On the island, Harry relished seeing Dumbledore brought so low by Tom's potion. He deserved it for every single thing he had done to Harry's soulmate. Not about to let this opportunity pass, the younger wizard penetrated his headmaster's defences. He learned about Grindelwald, Tom's father and Ariana. How Dumbeldore was already suspicious of the Lord Peverell yet was still unable to openly oppose him in the Wizengamot. How his spies and Order Members had investigated Tom but found nothing useful so far. He continued feeding the headmaster the brew until the locket was revealed. Since Harry offered no target, the inferni stayed in their cold graves. He guided the headmaster to the boat and paid the blood tribune to open the archway that sealed the cave. He smiled triumphantly when he stepped into the now cloudless night. This evening had been most educational.
