When I look back, I can see now that my relationship with Katherine followed the classic example of a catfishing/social-engineering attack. Except in this case, I had been catfishing both Katherine and myself. It was not what I planned, and it pains me to illustrate the points, those that make me look both like the villain and the fool, but when a breach has been detected, one of the most important steps is gathering all artifacts and details in order to analyze the origin and impact of the attack.
He ties together the concept of online catfishing (putting out a false persona) with his relationship with Katherine.
