How does Unbreakable end?

In the final moments of the film, David attends a comic convention at Elijah's Limited Edition store. There he uses his hyperadvanced instinct and, to his horror, discovers that Price has caused several terrible disasters, including the train accident that opens the movie, in order to find someone who would miraculously survive as David did. The evidence is shown in blueprints of trains, buildings, and other areas, which showed their weakness, bomb-making kits, and other items. Price insists to Dunn that he performed these deeds, and they are justified by finding him. He then explains that he has come to realize his purpose in life by comparing his relationship with Dunn to that of an often repeated motif in superhero stories: that the hero and the villain are opposites, and often even friends at first. Before David turns his back on him, Elijah pleads with him to understand the feelings of loneliness and the supposed lack of purpose in life. Captions run, saying that after leaving, David informed the police about Elijah (whose office is littered with newspaper clippings and evidence right in the open that he was responsible for the disasters). Elijah finishes his sentence saying, "I should have known way back when (that he was a supervillan), you know why David? Because of the kids...they called me Mr. Glass." The film ends with the caption that reads he was arrested and sent to an institute for the criminally insane.
