How we cite our quotes:
ENGSTRAND. You wouldn't stop long with me, my girl. No such luck! If you knew how to play your cards, such a fine figure of a girl as you've grown in the last year or two – (1.82)
Engstrand has some "fatherly" advice for Regina: your beauty is not to be squandered. He encourages her to think strategically about using her gifts. But Engstrand doesn't have to tell Regina. She's already on it.
ENGSTRAND. Then never mind about marrying them. You can make it pay all the same. [More confidentially.] He – the Englishman – the man with the yacht – he came down with three hundred dollars, he did; and she wasn't a bit handsomer than you. (1.88)
We can't decide whether Engstrand says this to irritate Regina or to motivate her (he would really love for her to work at his brothel, after all). It's probably both.
REGINA. [Arranging an arm-chair beside the table.] Now, do sit down, Pastor Manders, and make yourself comfortable. [He sits down; she places a footstool under his feet.] There! Are you comfortable now, sir?
MANDERS. Thanks, thanks, extremely so. [Looks at her.] Do you know, Miss Engstrand, I positively believe you have grown since I last saw you. (1.112-113)
She leans over and then he says she's grown? Pastor Manders recognizes Regina's sexual attractiveness. She notices that he notices, and believes it may be a card she can play.
