Meanwhile, Team Rocket is about at the end of their rope with Malva's demanding schedule.

This leaves her wide open to an from Slurpuff, after which Tierno decides to recall the helpless Raichu and replace him with. Sawyer tries to open again with Attract, but Blastoise shrugs it off.

Ash worries that Sceptile is still the more powerful Pokémon, but when Tierno orders a, Clemont realizes that Blastoise's parting Rain Dance will ensure that Raichu's attacks don't miss. Before Raichu can release his Thunder, however, Sawyer reveals his secret weapon and uses his Key Stone to Mega Evolve Sceptile.

Errors

 * The with the, who was seen battling Astrid in the beginning of the episode, is the same Trainer  had to face in the first round. Since Tierno had made it to the quarter-finals and thus beaten this Trainer, it should have been impossible for Astrid to face her in the league.
 * When Astrid tells her Absol to use, it is shown as a regular Absol, but seconds later, when attacks it, it is shown as a Mega Absol. This is likely due to the fact that the animation in the shot where Astrid tells her Absol to attack was taken directly from Mega Evolution Special I, where Absol was in its regular form while using the move.
 * When Tierno sends out Raichu, its nose is smaller than normal.
 * When 's fails to work on,  suggests that it is because both Blastoise and Slurpuff are male. However, Tierno's , who had just been affected by Attract, has a pointed tail that male Raichu have.
 * When Sceptile used Leaf Storm to counter, Sceptile's Sceptilite, as well as the ends of the scarf, change position from near Sceptile's left shoulder to its right. Every other time they were seen they were shown near Sceptile's left shoulder.
 * Shortly after Tierno sends out Raichu for the second time, the back of Raichu's right ear is completely yellow instead of brown.
 * When Ash takes out his Pokédex it is shown to already be open, however when it is pointed at Sawyer's Aegislash, it is shown to open up again.
 * In the dub, after Clemont finishes talking about Blastoise eliminating Slurpuff's Attract, Clemont's mouth is still moving, but no sound comes out.
 * Shortly after Sceptile Mega Evolves, the scoreboard shows Blastoise instead of Raichu. Although when it shows Raichu after the battle ends, a different image of Raichu is shown.
 * Near the end in the dub, when Ash is talking to his Pokémon, his words do not match up with his mouth.
