me too.
