how does elie's relationship with his father change

Early in the book, they are very close. As time wears on in the camp both see their reality, God.....differently. Still Elie always loved his dad.

Oops sorry, they were not close in chapters 1 and two. Eli's father is a leader in the community and too busy for Eli. Through the horrors of the camp they stick by each other and understand one another better. THey see their world differently but Eli still loves his dad.
