Why do The Twins grant a temporary restraining order against Denny?

The correct choice highlights a pivotal moment in the narrative where The Twins, having concerns about Denny's character and suitability as a guardian, react to information they receive about him. Annika's claim that Denny is a sex offender serves as a catalyst for their decision to seek a temporary restraining order. This assertion raises severe questions about Denny's integrity and fitness, leading The Twins to take protective measures regarding Zoë.

The gravity of such a claim cannot be understated, as it reflects societal and legal concerns over children's welfare, especially in custody contexts. Whether or not the claim holds truth, The Twins' action indicates their deep-seated fears about Denny's potential threat to Zoë's safety, which drives their motivations throughout the story.

The other options don't align with the specifics of the narrative; they either misinterpret the motivations behind The Twins' actions or distract from the core issue presented by Annika’s allegation. By focusing on the serious implications of the accusation, the correct answer encapsulates the tension and stakes involved in Denny's struggle during this part of the story.
