Answer:
Ruth convinces Robert to stay on the farm rather than leave on his planned trip with his uncle. This changes the direction of the plot because rather than following his dream of travel, Robert is staying on the farm where he will likely be unhappy.

RUTH. (in a soft murmur) Yes. Our very own star. (They stand for a moment looking up at it, their arms around each other. Then RUTH takes his hand again and starts to lead him away) Come, Rob, let’s go. (His eyes are fixed again on the horizon as he half turns to follow her. RUTH urges) We’ll be late for supper, Rob.
ROBERT. (shakes his head impatiently, as though he were throwing off some disturbing thought—with a laugh) All right. We’ll run then. Come on! (They run off laughing as The Curtain Falls)
