The Vampire Diaries‘ Lorenzo (Michael Malarkey)–also known as Enzo–never had it easy. Initially an antagonist who becomes more of a hero as the show progresses, Enzo was an orphan who grew up on the streets of England. He was turned into a vampire by Lily Salvatore, seemingly abandoned by his sire and experimented on for over a decade by the Augustine Society. He falls in love with the woman studying him, Maggie James, but Maggie is murdered eventually murdered by Damon Salvatore (Ian Somerhalder). He ultimately befriends Damon, but the vampire leaves him to die when he starts a fire and escapes the Augustines.

Enzo’s died more than once, and as soon as things are looking up for him and Bonnie (Kat Graham), he’s killed for good by Stefan (Paul Wesley) when he tries to kill the comatose Elena. Given that death is pretty common in the series, it’s no surprise Enzo didn’t make it to the series’ finale. But why did Stefan kill Enzo in the first place?
