Oscar’s letter calls Yunior Count Fenris, an obscure yet powerful character from the science fiction book
Dune that Yunior has quoted at other times in the novel. Bene Gesserit Witch also comes from
Dune, referring to a female cult that has the power to control the whole world but uses that power for good. Oscar’s idea of a cure is ambiguous, possibly meaning a cure for the de León fukú, a cure for all Dominican people after Trujillo, or a cure for the unique problems of the children of immigrants.
