Hagrid sat beside his large table in his exceptionally large house, and his large heart was filled to the brim with concern for his missing friends and dead heroes. Dumbledore's death had struck him particularly hard, and it did not help that Hogwarts had changed significantly in his absence. It had been a difficult adjustment for Hagrid to bear, but he had pulled through well. He was having his tea on this Christmas eve with Fang lying next to his feet.
It had been odd not to set up the twelve Christmas trees this year, and it had not really felt like Christmas was approaching without shopping for gifts. His eyes teared up at the thought of Harry, Ron, and Hermione wandering on their own, and they only increased their volume when he remembered the white tomb sitting next to the lake. At these thoughts, his heart turned hard when his mind wandered to the murderer, the man who sat in Dumbledore's chair in the Great Hall.
Hagrid's hand stretched down to stretch Fang's head and behind his ears. He rose from his table and ambled over to the stove where the tea kettle was whistling. He poured himself a cup of tea and set it down on the table. Hagrid's eyes to the window and wondered how Grawp was feeling and what he was doing at this moment. After all, it was Christmas Eve, and he probably should go visit him and show him the gift he had prepared for his half-brother. He had a duty to look after his brother and his friends.
He took a sip of the tea, and slowly the wheels in his head started turning. He had a duty to his friends and those who had always been kind to him. Hagrid began to develop an idea, and it was the only way he knew of to show his support for the Boy Who Lived.
