The writing of this series is unraveling. Characters are now frighteningly one dimensional. The plot is accelerating into silliness that makes the commercials look good. So, let's "go with the flow": Jane is a multiple personality who's "dark side" is hidden from his "grinning side." As a con-artist mentalist, he "hypnotizes" the pawns of Red John to thicken the plot but all are mentally "under" his control. Barf!
