When was this quote from in Bioshock Infinite?

I just finished playing this game and I love the quotes from the Lutece Twins. I found this quote from here:

Robert Lutece: I told you they'd come.

Rosalind Lutece: No, you didn't.

Robert Lutece: Right. I was going to tell you they'd come.

Rosalind Lutece: But you didn't.

Robert Lutece: But I don't.

Rosalind Lutece: You sure that's right?

Robert Lutece: I was going to have told you they'd come?

Rosalind Lutece: No.

Robert Lutece: The subjunctive?

Rosalind Lutece: That's not the subjunctive.

Robert Lutece: I don't think the syntax has being invented yet.

Rosalind Lutece: It would have had to have had been.

Robert Lutece: Had to have... had... been? That can't be right.

I remember this quote from the game, but I can't figure out when it was said in the game. Can anyone tell me what chapter or general area it was told?

In Emporia, after Booker awakens in the crashed ship, we find the Lutece Twins plinking on a piano. During the cable car to board the car to Emporia proper, you will overhear that amusing conversation between the twins.
