Aah, I remember that. Really showing my age. Good ol' AAML.
Wow! Such dedication is admirable.I was wondering if character interactions varied between different writers. While going through summaries of episodes written by Hideki Sonoda, I found a potential hint in Beauty & the Beach: "As Pikachu swims around in a little inner tube, Misty shows up holding a Master Ball beach ball and says that she thought they were going to meet her at the snack bar. They stare at her for a moment, and Ash notes how odd it is to see Misty look like a girl. She gets mad, and throws the ball at his head, knocking him into the water."
