Klaus glared at Jack as he let go of the tiny particles of the badge in his hands, in his eyes, Jack shouldn't have been ranked as a Mayor, he believed Jack got helped on the battlefield and a lot of people must've given him their credits given he was from a military background.
Although Jack was in stage two of the warrior realm, he didn't see Jack as a realm fighter, Jack only accumulated the energy, and nothing more, he wasn't able to utilize it properly.
This was also proof that Jack was completely useless, his family connection and resources were what brought him to where he was today.
"I am done with you"
Klaus's words were short and simple but the tone made it frightening.
Jack couldn't believe Klaus went on to destroy his badge, he couldn't believe that Klaus wasn't afraid of the Sawyer family.
