Chris repeatedly tried to test Jordan's patience, so Jordan had long wanted to beat him up into a pulp.
Chris previously insulted Jordan and called him poor, but Jordan couldn't retort because he was indeed really penniless now. If he were to get physical, it would be akin to admitting that he was an incompetent loser and that he was jealous of Chris, who was wealthy.
However, it was a personality issue for Chris to insult Jordan by accusing him of having an affair with Lisa.
However, Jordan's punch did not land on Chris.
Chris was undoubtedly a martial arts practitioner. He hurriedly raised his arm to resist and got into an attacking stance. He yelled, "Do you want to fight? Bring it on! Since the last time I fought you, I've been wanting to fight you every single day!"
Chris was defeated by Jordan the last time, and after that, he had been training hard every day in a bid to regain his pride.
