I don't own Pokemon, this is the fanfic is if Amourshipping is canon. I'm not guaranteed that it would happen, but we'll have to wait and see.
When Ash and Serena gone on their last date before they are getting married, Ash was going to brag about it to his friends, Ash visited Prof. Oak's lab and then found him, Tracy and Gary there, and then Serena remembered Gary when they were at camp, Gary ending up teasing Ash at young age. Tracy said "Hey Ash, who is this young lady?" Serena then said "My name is Serena, I'm from Vaniville Town, and Ash's fiancé." Gary then said "Aw, Ash, are you going to get married soon?" Ash then said "Well, I uh..." Gary wanted answers, he said "Speak up, you know you're blushing." Ash then said "Yes, I am getting married to Serena." Ash saw his mother come up.
Ash's mother said "Hi Ash, congratulations on getting engaged." Ash then said in embarrassment "Uh, Mom, I'm just uh..." his mom then said "Ash, you are engaged right?" Ash then said "Uh Yeah, I am." Gary was really happy for Ash, and so was Tracy. Tracy then said "That's great, when are you getting married?" Serena then said "Um, probably 4 days from now, at 9:30 P.M." Ash then said "Uh, yeah, that might be the date." Prof. Oak then said "Well that is great, Ash congratulations." Ash then said "Thanks guys, we'll see you soon." Ash then headed to Pewter City, when he and Serena are being watched by Team Rocket, who is in retirement.
Jessie then said "I see that those 2 are getting married." James then said "We gotta figure out what is going on with him." Meowth then said "Yeah, let's find out what is going on." Wobbuffet came out and said "Wobuffet" Pikachu was also watching Ash and Serena behind a tree, worried about Ash "Pika..." Pikachu said in a worried manner, When Ash and Serena made it to Pewter City, Brock's brothers and Sisters were wondering what was going on with Brock. "What is up with our brother and that woman." Ash was confused, he went into Brock's room, and saw him and Lucy.
Ash was frozen there like a statue posing. Serena then came in, and woke Ash up "Ash." she said Ash then said. "Uh..." then Brock saw Ash, Lucy also saw him. Brock then said "Stop posing like that." Ash woke up and then said "Brock, why are you with Lucy? She is a Frontier Brain." Lucy then said "Well, I heard a lot about Brock, I hear that he was searching for a girl for a long time, and he finally found one, and that is me." Brock then said "Yes, Ash are you excited." Ash then said "Uh yeah, congratulations Brock." Serena then said "Well I'm Serena, I'm Ash's fiancé." Brock then said "Congratulations Ash." Ash said while blushing "Uh thanks Brock." Lucy was also proud of Ash, "Ash, I see you found yourself a girlfriend, just like I found my one true love." Brock was blushing. However Crogunk was in the corner upset, about Brock finding his true love.
Ash said "What's Croagunk upset about?" Brock said "It is upset that I found a girl, and it can't laugh at me by poison jabbing me." Lucy then said "I heard that he has traveled with you for 4 regions straight. He is a good trainer after all." Ash then said "That's great, well we're planning our wedding in 4 days at 9:00 P.M." Brock then said "Alright, see you there." Ash and Serena left Pewter City, and then Ash was afraid that Misty would kill him, for thinking that he cheated on her, so he tried to hide it.
What Ash didn't know that Misty was watching, she was pretty jealous, she went over and just acted natural. "Oh, Hi Ash." Misty said "Hi, I would like you to meet my..." Ash then thought to his head "Don't say that Serena's my one true love." And lied "New Friend." Misty said "That is great, do you still have that gift I gave you?" Ash then said "Yes, I have your lure, here it is." He pulled it out, and Misty said "That is great, I knew you would remember me." Misty then said "So, what are you doing?" Ash then said "Well, we're going on a walk, talking to each other." Misty then said "Well, sorry for interrupting you, I'll see you later, Misty left, what she knows "Ash has found himself a girlfriend, and I know it.
Pikachu was under a tree crying, and Team Rocket was listening, James said "That sounds like a Pokemon Crying." Jessie then said "Well, we better check it out." they went over to the tree and saw Pikachu, and Meowth said "Pikachu what's wrong?" Pikachu then said "Pika! Pika!" Meowth said "What? The Twerp is going to get married and you think that you're going to lose him." Pikachu nodded, and then James said "What should we do?" Jessie then said, "Here's the plan, 1st we trap Pikachu, then act like we're doing no good things, and then Trap the Twerp, and then we'll take him away, then try to convince him that she is going to be bad news, the twerp would dump her. And we'll finish up, by having Pikachu reunite with Ash." Team Rocket then said "Can you trust us?" Pikachu then said "Pika!"
Ash and Serena then gone to see his old friends, before they get married in Alola. Ash saw Pikachu with Team Rocket, acting like Pikachu is kidnapped. "Team Rocket! What are you up to now. Enough with the motto." Team Rocket then said "Well, you want Pikachu, come and get us." Ash then said "Charizard! I Choose You!" Charizard then came out of the Poke Ball and then Ash said "Charizard, Flamethrower!" Pikachu then said "Pika!" Meowth then said "Ha! You fell into our trap." Then trapped Ash, and tried to take him away, but Charizard burned it immediately, and then Charizard burned the net, and then blasted the balloon and Team Rocket was launched in the air, and said "We're blasting off again."
Charizard then caught Pikachu, and then brought it back to Ash, and then Pikachu then said "Pika Pi." Ash asked what is wrong "What's wrong Pikachu?" Pikachu then said "Pika. Pika, Pika, Pikachu." Ash gasped a little, he said "You don't want to lose me?" Pikachu then said "Pika Pi." and nodded, he then said "I'll always be with you, even though I will get married. Pikachu then said "Pika." And smiled, they went back to Pallet Town to get some sleep.
