A late–night truth session at Prince Manor peels back Harry’s third–year secrets. He relives Dementor memories of his parents’ last moments, admits how the Marauder’s Map and Time–Turner freed Sirius, and hears Snape’s clear reasons to master Occlumency before learning the rest about the prophecy. A hard realization about Sirius’s lies follows, and the fragile, steady trust between guardian and ward tightens another notch. This is close, character-driven Snape-and-Harry mentorship with canon-deep lore made for headphones.
