Richard felt his head exploding when he heard Dean's words, he had already agreed to say please the first time because he was feeling down from what transpired with the Bruhm Family. His intention in fighting with Dean was to humiliate him and also vent some of his anger.
The fact that the duo took the first and second spots infuriated him as well, so he wanted to make up for losing out on the rewards.
Even after swallowing his pride to plead with Dean, Dean was still being unscruplous.
Dean had a grin on his face, clearly enjoying messing with Richard.
Richard looked at him coldly, "If you want to remain a coward, you can stay there, piece of trash!"
He couldn't hold it in any longer. He was about to explode from anger.
Anthony took a glance at Dean when he saw how Richard was taking it.
"Fine fine, I'm coming. Don't cry when I beat the crap out of you." Dean snorted coldly and stood up, casually walking to the arena.
