Define healthy? Define normal? If you look at the facts on paper, the answer would most certainly be not very likely. Yet, in spite of his growing up years, Kellen accomplished more than anyone expected him to to begin with. He owned a home, owned a legitimate business, and cared deeply that Wavy was hungry, the house dirty, and that she was at risk in school. And Wavy, raised in a filthy home by a drug addicted mother and an absent father... She continued her education. She never gave up on Kellen, and she searched for her brother to the ends of the earth and found him! The fact that these two continued to love, support, and depend on one another when the rest of the world crapped on them over and over leads me to believe that they have a stronger relationship than most "normal" people.
