Black Fog
The beast tamers present in the room were more invested in the current fight than the previous one. While they were impressed that Satoshi was able to defeat White Mist, they were even more amazed that Satoshi could hold out his Beast Integration for another round. While they assumed that Satoshi would be able to hold out until the end, they have no idea how strong Ash actually is. That's why they looked forward to the match.
"So... Ash is Jean Grey's son, right? That means he trained under a proficient beast tamer. There's no way he's subpar."
"Let's not forget, Satoshi challenged Ash as soon as his fight against White Mist ended. That means... he's confident that he'll win."
"Satoshi's already at a great disadvantage, but I still think he'd be able to win."
