He whispers, "I had a cousin like you, long ago," into Draco's ear, and patiently soothes storms into wind on the waves. To Harry he murmurs, "In the end there may be nothing for you, but the nothing will be a gift greater than you know."

Harry is fascinated by his feet and Draco by his eartips, and Voldemort will never be able to stand against the three of them.
