The team searches for Abby Horton (LAURA JORDAN), a promising young artist who secretly photographed strangers who were experiencing intense personal moments and then later painted them. As Samantha and Elena survey Abby's ransacked studio, they wonder if she could have fallen prey to someone who was outraged to discover that she had immortalized their private experience. The team soon learns from Lucas Blumenthal (PETER PAIGE - "Queer as Folk"), an art gallery owner who had opened an exhibit of Abby's paintings right before her disappearance, that Abby was recently confronted by an angry male who was depicted in one of her paintings.
