Obviously, our Emily was pregnant before they filmed this episode, so what else can they do? But we have had so much plot made tiresome by focus on reproduction. I suppose there will be a whole hour of a show about forensic anthropology having all the character goo gooing over the birth. Anyway, we have the murder of a man who was a big time gambler. Booth goes to gambler's anonymous. But his ego steps in and he insists on going undercover. The man in question won large amounts, yet there was no money with the body. So it had to be a player. Of course, our intrepid FBI guy throws out some negative possibilities at the conclusion.
