Based on the lie Carlos told her, Sister Bertrille tells them that he is coming to bring them and their entire family to live in one of Carlos  houses in San Tanco. When she finds Carlos at Elana s, Sister Bertrille learns the truth about Carlos  trip to Culebra and Carlos in turn learns about the expectation that his aunt and uncle have about going to live in San Tanco.

Carlos ultimately is happy to have his family move to San Tanco when they remind him what wonderful things they did for him when he was a child.
