- Part 1 - High School Blues Evan and Alexia had been happily married for seven years and had a delightful five-year-old son named Ryan. One day, while going through his old high school biology textbook, Evan stumbled on some troubling information. In the section on the genetics of eye color, he read that two blue-eyed parents cannot produce a brown-eyed child. This was disturbing to him because both he and Alexia had blue eyes, but Ryan had brown eyes. He and Alexia were very much in love and Evan didn't believe his wife had been unfaithful. Puzzled, he questioned his wife, who confirmed she had been faithful to him. Evan had known Alexia long enough to recognize when she was lying and detected nothing but honesty in her response.
