"Not in the conventional sense, no," Harry agreed. "But Riddle was doomed the moment he entered that house. It was their love versus his hate at that point. But on their ground, on their terms. They set ritual and runic traps for him everywhere and my father led him into each one. He was ridiculously brave, and so obscenely clever. They all drew aspects of Riddle's power, duplicated it, then channelled it into me. The final one - the one that killed my Dad - was a Parseltongue spell. He didn't even defend himself. He used blood magic on his death to funnel that ability into me."
