What news does Sammi have for Miranda when she visits her in Chapters Seven and Eight?

Sammi stops over to tell Miranda that she is leaving with a much older man, who has promised to protect her. Sammi's parents agree that it is a good idea, since she is more likely to survive with him. They are planning on heading south, where they have heard that conditions are better. This is a shock for Miranda, who knows she
will probably never see Sammi again.
