By levitation, I mean he levitated by a spell. The spell being a hex named Levitation Charms. That spell lets him float by simply holding things up to the ceiling (which is essentially what happens when he levitates) and then releasing them at high speed using Charms.”
Harry nodded in agreement in his mind. Yes. And there were more?
“He’s actually kind of slow in the water, which I was surprised. He must actually slow down in the water to use Charms and he’s able to do so by holding two objects up to the ceiling and releasing them at high velocity, making a low and slow speed motion.”

“What about when you get home?” Draco asked. “Where will Draco live now?”
“At the Dursleys’ house,” Harry answered. “They’ve been giving me
