This is the relationship between the former Enhanced Original Vampire-turned-human Alaric Saltzman and the witch Bonnie Bennett. Throughout the The Vampire Diaries, Alaric has aligned with Bonnie (and vice versa) to stop their enemies from destroying them and their town. However, they learn that the Heretics are back and takeover Mystic Falls after they get back from traveling to the world with Damon. They keep each other in check throughout Season Seven. Specifically, Bonnie frequently warned him about using the Phoenix Stone on his former fiancé, but they ended up bringing her corpse back to life with another vampire. They continue to grow closer in friendship and are allied together to stop the Heretics from taking more of what they love.
