Well Kaiba doesn't have evil in his soul anymore, but he doesn't respect Jonouchi one bit as a duelist. Think of it this way, a nobody with crappy cards stands up to you and tells you he is hot shit only to get easily defeated. No wonder Kaiba thinks he is just a pushover. Even more so in the eyes of someone like Kaiba, who values results more than the means! Anzu still stepped up to defend Joey.
And oh boy, we get a first glimpse of Bandit Keith told to us by Kaiba! This guy is one the best secondary characters in this arc imo (aside from Mai ofc). And we actually get a proper introduction about his character here, we never really delved much into him in the anime, which was a shame. Also the way Pegasas humiliated him and turned their face off into a card game commercial was brutal. No wonder Keith wants to get back at him!
also lmao
