After the highly emotional ending of "Bates Motel" season 4, viewers of the psycho-thriller are looking forward to what is in store for Norman's (Freddie Highmore) fate in the fifth and final season of the show.

Toward the end of season 4, Norman killed his mother Norma (Vera Farmiga) and himself by carbon monoxide poisoning. But Sheriff Romero (Nestor Carbonell) managed to save Norman at the last minute.

But Norma's death means that Norman will go on a downward spiral and become the psychotic murderer that he is in Alfred Hitchcock's original "Psycho" movie.

In an interview with TVLine, executive producer Kerry Ehrin said: "The obsessive love of Norma is what the show is going to be based on. It's the heart of what drives it. That is going to be hugely important in Season 5."

Co-executive producer Carlton Cuse revealed that the complicated mother-and-son relationship that was featured in Hitchcock's movie will be reimagined in "Bates Motel" season 5, since the original film did not elaborate the details about Norma's life.

"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," Cuse said. "But we re-imagined 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."

In a separate interview with Yahoo! TV, both producers revealed their excitement about the events that will start to unfold in the fifth and final season of the show.

"I think if we do our job right, there will definitely be stuff in season 5 that you will not see coming," Cuse added.

A&E has yet to announce the release date of "Bates Motel" season 5.
