[He only has a moment to feel scared before the pain at least. He's definitely going to jerk away, or try, but if he's stuck obeying he's just going to scream. It's way too much, he's already running on trauma. He's shutting down, emotions kind of flatlined under the pain, tears running down his cheeks as his skin sears.

He's yelling, begging Simon to stop, and then, as his skin takes the brand, he's cursing him too, but he's hardly aware of it. He isn't aware how his eyes have gone from fuschia to red or his hair from black to white or how his screaming had turned into furious, guttural howling growls.]
