"Harry, do you know why Dumbledore was great?"
"Didn't the Chocolate Frog card explain it in detail?
Alchemy, and discovering the twelve uses of Dragon Blood. Hmm, and for the peace of the wizarding world, parting ways with his lover." Faced with Ginny's sudden question, Harry replied.
"No, at least that wasn't why I thought he was great.
You'd often heard me mention Aunt Muriel before.
Actually, she was Mum's aunt.
We should call her Great-Aunt Muriel.
Maybe because I was a shy little girl when I was young.
She told me many secrets that only she knew." (Ron wore an aggrieved expression: "What? Why didn't she tell me?")
That included the Dumbledore family.
From now on, I'll refer to Dumbledore as our headmaster.
That'll make things easier to distinguish.
According to Muriel, nearly all the Dumbledores were strange.
The headmaster's father, Percival, liked using magic to toy with little boys.
Then he was sent to Azkaban.
Because of that, the Dumbledores moved from Godric's Hollow to Godric's Hollow.
The headmaster's brother transferred his interests to goats, and even his Patronus took the form of a goat.
When he was in school, he spent all day causing trouble and challenging people to duels everywhere.
The headmaster's aunt liked to play with Horklumps.
As a result, she fell out with her fiancé.
Yet the headmaster himself remained unstained by the mud.
Aside from his unusual sexual orientation, there was nothing anyone could attack him for.
Wasn't that great?"
"You remembered it wrong.
Or your great-aunt remembered it wrong.
Dumbledore's father used magic to punish those boys.
Because they bullied Dumbledore's sister.
And the one who liked playing with Horklumps wasn't Dumbledore's aunt.
More precisely, it was Dumbledore's aunt's fiancé.
She only broke off the engagement after discovering he behaved like that."
