The Black Dahlia in 'American Horror Story' is depicted as a powerful and menacing symbol. It is presented in a way that ties into the overall aesthetic of horror in the show. There could be scenes where the story seems to be haunted by the memory of the Black Dahlia. Maybe a house where strange things happen has some sort of connection to the case. The show might use lighting, music, and set design to enhance the feeling of dread associated with the Black Dahlia. For example, a dimly lit room with a picture of the Black Dahlia on the wall, and every time a character enters the room, there's an ominous feeling, as if the spirit of the Black Dahlia is present.
