Mary Dittrich (the girlfriend of the photographer Robert Dittrich): Relax. It's not like he saw us together.
Angela Darmody (the wife of Jimmy Darmody): Nucky Thompson didn't get where he is by being native. That look on his face -- He knows something's amiss.
Mary: So he knows. And then what?
Angela: Well, he could stop giving me money... You're so good. I depond on this man.
Mary: What about Jimmy?
Angela: I would have thought he'd send something. If not for me, for Tommy.
Mary: You just may have to get a job, my sweet.
Angela: I know... Anything from that art dealer in New York?
Mary: No. But Robert's friend Jonathan is coming in town to look at some real estate. He works at Washington Square Gallery in Greenwich Village. He's agreed to assess your work.
Angela: Greenwich Village? Can you imagine?
Mary: It's everything you've ever heard it is.
I know all the words, but I have difficulties in grammatical analysis.
I think "you've ever heard" is an attributive clause that modifies "everything", so the sentence can be reduced as "It's everything it is". And what is "It's everything it is"?
