how does Jethro change emotionally in Across Five Aprils?From the first half of the book (before the war starts) and during + after the war, how...

One of the biggest changes that Jethro goes through is the
change in his attitude towards the war and towards issues in general outside of the
farm.  From his beginning as the innocent boy who has heard of various events around the
nation but never shown much interest, he changes to a relatively mature and inquisitive
young man.  As he learns more and more about the true nature of things, particularly the
war, he begins to make judgments about the right and wrong of things and be aware of how
events even far away events actually have deep effects on his life there on the
farm.
