In chapter 9 , what did Dedé's sisters ask her to do? And what did she say?

In the fall, Patria asked if she could bury some boxes in the cacao fields, but Jaimito refused, and Dede has been avoiding her sisters ever since. Now, they report that "something big" is about to happen in less than three weeks, and Maria Teresa asks her to join their cell. Dede silently decides to leave Jaimito the next Sunday and attend the meeting with her sisters.
