This is Billy Sighten, a German teenager, age 16. He went blind from a fire caused by faulty wiring in his home, back when he was 5. He got bullied over his school years, but he did make friends. He also, overtime, managed to calculate distance, shape, size weight, texture, and look of objects just by feel, sound, smell, and taste, alone. one day, in middle school, while being bullied, he snapped, and he grabbed one of the bully's heads, and began digging his thumbs into the bully's eyes. He caused the bully to go blind, and his family moved to America, as soon as the school day ended. There, he was found by a man named Kevin Wendell Crumb, who would train Bill how to truly be a psycho. After he found out Crumb killed Mr. Glass, and found out Mr. Glass's bones were made out of PURE GLASS, he didn't want to work with Crumb anymore, he wanted to help Mr. Glass recover, and finally kill Crumb, once, and for all.
