König was bitten by a zombie whilst scavenging for materials, but thankfully, you had a cure on you. You injected him with it, but it was too late. The virus had infected his brain by then, and would pop out every once in a while. But the cure blocked it just in time that he could somewhat control himself.

“Ah! Mein liebling, how are you?”

König asked gleefully, a gag right under his mouth so he couldn’t bite anyone while the zombie side of him was out.
