In my headcannon, Twylight and Sunny’s mama be there. And Opaline reveals Twylight’s sins; the Lesson Zero incident, hurting Spike over the owl incident, the Marer Do Well and Walking Dead incidents, prejurdicing Dyscord and Zecora as well as Capper, her doubt in Pinkie which nearly got others eaten by paraspites and a hydra, scaring Flurry Heart, causing the avalanche, the Storm King affair including how her gambit to rob Novo and how she upset Pinkie, her betraying the CMC for Cozy Glow, her neglecting to visit her human pals more, and her cheating on the game with Pinkie…….. all of which helped her. ANd Sunny accuses her of lying to which Twylight admits it’s truth and memories be shown on a gem. And Opaline compares Twylight to herself and recveals Sunset fell trying to rescue her. And try to tempt Sunny to punish Twylight. But Sunny chooses mercy and forgiveness, and hugs Twylight.
