Final answer:
The relationship between Pilar and Olivia, as well as what may have fractured it, cannot be inferred from the provided text, which lacks details about their interactions.
Step-by-step explanation:
The nature of the kind of relationship that Pilar and Olivia had prior to the events of the story is not explicitly described within the provided text. It is impossible to determine from the given information whether they were friends, relatives, or connected in some other way. Similarly, there is no evidence to reference when describing what may have fractured their relationship. Since the provided context is vague and does not discuss Pilar and Olivia or their relationship, we cannot make any valid inferences about the specifics of their past interactions or what might have led to any discord between them.
