This is a very insightful piece with many striking and beautiful turns of phrase. The theme of the Unforgivable curses is a powerful way of expressing Albus's sense that as he discovers himself, he is falling into evil. He feels pleasure, but can't understand it as pleasure, only as pain turned inside-out. He feels desire, but it seems to come from somewhere outside himself, something forced on him. And he feels the change in him, but he doesn't see the possibility for freedom in that change, only the death of what he thought he was and should have been. Reading this, you feel very deeply what an impossible situation life had cornered him into, and why he would have come to see his sexuality as something unwanted and terrible. Impressive work, MA!
