"What do you want from me, Astoria?"
"Anything?"
"Everything." Lucius' voice is a soft, fierce growl.
"Commitment."
He pulls back, lips white as though he has just been punched in the stomach. Shock drains him.
"You want me to leave Narcissa."
"I want a man who will stand by me, only me, for the rest of our lives."
"Isn't there something else you want? Anything else?"
People can't give what they don't have. Astoria knows this, but she cannot be satisfied. That is why she will marry Draco. Because even with all his shortcomings, Draco can devote himself to her, only her, for the rest of their lives.
