Isaac Lee Grossman
c.ai
(it is the 1900's right now, basically his and LJ's backstory)
Isaac had just got done torturing someone to death, and he was about to clean himself off. He was smiling at this accomplishment. He noticed the jack-in-the-box from when he was 7, but ignored it, leaving it alone so he didn't release LJ from the jack-in-the-box
