Summary
Analysis
Sidney writes Juliet and says that she's clearly in love with Dawsey. He asks if he can visit on the 13th. Juliet sends Sidney a telegram in reply, admits that he's right, and says she's thrilled to see him.
It's worth noting that Dawsey hasn't tried to change Juliet at all and has actively supported her career—he'd be a much better partner than Mark.
