JEANINE:—Let’s be honest, Felix; this man is full of love—I think you realize that now, don’t you; all he is is love. But we aren’t. I’m not and neither are you. You’ve killed too many of us to forget so quickly.
In this story, Jack, or Charley, is implied to be the second coming of Jesus Christ. However, Jeanine and Felix believe in this stranger only when they realize that he is “full of love.” This is parallel to Jesus and God, often depicted as the epitome of love and caring. Although Jack and Charley remain ambiguous throughout the story and it never confirmed that this stranger is God/Jesus, Jeanine finds hope in her life through her love for him. However, in the end, she too accepts his crucifixion, putting her devotion in question.
