A Guy：Luisa, wa-wait, c'mon, c'mon, I'm telling you,I'm telling ya baby, you can't leave me. It's a...you know, it's a past life thing or a future life thing,but ya know, it's you and me...
Luisa：Look. For the last hour, all I could think about wasthrowing you off your balcony.
A Guy：I mean, who the hell do you think you are?You write a bullshit column for a fuckin' rag.
Luisa：Elevator!Thank you.Nice to know the age of chivalry isn't dead.
Rufus：No bones broken, I think.
Luisa：Wait, wait. No, no. You sit... you sit, you sit. Let me see.Great. Power outage.Perfect end to a perfect day.
Rufus：Still glad the age of chivalry isn't dead?
Luisa：I still rather be right here than back up there.
Rufus：Guess Mr. Ganga isn't everyone's cup of tea.
Luisa：Guys like that are just an occupational hazard.
Rufus：You were interviewing him?
Luisa：Yeah, for Spyglass Magazine.Luisa Rey.
Rufus：Rufus Sixsmith.Rey...You wouldn't happen to be relatedto the journalist, Lester Rey?
Luisa：Yeah. He was my father.

Luisa：It's hot.And we're still here.
Rufus：That's a very peculiar birthmark.
Luisa：Yeah, my little comet.My mother swore it was cancer.She wanted me to get it removed, butI don't know, I kinda like it.
Rufus：I knew someone who had a birthmark that wassimilar to that.
Luisa：Really?Who was it?
Rufus：Someone I cared about very much.A, uh... A hypothetical question for you, Miss Rey.As a journalist,what price would you pay to protect a source?
Luisa：If it came to that... yes.
Rufus：Would you be prepared tocompromise your safety?
Rufus：Taxi!You sure you don't need a cab?
