The story of why Barry got into forensic science wasn't a very happy one, but the whole point of their date was getting to know each other, so he figured he may as well share. "Well, my mother was killed when I was nine," he said. "I got into forensic science so that I could try to figure out who was responsible."
He decided not to mention the part where his dad was convicted and spent years in jail for a crime he didn't commit because no one believed a traumatized nine year old's version of events.
