The third round of the Official Beast Tournament was approaching its climax as the second to the last match was about to start. This was the best time for the commentator to hype the audience up, and he did a splendid job at it, screaming at the audience while putting out information about the beast tamers duking it out in the third round.
Quite frankly though, he was just stalling for time since Luke Skyrunner was nowhere to be found. He couldn't believe that he had just up and left without notifying him. And now, he was left alone to commentate on the match. Adding to that, if something were to happen during the match, he has to take care of it. Hence he tried so hard to buy some time until Luke Skyrunner comes back.
One of the guards who were patrolling the American Stadium knocked on the door of the box where the commentators are located. He didn't wait for someone to signal him inside but opened the door without hesitation.
