HOW DUMBLEDORE GOT UMBRIDGE BACK FROM THE CENTAURS
It was quite easy, actually.
Albus Dumbledore strode into the Forbidden Forest and found his way to the centaur's lair, where he found Bane, along with all the other centaurs, positively quivering in horror as Dolores Umbridge sat sobbing and screaming and tantrumming in the middle of the cave.
"TAKE HER," they begged Dumbledore, "TAKE HER!"
"That will cost you twenty five Galleons and ten Knuts, please," he said pleasantly, "as I am doing you a great favor by unburdening her of you."
The centaurs thrust the headmaster the money, plus a bit extra. "Get her out of here!"
Dolores looked up. "Get me out of here!" she shrieked. "No lace, no one to bother, no nothing!"
Dumbledore's eyes twinkled as he gently carted the Defense Against the Dark Arts teacher away.
That's how it happened :D
I don't own a penny.
