Dumbledore took the two boys, who's parents had then been awakened from their duels with Voldemort, and switched their cores, Harry lost his magic, and Charlus regained his. The switch had been covered up, Harry being said to be a squib, but what if one day, Snape accidently let it slip, not knowing that Harry was eavesdropping?
