Final answer:
The facilitator may have had Betsy deliver the accusations to divert suspicion from Marissa by utilizing Betsy's perceived credibility and to manipulate the situation for strategic purposes.
Step-by-step explanation:
The facilitator may have made accusations through Betsy as a strategy to shift blame away from Marissa, who was herself not a reliable accuser due to being under suspicion.
The context for this scenario seems to involve a complex social interaction where Marissa, by accusing Savanna, is attempting to deflect attention from herself. Such behavior is reflective of certain narratives where characters leverage accusations as a means of self-preservation or manipulation.
It is also possible that the facilitator chose to make the accusations through Betsy because Betsy was perceived as more credible or as a more effective means to punish or control the actual culprit. Understanding the motivations and relationships of the characters involved can provide deeper insights into the dynamics at play.
