'Bates Motel' season 5 spoilers, plot news: Norma to still exist in Norman's brain despite shocking death in season 4, Marion Crane to be introduced

Thriller drama "Bates Motel" ended its fourth season last Monday, and viewers still can't get over the shocking death of leading lady Norma Bates (Vera Farmiga). The show will have its fifth and last season next year, but as seen in the final episode's closing sequence, the popular TV matriarch is not going anywhere.

"Bates Motel" serves as a prequel to the 1960s cult-classic "Psycho" by Alfred Hitchcock, and in the film, Norma makes her way to the far reaches of her son's brain. Executive producers Kerry Ehrin and Carlton Cuse confirmed this plot detail in an interview with TV Line. "She's existing now in Norman's brain," Cuse explained. "In the original 'Psycho' you don't really know anything about Norma Bates. You just know that she's a corpse, and you imagine that she was this shrew of a woman who berated her son into becoming crazy. But we reimagined their relationship as this complex, intense, co-dependent love story. And that relationship continues very much in Season 5. It just has a different dimension, which is that she's dead. [Laughs] But it's not the end of the story."

The huge plot twist in the finale will surely change the tone of season 5, and the showrunners couldn't agree more. "Season five is about the ways in which our show does and more specifically does not intersect with the events of Psycho," Cuse told The Hollywood Reporter. He stressed that the show always had a theme of tragedy, wherein viewers already know that a character has a "bad fate" yet they continue to hope that nothing wrong would happen.The EP also confirmed that a much different version of Norman will be seen in season 5, with his personality much closer to the one in the film. On the other hand, the events in the plot will still keep true to the series and not just a copy of the movie.

"They will cross paths with some of the events in the movie and lead to an ultimate resolution. What that resolution is and how that plays out is something that will be not disconnected to the movie Psycho but will be very much our own story in the same way the entire series has been," he added.

As for new faces to be in season 5, the most iconic "Pyscho" victim Marion Crane will join the show. "We do hope to see Marion Crane next season," said Cuse. "That will be a big moment." The role was originally portrayed by Janet Leigh in the thriller classic, and the execs have yet to announce who will play the role in the series.

A&E's "Bates Motel" returns to the small screen for its fifth and final season next year.
