History
Kenneth is another member of the House of Kronenberg, however he comes from a different branch of the family to Sean, Eric and Viktor. He developed a reputation for getting results.

Arriving in Portland, he first interrogated Adalind Schade, learning that Nick was once again a Grimm, and that Juliette was now a Hexenbiest, he then discovered she was pregnant again, and enquired who the father was. Adalind lied that it was Viktor. Upon his apparent agent Sam Damerov arriving to give him the progress on the search for Kelly Burkhardt and Diana. Kenneth immediately realized that Sam was in fact secretly working for Sean, and violently beat him to the ground, then told Adalind that Viktor was incapable of having children so she better guess a better father.

He then forced Sam to call Renard so they would meet. Before having Sam brutally executed, arriving he confronted Sean. And unlike his predecessors didn't even bother trying to negotiate instead he simply attacked him. The fight broke out between them, although Sean was super humanly strong, Kenneth managed to hold his own. Half way through the fight however, Sean's condition began acting up, weakening him enough for Kenneth to beat him. He then mockingly told him, he worked his way or he would die.

Later Kenneth realized that Nick must have a way of communicating with Kelly, and began to formulate a plan. Returning Adalind revealed Juliette was after her, but Kenneth found this more amusing, and began planning how to use this to his advantage.

Discovering Juliette had been arrested, Kenneth decided this could be used to his advantage and planned to corrupt her, as she knew Nick and his mother much better than all of them, and thus might be the key to finding Diana. Adalind was originally sceptical, but then Kenneth enquired again about who the father of her child was, before smugly telling her he knew it was Nick. He then revealed that he planned to sacrifice Adalind to Juliette, and let Juliette know Adalind was carrying Nick's child.
