Violet's master promised him to not wish for his last one so that she would be forever at his side, (since Dylan had developed his relationship with hers as a "friend") seeing him with another girl that was killing her, Violet never knew that pain could also kill an immortal Genie and so it was already killing her. Her skin began to pale, lips turning peach and hair turning black as a sign for death. However, Dylan asked Violet anything before she dies. He then granted his Genie's wish: A deep kiss from a mortal. As Violet had her last farewell, Dylan was the one who vanished, disappeared---died, instead of her. And there, Violet travels to find her master's soul that could risk her life, but her master already did and it was time for hers.
