Ash and friends finally arrive in Petalburg City. Ash heads to the Pokémon Center (PC) to take care of his team while everyone else visits May and Max’s house. At the PC, Ash sees Norman talking to Nurse Joy.
At the house, Norman’s wife Caroline makes everyone lunch, and she seems very upset. The kids check out the greenhouse where Norman keeps his Pokémon, and his assistant Kenny explains that Norman has been going to the PC everyday to see Nurse Joy. The kids rush to the PC to yell at their father, just as Ash arrives at the house. Caroline shows up at the PC with her luggage and tells Norman she’s leaving.
Back at the greenhouse, Ash checks out Norman’s Pokémon and gets into a battle with Team Rocket. Everyone returns to the house in the middle of the battle, and something in the greenhouse is damaged that makes Norman very upset. He has his Slaking use Focus Punch on Team Rocket to send them blasting off.
It turns out that Nurse Joy was actually helping Norman prepare a fireworks display for his wedding anniversary, but it was ruined during the battle. Nurse Joys repairs the display, and that night they all watch the fireworks together.
