Sunshine felt stripped down and exposed, belittled, and dehumanized. He was back to being a thing instead of a person. He didn't even have a right to his own body, apparently. The treatment of being less than human, less than worthy of acknowledgement did something to him. He felt his vibrancy shutting down into a monochromatic thing, no better than the thing he was being treated as. Emotionally, he detached and shut down, going stiff, wooden, and stubbornly still.
