How would the book be different without Dill?

I think Dill brought Jem and Scout together. His character enriches the novel and provides us with interactions that solidify the way we see Scout and Jem change throughout the course of the novel. Dill is not a mainstay, he moves in and out of the story and at times allows us a breath of fresh air. He's funny, outlandish, tender and empathetic. One of the most beautiful scenes in the novel is his quick exit from the courthouse, which is accompanied by a wealth of tears..... innocent tears.
