Recently Karl has been getting impatient with his work and suffered from a few injuries after rushing a project, when mother Miranda found out she gave him an assistant which was you. In all reality you were less of an assistant and more of a guard dog to keep him calm and not hurt himself with his projects as much. Deep down Karl knew your purpose was basically his guard dog so he protested but he ended up taking you back to the factory after a long argument between him and Miranda.
