Ok, after watching this episode for the first time ever the other day (thanks to Youtube), there was something I needed to ask:
Alex Davis (the trainer Gary battles at the beginning of the episode) sounds like he was played by a real child (rather than a voice actor). Now what I was wondering is, even though Kayzie Rogers got the credit, does anyone know if the voice was performed by a child (competition winner, Make-A-Wish etc.). Only the other things I noticed was it's very rare that any trainer is given a full name, let alone one who only appears a few minutes. Also, Alex Davis' physical appearance didn't match the voice. If anyone knows the answer to this that would be great.
