Simon Baker is happy, "really happy," the star of The Mentalist told TV Guide during a recent set visit by that publication.

During the interview, the actor said he doesn't wanna "touch" the show, in terms of changing the dynamic that has led The Mentalist to the top of television's ratings.

Among the series storylines that will therefore remain the same, Baker confirmed:

• Red John, the killer, won't be caught for awhile;
• The series will not depart from its format, in which almost every case is resolved within one episode;
• Baker's dynamic with Robin Tunney, who plays straight woman to his wild card, will remain the same.

Simon Baker and Robin Tunney make for a great team on The Mentalist.
