My Sibling Will Live Through Me: Difference between revisions

* One episode of ''[[Star Trek: Deep Space Nine]]'' featured a pair of twin aliens. When one was killed, the other explained that twins in his species are essentially one being (leaving him as only half a person). Referring to his deceased brother as the only thing that made life enjoyable he asserts that the only joy he will ever feel again will be from taking his revenge PERSONALLY on the killer. He explains that letting the local law or even the killer's home planet (where he is slated to be executed) deal with him is not good enough.

* Actually doubled up on in an episode of ''[[House (TV series)|House]]''. Count 1: The [[Patient of the Week]] is a teenage girl with a sick brother who seems driven to live the life he'd be living if he weren't sick, so that he can experience it vicariously through her. Count 2: Eventually, through some [[Applied Phlebotinum|Medical Phlebotinum]], it turns out the only way to save her is a {{spoiler|treatment that will shorten his life significantly. She first tries to kill herself when she realizes what her parents are arguing about, but then her brother tells her he wants to live on through her continuing to live.}}

** It's somewhat more gruesome than that. Not only does Buffy tell her sister to live for her - she herself also deliberately dies for Dawn, since spilling the blood of Dawn was explicitly the only thing that could stop the impending apocalypse - until Buffy realized that as the older sister, [[Take a Third Option|she would also quality]].

* ''[[Law and Order SVU]]'' inevitably had the creepy parents-replace-dead-child-with-her-sister version.
