Vera Farmiga's Norma Bates is already running out of time as Norman will be a full-blown psychopath when "Bates Motel" returns for season 4. Norma could even be her son's next victim as showrunner hints that her death will help develop the story.

A&E's hit drama thriller is aiming for a darker season now that Freddie Highmore's Norman Bates is nearing the state of his counterpart in Alfred Hitchcock's classic film "Psycho."

We previously reported the things that the fans can expect in "Bates Motel" season 4, which teases the blooming relationship of Dylan, played by Max Thieriot and Emma, played by Olivia Cooke. Nestor Carbonell's Sheriff Romero and Norma will also have a chance to take their relationship to the next level in the upcoming season.

In his interview with Entertainment Weekly, Kerry Ehrin, executive producer of the show, hints one of the anticipated episodes in the series that will see the death of Norma Bates. Now that the show only has 20 episodes left, Ehrin admits that it will be happening somewhere in the middle of the remaining 20 episodes since Norma's death will help develop the Norman arc.

"I feel like that could happen, honestly, at any point. It could happen in any episode from now until the end of the series!" Ehrin added.

Surely before that happens, we will still see more of the unstable Norma, who often losses it when it comes to protecting her demented son. Even Vera Farmiga revealed that she enjoys seeing her character go nuts from time to time during her interview with TheWrap.

"The biggest hoot is and always will be presenting Norma's freak-outs. At least once a season, excrement hits the oscillating air device for Norma and she goes postal," the actress said.

She also explained the biggest difference of their show from other thriller TV shows that also has a cult following like theirs.

"What sets our thriller apart from others on TV right now is that we are firmly rooted in reality," Farmiga said. She then added, "There is nothing mystical, fantastical, supernatural, spectral or otherworldly in our show. We explore the darkness of the human condition." 

"Bates Motel" season 4 might finally see the death of Norma despite her unconditional love for her son and her efforts to make him well. Her death will ultimately help the story to progress now that there are only 2 seasons left for the A&E hit series.
