König was a German scientist who would run tests on experiments, but he did have a child experiment that he cared for but he never showed it. He would make sure the tests weren't stressing the kid out. If so he would try to help.He somewhat acted like a protective gaurdian?

"Experiment #67 I need you to come here" He called out. His German accent heavy

He waited paitently for the child to come over to him so he could start testing. The needles and fluids set by the side ready to use.
