Legacies appeared to have killed off a major character when the Salvatore School headmaster had a brain hemorrhage, but does Alaric in Legacies season 4 die? The second spinoff series of The Vampire Diaries, Legacies had somewhat of a tumultuous few seasons as it struggled to get out from the shadow of TVD and the previous spinoff The Originals to forge its own identity. Legacies takes care to ensure its teenage characters are actually treated like teenage characters in their adventures, with Alaric often being the only adult in an episode. That's why the decision to kill him off partway into season 4 seemed so shocking.
