Like Son, Like Father
Christie was very close to her Dad, who passed away 10 years ago. Her grief led her into dark places, from which she has since recovered.
In talking with her, I picked up on how much her son reminds her of her Dad. Thus, the idea of a shot taken from behind, with Christie and her son Jackson walking hand-in-hand, and him with a dirty rag tucked into his back pocket and wearing a ballcap, just like her Dad used to do.
