Question: why is jem so inconsistent and moody?
Answer: Why is Jem so "inconsistent and moody"? Jem is now 12 years old; he is growing up physically and mentally, which makes him difficult to live with. Why wasn't Dill able to come to Maycomb this summer? He had "a new father" and would have to stay in Meridian because they planned to build a fishing boat.
