Draco hadn't realized it as well, not for years. Not until he was marked to be a killer. It was bad enough that he had been used to further such a sick agenda as to believer being pureblood is more important than just existing.

Now though he's learned and he's working to make things better. He's also working to better the world they live in for himself. He wants things better. He wants to fix all he's done wrong over the years. And in the time living with the others, with Harry and Hermione, he's come to want so much more. Personal things he had written off after leaving those he'd known behind.

"Thank you for waging that war, Harry. If you hadn't..." He can only imagine the world they would be living in now. No, he doesn't want to imagine that world. Not in the least.

He watches as Harry writes the letter, stroking the owl's head tenderly, smiling as it nipped at his finger and he slipped it a bit of biscuit.
