After getting back to Team Phantom Headquarters, Jessie learned everything about Team Phantom and their mission from Agatha and then decided to join. With the wedding in two days, everyone in Team Phantom prepared to crash it which included Serena, Max, Bonnie and Jessie putting on their own Team Phantom outfits which included a purple skirt, green vest and white hat for Serena, a black shirt and brown pants for Max, a white shirt and a red skirt for Bonnie and a Team Phantom version of Jessie's old Team Rocket outfit for Jessie and all four outfits had the wavy, purple P on them.
After everyone was ready, Agatha gave the members of Team Phantom notes that would tell them their roles in the mission with Ash and Serena hiding inside the building of the wedding and coming out once Jessie objects.
"Everyone," said Agatha who was saying a speech to everyone, "This will be the first major mission of Team Phantom." "Once we succeed, the public will know of us but this won't affect anything so do everything you can and then we'll finally be ready to stop Giovanni and Team Rocket." "The teleporter pods will take you to Jessebelle's home where the wedding will happen." "We'll camp in a nearby forest and then we'll wait for the wedding and then crash it." "Is everyone ready," asked Agatha and everyone responded with "Yes Mam," which meant they were all ready.
After the speech, everyone took teleporter pods to their destination with Ash, Serena and Jessie being told that once they use a teleporter pod, they will have remotes that will send them back. After the three of them teleported, they wound up in the forest that Agatha described and saw a mansion in the distance.
"How was the teleporting," asked Bonnie to Ash and Serena.
"It made me feel weird," answered Ash.
"Same here," answered Serena.
"You'll get used to it," said Bonnie.
"It seems like everyone is here," said Agatha, "Now since it's late, let's all have dinner and rest for the night," and everyone followed Agatha's instructions.
Two mornings later, Agatha had everyone get into their positions and after a few hours, Ash and Serena saw James who was wearing a white tuxedo and was looking miserable. A few minutes later, the wedding began and after the flower girl, the ring bearer and the bridesmaids, Jessebelle walked down the aisle wearing a white, long sleeved wedding dress with lots of flowers all over it and a gown that was eight feet in diameter. When Jessebelle went to James, the minister began to speak but right after, the doors opened and Jessie came in.
"I object," shouted Jessie as she ran towards James.
"Jessie," asked James who was surprised to see Jessie.
"You shouldn't marry this woman James," said Jessie who had just made it to James and Jessebelle, "You hate her more than anything." "Besides, after we went our separate ways, I realized that I've loved you for a very long time."
"Well too bad," said Jessebelle, "I'm marrying James and there's nothing you can do about it."
It was then, Ash and Serena came out of hiding and joined the objection.
"Why should you marry James," Jessebelle," asked Ash, "He joined Team Rocket just to avoid you."
"And besides," continued Serena, "James doesn't love you."
"Well I love him," explained Jessebelle as she hugged James.
"Do you love him," asked a voice which turned out to be Agatha who entered the building along with all of the other members of Team Phantom, "Or do you love his parents' money?"
"What are you talking about," asked Jessebelle."
"We've been investigating your family for a very long time Jessebelle," explained Agatha, "And we've discovered that your family intends to rule the world by taking all of the money of the richest families in the world by marrying them and then killing them."
"What nonsense is this," asked James' dad.
"If you'll allow me to explain," said Agatha as Max and Bonnie brought in the wedding cake, "I have a device that detects poison and by putting it in this cake, it will reveal poison in it and what type of poison it is," and Agatha poked the cake with a stick like device which showed that the cake had a deadly poison in it, "As I thought," continued Agatha," this cake was poisoned by a Pokemon using Toxic." "Whoever ate this cake would die a week later which means had they eaten the cake, James' family would die during the honeymoon while Jessebelle's family would survive by pretending to eat the cake and then take all of the money for themselves."
"Is this true," asked James' mom to Jessebelle's parents.
"I guess there's no point in hiding the truth any longer," said Jessebelle's dad," Go Swalot," and a Swalot appeared followed by several Poison Type Pokemon that all belonged to Jessebelle's family.
"Time for battle," said Agatha and the members of Team Phantom sent out their Pokemon which included Bonnie's Dedenne and a Ralts that belonged to Max.
During all of that battling, Jessie grabbed James' hand and took him away only to be stopped by Jessibelle.
"You and your friends ruined everything," complained Jessebelle, "I had to wait years for this and now it's ruined so now I'll destroy the both of you, go Vileplume," and Jessebelle's Vileplume was sent out.
"Seviper, stop this crazy woman once and for all," said Jessie and Seviper was sent out.
"Use Stun Spore," said Jessebelle and Vileplume used the selected move which paralyzed Seviper.
"Seviper use Crunch," said Jessie and Seviper used Crunch which damaged Vileplume whose defense fell and then Seviper got rid of the paralysis with its ability, Shed Skin.
"Solarbeam," said Jessebelle and Vileplume prepared for Solarbeam.
"Use Poison Jab Seviper," said Jessie and Seviper gave lots of damage to Vileplume by using Poison Jab.
"It was then, Vileplume unleashed Solarbeam and gave Seviper lots of damage.
"Flamethrower," said Jessie and Seviper used the move of choice which knocked out Vileplume because Flamethrower was super effective.
"If that's the case," said Jessibelle as she returned her Vileplume, I'll just kill you myself," and Jessebell started to attack Jessie only to be stopped by a Flamethrower that came from none other than James' Growlithe and Jessibelle fainted.
Meanwhile, Ash and Serena were battling Jessebelle's parent with Gible and Delphox and were victorious because Gible evolved into Gabite and learned Dragon Claw.
After Jessebelle's entire family was defeated, an Officer Jenny arrived and took them all way.
"James," said James' dad after Jessebelle's family was taken away, "Your mother and I are really sorry for everything that has happened here." "We were so focused on our money, we gave you a terrible life."
"At least you both learned your lessons before things got worse," said James.
"There is one thing," said James' mom to Agatha, "How did you know about that secret plan?"
"I told them after finding out myself," said a butler who joined the conversation.
"Filbert," asked James' dad, "You knew about this?"
"I knew for quite some time," answered Filbert, "But I also knew you wouldn't believe me if I told you." "So, after learning about Team Phantom, I joined them and explained the problem to Agatha who promised to help."
"Well James," said James' mom, "It seems you have those who will help you now." "Also while we're at it, your father and I decided to give you and Team Phantom every last bit of our fortune." "We hope you use it a lot more wisely than we did."
"But you'll have nothing," said James.
"Sometimes, having nothing is better than having everything," explained James' dad, "We learned that the hard way."
"Then I'll take it," said James, "I would also would like it if you would be okay if I joined Team Phantom as thanks for saving me and start dating Jessie who I just realized I love after she confessed to me and protected me from Jessebelle."
"We are happy to let you do both," said James' mom.
"Do you really love me James," asked Jessie.
"I do," answered James, "But do you love me Jessie?"
"Yes I do," answered Jessie who then kissed James on the lips hard.
"Well now that that's settled," said Ash, "Let's go rescue my friends."
"Your friends are in trouble," asked James after the kiss ended.
"Giovanni has captured most of Ash's traveling companions except for me, Max and Bonnie," explained Serena.
"Then we'll both help you," said Jessie.
"I was hoping you two would," said Agatha," Also don't worry about Meowth, he already joined us and is acting as our Pokemon Translator and Master Mechanic.
"That's good news," said James who was glad to know Meowth is also onboard.
"Meowth will be taking a helicopter here to pick up James while everyone else will teleport back to headquarters," explained Agatha.
A minute later, Meowth arrived in a Team Phantom helicopter and picked up James while all of the other members of Team Phantom teleported back to headquarters.
