Candace's character has been a mystery ever since we're first introduced to her. We know she is Joe's ex-girlfriend and allegedly moves to Italy after they break up, but it's sketchy. At first, it seems like she might be dead, though we never see her get killed. Then, in the final moments of the season finale, Candace shows up at Joe's bookstore, saying they have some "unfinished business to talk about." Could it be about how Joe killed her other boyfriend, Elijah?
