I thought back to the other cryptic phrase that Mama G had uttered that day: "Beware the priest whose magic ..." Certainly we had to be wary of Domingo Vargas. But had Mama G been referring to him in her warning—or to someone else? To Gus, for example. Also a sacerdote, but of another religion. Also quite capable of working magic. And also, by his own admission, quite capable of betrayal.
