One thing is puzzling. Every time he goes to sleep, he wakes up to his other reality. One day he wakes up to a living son and a dead wife, working one case with a rookie partner, and visiting a confrontational shrink. The next day he wakes up to a living wife and a dead son, working a different case with his longtime partner, and visiting a nurturing shrink. Doesn't anybody in either reality notice that this guy is around only every other day?
