Cerulean City is where all the action is: Misty's sister Daisy is back, Butch and Cassidy are coming to steal a Delcatty, and both Tracey and Casey, the baseball-loving Trainer from Johto, are visiting the Cerulean Gym. They're there when a Pelipper delivers a letter to Misty, asking her to meet someone named Georgio by the lighthouse. While Tracey is stuck with cleaning-pool duty, Misty and Casey go to meet the mysterious Georgio. He turns out to be a young Trainer who wants to ask Misty on a date! He even has two great tickets to tonight's Electabuzz vs. Starmies game, the one Casey wants to see.
Misty says no, but Georgio offers to battle her--if he wins, Misty will go to the ballgame with him, and if not, she'll never have to see him again. Misty agrees, but when Georgio sends out his Delcatty, Butch and Cassidy grab it! They were hiding at the top of the lighthouse and now they make their escape on hand-gliders. Georgio orders his Pelipper to stop them and Butch and Cassidy crash a short distance away. Misty and the others come running, but Butch and Cassidy send out their Mightyena and Sableye. Misty and Casey battle them with Misty's Corsola and Casey's Meganium; Meganium's SolarBeam blasts the Team Rocket villains into the sky and Delcatty is safe.
Now Misty and Georgio's battle can begin again. Delcatty may look prim, but its Double Team and Ice Beam moves are enough to knock Corsola out. However, Corsola uses Recover to come back, then knocks Delcatty out! Georgio has lost, but Casey begs for one of his tickets. He agrees to give her a ticket if she defeats him in a battle, so it's his Delcatty against her Elekid. Alas, Delcatty's Iron Tail is a one-hit KO for Elekid, but Georgio gives her his second ticket anyway. That evening, Casey and Georgio head for the stadium and Misty reflects on yet another day in the life of a Gym Leader!
- This is the last episode where Misty is seen in her original outfit.
- The ending is different in original and dub versions. In the dub, Misty says that she has "found her calling". In the original, she thinks about going to Hoenn and meeting Ash there.
