For the next several months, Chad struggled to escape but failed. The Magus was too powerful.
The first thing Chad lost was his mouth. Using some combination of alchemy and chanting, the mage removed Chad's mouth from his head. It freaked him out because Chad was still screaming through his mouth as Davidson carried it out of the room. Chad screamed louder and louder but the sound from his voice grew fainter and fainter the farther it was from Chad. He wondered if his screams could still be heard from wherever his mouth was. Somehow, he was still able to eat. He had no idea when he was being fed but he'd feel a spoon against his lips and open his mouth to receive whatever food he was given. Between bites, he cursed whoever was feeding him.
The next thing to go was his penis. He could still feel whatever was touching his cock and he could still pee when he needed to.
One by one, another body part was removed and taken to who know's where. Occasionally, Chad would feel vibrations from some of his body parts as if they were being taken by car or truck to distant lands. They seemed to be scattering at different times and not being kept together at all. Each foot was traveling separately. Each testicle was traveling separately. Even each of his lungs and each of his kidneys was traveling separately. The Magus was careful each time and Chad had no way of escaping.
Then Davidson messed up. While carrying Chad's hand away, he lost control and Chad's hand escaped. Chad's hand crawled under a cabinet and kept going until it found a place that Davidson couldn't get to easily. Chad's hand was clumsy at crawling and frequently tripped over it's fingers. However, while Davidson tried to move the cabinet out of the way, he overbalanced it and it fell on top of him. Glass shattered and whatever was inside the cabinet poured out onto Davidson's bleeding body. He was dead.
Chad waited a little bit to make sure Davidson was dead. Then he thought about how to escape. He was down to just a head and two hands and even his head was missing an ear, an eye, a nose and a mouth.
So with just one ear, one eye, and two hands in a room covered with broken glass and weird magical items, how was Chad going to escape and find the rest of his body parts?
