How does Jem impact Scout. This is a very big question. As her big brother, Jem is Scout’s “hero.” Again and again we see Scout wanting to be as “tough” as he is. When playing with him and Dill, Scout wants to be “one of the guys.” All Jem has to do is call Scout “Miss Priss,” and Scout is ready to do whatever her brother wants. Several times we hear Jem tell Scout “not to act like a girl.” She thinks he knows just about everything, as we see, for example, when she is sure that Boo Radley was stuffed up the chimney by his father “because Jem” said so (43). He also gives her possible interpretations of life that she can accept or reject, such as when he concludes (after the trial) that Boo doesn’t come out of his house because he doesn’t particularly like the world outside. And then, of course, Jem tries to save the life of his sister when she is attacked at the end of the novel.
