You know, I've never really been a fan of Misty's sisters. They have more air in their combined heads than the Goodyear blimp, and they're more than a little mean to Misty. Yes, I know they're her sisters, but I think they're a bit rude. I may not be a Misty fan, but really, she's a good trainer.
It was interesting seeing Ash get to battle Misty, though. It's funny how they didn't resolve their battle until season three's "The Totodile Duel". Not only that, it's strange how Misty beat him in "Dueling Heroes", but made no mention of being even now or anything.
Of course, a big highlight is James's classic line of saying times like these make him want to go straight.

And we have Brock's first hit on a woman in the series, Officer Jenny. It's strange how toned-down he is in this episode, considering the slobbering job he does in most later episodes.
Overall, not a favorite episode of mine, but at least it had a few interesting moments.
