David Lythberg may be Emily's failure, but he's also God's prodigal son.  Actively living with Emily on the streets of Mobile, Alabama for a few years, David's life took a different turn after her sudden and tragic death.  He walked home to Chicago.  He let himself be guided to his mom who was a missionary in Ghana, just knocked on a strange door and she answered.  He prays that you will be kind when you see a gutter punk on the side of the road.
