There's a girl near the Hogwarts lake.
She's under a tree and she's crying for the loss of someone closed to her.
Her husband died the night before.
The Aurors find his body in the Forbidden Forest.
His death was a terrible deed for the Weasleys.
Bill was his name. He was the big brother of Ron Weasley, the best friend of the Hero: Harry Potter.
The girl seemed crying, but she was only playing a part.
In her right hand there was a bloody knife.
Now she smiled.
"Well, well, who I see now? The beloved widow Weasley?"says a tall blond man.
"It's a such pleasure to see you again Lucius, I want to give you back this. I've done my job. Now my debt is paid", she said looking angry at him.
"You know, darling, it's a such pity to loose a wonderful slave...ops! I mean killer like you!" SLAP!
Fleur Delacour slapped him, she was so angry with him, but especially with her!
She knew the relationship between the Dark Lord and her was indissoluble.
Her debt remained.
Why?
Because HE gave her something incredible: Gabrielle's protection from the Death Eaters.
