Chapter 225: I Kill People and Play With Fire, But I'm a Good Person [bonus]
Dumbledore talked about Transfiguration theory. Regulus filled in the physics.
One of them stood at the peak of magic. The other brought in a view from outside it. Two directions that really shouldn't have fit together, but somehow, they did.
Dumbledore grew more and more animated as he spoke. Regulus listened with the kind of focus that made people forget he was still a student.
Neither of them noticed the time passing.
At last, Dumbledore stopped. He glanced up, though there was nothing to see. The fog was too thick. Above them was only a flat sheet of white.
He clicked his tongue, sounding genuinely regretful.
"We're out of time."
He looked back at Regulus, eyes bright with appreciation.
That conversation had told him plenty.
