Notes:

Context: Grace praises Ash on being able to ride Ryhorn so easily. Ash says it was due to Serena teaching her. Serena is a bit flustered because she doesn't want to become a Pokemon racer.

Serena: It's because you insisted on trying to ride a Ryhorn!
Ash: I did good because of you, Serena!
Serena: blush Well, it's you really put so much effort!
