Despair
Being strangled in the neck by the blood rope, Henry couldn't even put up an ounce of resistance. The noose slowly tightened around his neck and with just sheer force, made his head explode within a second.
Two people came into his mind before he forever lost consciousness. One was his aged mother who was alone at home and was waiting for his return.
And the other was the blonde young lady, whom he was supposed to get engaged to next month. Ironically, he had met this lady at Ron's house on the day of the first snow last year.
The end of the blood rope drilled inside Henry's body through the opening in his neck and drained all the blood inside until he had become a shriveled corpse. All of this happened in a quick instant! Not even a second had passed.
Since Emma was right next to Henry, she was the first to react. When the latter's head exploded, the blood splattered all across her face.
