Alias

(After SD-6's fall) Sydney: I was thinking... (With a smug smile) I can actually go to the CIA through the front door. Vaughn: And I can actually give you a ride. (Smiles too)

(Sydney walks into the safe house and finds it trashed, and Agent Lennox drunk) Agent Lennox: Beware of the grieving man and his bottle.

Sydney: How is this possible without obvious scarring? Jack: The procedure isn't surgical. A patient's genetic code is altered to reshape their physical attributes. Sydney: Is it reversible? Jack: 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.

Jack: (to Sydney) 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.

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: I lost my fiancé 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.

Sydney: About last night... Vaughn: Is this going to be about Alice? Sydney: I know it's complicated... Vaughn: We're not together anymore. Sydney: Since when? Vaughn: Since this morning. The truth is, we've been over for a long time.

Sydney: One thing about my fiancé... I was lucky to have known him for as long as I did.

Lennox: I could've sworn you were a blonde. Sydney: I was. My hair's usually brown. Hard to keep track.
