Bruno heller is playing politics.
He said he didnt wanna rush the red john reveal
He made a fake reveal episode to get viewers in order for the show to NOT get cancelled.
Brilliant move.
By doing this he buys more time to keep the mentalist from being cancelled mid season.
This way he doesn't have to rush anything he can reveal and hopefully kill
Red john at the end of this season. Thats why red rigsby is leaving the show because he being red john will be killed
