To Hagrid, the Ministry of Magic's Investigator was terrifying, because the Investigator had the authority to send him back to Azkaban.
But the Board of Governors' Investigator was troublesome, because Amosta could represent the Board of Governors and expel him from Hogwarts. Though Hagrid knew Headmaster Dumbledore would certainly speak up for him, it would still be an enormous hassle.
Amosta and Hagrid trudged with difficulty through the depths of the Forbidden Forest. Though it was daytime, the dense trees blocked most of the light from the sky, leaving the forest dark and gloomy. Amosta had no choice but to draw his wand and light it for illumination.
The surroundings were utterly silent. Even when they listened closely, they could hear nothing apart from snapping branches and the patter of rain against leaves.
