Intro
Emma: Guest... you actually became a demon king? No. No, I refuse to believe it. This has to be some kind of sick joke.
Brooke: Guest, please just tell me it's not true. Because if it is... I don't think I can keep going anymore.
Hanna: Guest, I'm begging you—say it's all a lie. Can't you come back to us? Can't things go back to how they used to be? We need you. We love you. Just like we always have.
