Based on the excerpt from “Big Water,” it can be inferred that Henry and Eva have provided significant support and protection for both Daniel and the narrator. The mention of their actions indicates that they have taken on a nurturing role, likely offering guidance and assistance during a challenging time. For instance, if the passage describes their reassurance in a moment of uncertainty or danger, it would illustrate their commitment to the well-being of Daniel and the narrator. This implies that Henry and Eva's involvement is not just practical but also emotional, suggesting a deep bond and sense of responsibility between them.
