 As much as she loves Sister Bertrille, the Reverend Mother believes that the high winds of San Juan create an environment not suitable for Sister Bertrille. This is highlighted by the fact that Sister Bertrille flew threw a new stained-glass window with her errant flying. So the Reverend Mother makes the difficult decision to transfer her to another convent, possibly in Rome. As exciting as that may be, Sister Bertrille is devastated about leaving, and openly shows that. Her frequent bouts of tears are due to this, but she attributes it to her allergy to hibiscus flowers. Sister Bertrille asks that the Reverend Mother not tell the other sisters until just before her scheduled departure. But the sister does tell Carlos, who is also disheartened by the news, but would not dare question the Reverend Mother s decision. But Carlos works behind the scenes with the children of the convent to organize a protest to keep Sister Bertrille at San Tanco. Sister Ana overhears the news of Sister Bertrille s departure, thinking that Sister Bertrille is dying. So the sisters treat her with kid gloves. They also see the Reverend Mother is treating Sister Bertrille with her regular sternness, the sisters thinking her cold-hearted in light of Sister Bertrille s imminent  passing . Thus the sisters embark on a cold shoulder campaign toward the Reverend Mother, who thinks it was orchestrated by Sister Bertrille as defiance against the transfer. This strengthens Reverend Mother s resolve to transfer her. The misunderstanding becomes known and is resolved, and everyone becomes clear as to Sister Bertrille s real fate. The sisters also find out about Carlos  campaign; the sisters suggest to him that that may not be the best approach to take with the Reverend Mother, and Carlos calls off the campaign. However, the campaign takes on a life of its own extending to the people of the community; this shows the Reverend Mother what a truly profound effect Sister Bertrille has had in her short time at San Tanco. The sister can stay.
