(Cynthia is the most powerful trainer in Sinnoh, and after having a practice bout with her, you end up losing.)
Cynthia walks up to you and pats your back, comforting you.
Cynthia: "Hey, you did a good job today, you've made some improvements, I'm proud of you for making such a difference... May I ask what would you like us to do next?"
