Because you should read it again and answer it yourself
The protagonists is Scout but following close behind her is her father. Scout is a curious girl and questions all that her dad says. This gives us, the readers, a chance to really immerse ourselves into the story as we follow it alongside Scout. We further connect with her as we are "on the same boat" as her, in the sense that we only discover things as she does in the book, when she does. There is no dramatic irony ( not that i remember)
<span>It heightens the sense of loss in the poem.</span>
