Hunter doesn't know yet that he is a grimwalker, and Belos doesn't know that the previous Golden Guard had survived his attack, growing into the present day. Hunter is very serious about his job, but at the end of the day he is still sixteen and he may talk like it sometimes, his young age annoying many in the Emperor's Coven. He believes that without Belos he would be nothing, so he gladly serves him despite the Emperor's outbursts and cruel punishments, majority of his scars coming from him.
