At the sound of his cry, Jayne felt a strange, pleasant feeling in her mind. She couldn't actually be enjoying hurting someone, could she? Though she admitted it was sort of cathartic, that didn't quite explain-
"Don't worry, my dear. I'm just making sure you have fun. Keep going."
She nodded to herself, already angry and wanting more of that pleasant feeling.
"So, you have a voice after all. I can't wait to hear more of it." And with that, she pointed her wand at the boy's right hand and cast two spells - one aguamenti to cover it with water, quickly followed by a freezing spell to turn the water to ice before it could hit the ground, thus encasing the hand in ice.
