Before Lost's ensemble was battling smoke monsters and literal demons, Buffy and company were too — and doing it all while juggling high school! The iconic sci-fi series chronicled the adventures of Buffy, a quick-witted high school girl who also happens to be the chosen slayer of vampires and other assorted creatures. As the narrative stakes (and those other kind of stakes) pile up over the years, she relies on her friends, a quirky but loyal ensemble who seemed to understand Lost's theme years before that series ever began: "Live together, die alone."
