What conversation does Dan have with Dr. Madden in Act 2, Scene 14?

Dan says he realizes Madden can't reveal whether Diana is working with him, but asks whether she's all right. Madden says she's working on it, and offers to arrange for Dan to talk with someone himself. At first Dan refuses, but then gratefully says yes. As Dan and Madden talk, Gabe appears, singing, as Diana did, of hope and possibility.
