Thanks to Robyn for spotting this well-faked photostrip, and giving us a description:
"In a 'sideways flash' the main character Jack (Matthew Fox) is trying to locate his son, David. Jack breaks into David's mother's home and searches through David's bedroom. On David's mirror is a photobooth strip of Jack and David together. It's there to show the viewers that the distance Jack is feeling from his teenage son was not always there."
