Fans of the show "Bates Motel" were left on the edge of their seats during the last episode of season 3 of the A&E thriller. Showrunner Carlton Cuse has now promised to reveal a whole new side of Norman Bates in the next season.

Since it began airing in 2013, "Bates Motel" has developed a steady social media following. The series is a contemporary adaption that chronicles the early stages of Norman Bates' life, before the events of Alfred Hitchcock's "Psycho".

At the end of season 3, Norma's world starts to unravel and fearing that she will no longer be able to take care of her son, she meets with an asylum administrator to admit Norman. However, the asylum's high admission fees puts paid to her plan. Norma tells her son the bad news, but Norman now plans to leave town with Bradley. Norma tries to stop Norman, but he escapes. Norman's hallucination catches up with him and he envisions his mother while he is with Bradley, and then kills him as Norma in a fit of delusion.

Even if it is early to tell, [Carlton], Cuse has dropped hints about the possible storylines for the next season.

"The promise of Season 4 is Norman unleashed. Season 3, the journey was about Norman becoming aware of his pathology, in that he is capable of blacking out and that he does some less desirable things when he blacks out. That's where we start the season. By the end of the season, Norman is moving from one persona to the other without any real cognition of that. And that is the scary evolution. Now that this character is freely jumping in and out of personas, that's going to be really compelling. The question is, what can Norma do to save her son as he descends further into his disease. That's really the question of Season 4," said Cuse in an interview with Calgary Herald.

There has been no announcement yet by A&E about season 4, but fans are excited at the thought of seeing their favorite psychopath return to the small screen.
