"The accident already happened, is it really okay for you all to keep discussing it here?"
The person who stood up wasn't Scott Ward. If Scott Ward and Mallia Mamet were partners, it would make sense for him to stand up at this point, but Scott was also blaming Mallia for the accident and dragging the whole program down.
The one who spoke up was Matt Andrews. He's not usually the type to stand up for justice, but he's upset. If the show gets suspended, he doesn't know if he'll have another chance to interact with Aria Grant like this.
Listening to people endlessly discussing the accident while feeling annoyed, Matt's mood only grew worse. So, he directly confronted those people.
But those people didn't really take Matt's words to heart. After all, compared to the celebrities, Matt was just an ordinary person with no status or influence.
