if the description of the bragg house is symbolic of the bragg character, what might it show?

Randy lives in his family home by himself, a place much larger than he needs for just himself. He also lives off of his trust fund; his life is consumed by searching for a parakeet. When his brother writes that he's sending his family to stay with Randy because he has more than enough room to take care of everyone, he signs "Alas Babylon," in reference to sermons given by Pastor Henry when they were boys. The phrase is a code between the two meaning a disaster is coming, which in this case is war.
