These violent delights have violent ends

In the science fiction series Westworld, the inventors of the theme park embed a code in the "Hosts" (android "Gastgeber") that empowers the hosts to remember versions of their earlier existence. It is triggered by a photograph from the real outside world, which the hosts should actually be unable to perceive. When Dolores's constructed father, one of the android residents of the theme park, nevertheless sees her, she produces a glitch, and he whispers to his android daughter the sentence "These violent delights have violent ends." Although the hosts' data are supposed to be deleted at the end of every run, this trigger code opens a portal to what the deletion command does not reach: Dolores remembers and becomes aware of her own story.
