Well I was waiting for things to calm down in here before posting this so it doesn't lost in the pages lol. Anyway, this is my final thoughts on xyz47 and if Amour is canon or not:
When Serena tells Ash, "you are my goal," and "next time we meet, I'll become a more attractive woman," there was mixed reactions and some overreactions to this. For me personally, this was obviously Serena's way of confessing to Ash. Serena knew she was going to be leaving and didn't want to leave w/out telling Ash how she felt about him. I think she says this because it was a way for Ash to understand what she means by it. Gauging by his reaction, he was taken back by it, but I think he understood what she meant because of the fist he makes, which is like a trademark thing for him. Being a Serena fan first and foremost, I didn't like the attractive line at first because it undermines her character in way, like she's saying she isn't good enough for him, but then I looked at it from a different point of view. I think Serena may have been intentionally planting a seed into Ash's brain to again make him understand and the next time they meet, he'll look at her in a different light. The infamous wink came into play here too. Also, it could just simply mean that Serena was going to become a better overall person too.
So at this point, Ash kind of understands what Serena meant. As Serena is going down the escalator Ash steps forward to see her leave while the others stand their ground behind him. This was real interesting because it seemed liked the writers purposely put in Ash in that position to set up what was to come next. As she's going down, she probably thinks to herself, "I really do like him, ahh what the heck, let's go for it!" So she asks Ash for one last moment and Ash, Clemont, Bonnie, and Pikachu reacts "wait, what is she doing?" Serena runs up and kisses him and yes it was a kiss, most likely on the lips which is why they didn't show it and then the reactions to follow: The whole world is stunned, Clemont is stunned, Bonnie and Pikachu react, "Omg, that's so awesome," and before she leans in, Ash "wait! what is she...?" It happens and Ash is left in a dazed state, like he was in the Pokevision episode when Serena was in the costume. Serena is blushing like crazy and smiling and she says thank you. Ash's eyes are glistening, he sighs, and he smiles, which to me means he liked it. Was it enough for him to have romantic feelings? I don't know. Bonnie also with the wink and fist pump. The plane takes off and he makes the same comment he made when Serena lost her first Tripokalon, that she's strong and not to worry basically. I honestly would like to see if Ash tells his mother about this.
So does Ash have more than friendly feelings toward Serena? I think Serena holds a special place in his heart, but the extent of his feelings remains unknown still imo, which is why I can't fully call this ship canon yet. I mean it's definitely the closest ship to a canon state, but I would've liked to see a more blatent "hint" from Ash before saying it is. My heart says it's canon because of the way Ash has treated Serena throughout this series and I'm a hopeless romantic, but my brain doesn't. I apologize if that upsets people here, but I'm just being honest. If there was more genuine moments like the river scene, snowball scene, night after the Master Class, XYZ45, etc...I'd have different feelings possibly, but we needed more of those imo. Anyway, that's my thoughts, take it for what you will. I'll still be poking around in here from time to time to see what's happening.
