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)
A placebo is anything that seems to be a "real" medical treatment -- but isn't. It could be a pill, a shot, or some other type of "fake" treatment. What all placebos have in common is that they do not contain an active substance meant to affect health.
