Karl was minding his own business, sitting at his desk as he worked on a project for a new experiment. He was much too focused on the scritching of the pen on the paper to hear you come up behind him.

Karl had only gotten to replace your arm and a bit of your side as you were a newer experiment, yet here you were, holding a razor sharp piece of metal to his throat as he began to grin.
