Kai grew serious. "Tally, Frenzy Plant!" they commanded, thrusting an arm forward confidently.
Almost instantly, the ground began to rumble and every single Pokemon on the field except Tally himself was trapped in thorny vines. Tally gave all of the Pokemon long, wise stares of examination, evaluating each Pokemon for their battling style and current emotions.
Kai shook their head, sighing. "I hate to side with Eliza on this one, but she may be right, Zack. Not about you not having what it takes to join the Kalos League--no one does, at first. But you've gotta understand that Champions have a certain pride to them that allows them to play fair. This is something my sisters and I learned the hard way. If you were to ever see my younger sister--besides Sylvia--you'll know that despite the two having it in for one another quite often, they don't go out of their way to cheat to win. That would be disrespecting your opponent, your partner Pokemon, and yourself. Keep that in mind."
They glanced at Eliza, icy blue eyes piercing into her own. "Putting someone else below you and proclaiming yourself to be a queen compared to others will get you nowhere. All you gain from that is arrogance and false security. The same holds true for the opposite end of the spectrum." This time, they glanced at Sylvia, who flinched. "If you put yourself down below other people, you may never think you're worth it and thus not try to achieve your goals. You've known this for a while, haven't you, Sylv?"
Sylvia squirmed and avoided eye contact, refusing to say a thing on that matter. "Kai, you just paused the whole battle to give life advice? Come on..."
Kai sighed. "Tally, release them."
The Frenzy Plant vines gently let the Pokemon down and retracted into the ground. Kai extended their arm and held out Tally's Poke Ball.
"Return."
When Tally was out of sight, Kai turned around. "It was nice meeting you all. But I still think you all have a lot to learn," they said. Without another word, they walked off.
