This episode features the first Double Battle in the Pokémon canon, if some of the battles with Jessie and James are excluded from earlier in the anime. However, it should be noted that this battle ends when either one of the Trainer's Pokémon faints as opposed to the Double Battles introduced later in the games, in which both opposing Pokémon would need to be knocked out to earn the win.
Ash defeats Luana and earns the Jade Star Badge, his fourth and final Orange League Badge, allowing him to challenge the Orange Crew Supreme Gym Leader.
This is the second episode in which Ash is mistaken for another woman's son, the first being Sleeper and Pokémon Hypnotism!? (1997).
This is the first episode to have a referee in a Gym battle. Almost every Gym battle has a referee from this point on.
After Luana reveals her status as Gym Leader in the English dub, Jessie comments "I don't care if you're in the Orange Crew or the Grapefruit League." This is possibly a stealth reference to Major League Baseball's Spring Training league in Florida.
