Answer: Jem turned Dill in, which is considered as a betrayal in children's world.
Step-by-step explanation:
To Kill a Mockingbird is a novel written by Harper Lee. One of the most important themes in this book is growing up. Scout and Jem, two of the main characters, gradually mature and become familiar with cruelty and inequality present in the adult world.
In Chapter 14, their friend Dill runs away from his family, and hides under Scout's bed. Jem realizes that turning Dill in is the right thing to do, as his family must be worried about him. In Scout's opinion, Jem broke the code of childhood, in which it is not allowed to 'rat' on one another. In adult world, however, one must determine what is right and what is wrong. By turning Dill in, Jem demonstrates his maturity and real concern for his friend.
