Lili Reinhart is a fantastic actress, and she has managed to portray two distinctly different iterations of Betty Cooper in a flawless manner.
I think that will always be a part of her character," Aguirre-Sacasa told The Hollywood Reporter. about Dark Betty.
"With the darkness, either Betty was denying it, or it was controlling her. There was a struggle to understand it. I think that will continue. Again, rather than do another season of Betty struggling with her darkness, she's dealing with it another way or turning away from it or controlling it. Lili is such a wonderful actress that you, of course, want to give dark, dramatic material to. But I was so happy to see her in the finale smiling in the hotel room and walk away from the darkness that I don't want to deny that part of her as well."
