"Come here, son."
The once round faced boy approached. His eyes were glazed over and his skin, once pink and healthy, hung on his bones like grey, rumpled bed sheets. He drew himself to the dark-haired woman who put her long fingers into his hair. She caressed him indulgently, and he leaned into her caress, closing his eyes as she smoothed the hair behind his ear. Like the good dog he was.
"Mommy loves you very much, Neville-dearest. Do you love me, honey? Of course you do. Do you want to prove to mommy just how much you love her?"
The boy nodded enthusiastically. Of course he did. Mommy was all he had left. Mommy hadn't let the men in robes and white masks hurt him, even though his friends had all been taken away screaming. No, mommy had rushed out and saved him and taken her with him. At first he had been frightened and fought against Mommy, but she had been gentle with him. Understanding like any good mother. She beat him within an inch of his life when he was bad, but he had deserved it. When he was good and listened to Mommy she was kind. She gave him sweets and kisses and laughed with him. When she gave him bubble gum he saved the wrappers, putting them into his pockets until he crinkled when he moved they were so full. At night he would take them out and rub them lovingly between his fingers. He thanked his mommy for giving him the bubble gum and leaving him the wrappers. She was so kind to him,
He grew to adore her. She was the only one he ever saw.
"Come Neville-dearest. You do love me, don't you?"
He nodded. He loved mommy very much.
"Show me, Neville, show me you love mommy."
There, like a mewling infant, Neville Longbottom took the breast of Bellatrix Lestrange into his mouth and proved his love for her.
So, like I said. Whatever you want. It give me practice.
