Back in the palace, Bolingbroke asks why he hasn't come to see his sister. He's been separated from her for a long time, and she's had a stroke, so he's alienated from her. He wants to thank her for the medicine she gave him for his illness, but she won't tell him what she wants. She wants to know if the coal mine that she found is still there, and if the emperor is there. He says he'll reward her if she comes closer, but he doesn't want to make any money off of it. He tells her to walk to the emperor's house and tell him the good news. He also tells her that they've decided to trade horses between the three of them, and that the princess is going to be his wife. He gives her the task of convincing the two princes of Yuheg to agree to the deal.
