With whom does Dede reconnect at a reception in honor of her sisters? what does he tell her about their "Nightmare" past?

She ran into Lio and his wife at a reception in honor of her sisters, and they caught up intensely about the past. She remembers this as she stands overhearing the conversation between Minou and Doroteo, then goes inside to tuck Minou in. Then she falls asleep herself, but it is different that night; she does not hear the spirits of her sisters running through the house. Instead, "all I hear is my own breathing and the blessed silence of those cool, clear nights under the anacahuita tree before anyone breathes a word of the future."
