Six, Natalie was playing or acting, as if she does not know that the car, the suit is being used, Leonard. Natalie played a neat act of getting beaten by Dodd, while actually she got beaten by making Leonard willing by making him angry telling him a coward and his wife a whore. That was very interesting part of the film.
At the end of the film, or the begging of the consequences, when Teddy tells him that he has already killed the real John Edward Gammell. He realizes the truth that he killed Jimmy for no reason and yet, going outside and yet, going outside of the isolated house, where he killed Jimmy, wore his dress, he throws away the keys of Teddy's car and thinks that car behind Teddy's car and thinks that, he is going to forget this truth and make all the truths of Teddy, a lie since forgets every new memory, and he believes his note and handwriting, so he decided to search for the killer again who raped and killed again, who raped and killed his wife. For that to accomplish, he can not know the truth or he must believe the truth as lies, so he decided to write as lies so he decided to write a caption on Teddy's photo "Don't believe his lies"
