While The Mentalist reorients its plot back to a crime of the week format, series creator Bruno Heller cautions fans that upcoming investigations won't be of the same variety as those in the Red John era.

"We will be returning, eventually, to crime solving," Heller said, according to Collider. "Not necessarily the same kind of crime solving, but yeah. We could make it a weekly elimination dance contest. Simon Baker would be really good at that. He wouldn't win the singing contest because I would win that, but he would definitely win the dancing."
