I think that part of the dynamic with Miette was a fun gag that subtly puked fun of Serena's confidence issues and her proclivities for not taking the initiative. Again, people over focused on what were 5-10 seconds moments of Amour in what was mostly an episode focused on Serena's search for something to do.I understand what you are saying and taking a clearer glance Amour isn't shoved down our throats as much as I thought earlier but I will say that the writers refuse to let us forget that she does have one him. A good example of this is Miette in her debut episode where Miette realizes that Serena has a crush on Ash and while that isn't the focus of their rivalry it is jarring.
First, as I've said, I don't think there's anything wrong with the idea that her development is intertwined with Ash.Can Serena not have one aspect of her development that isn't intertwined with Ash? Why does Miette have to be her "rival" over Ash as well?
There are plenty of aspects of her development that were explored that weren't directly intertwined with Ash. Episodes like #47, #50, #53, #60, and #64 among others are developmental episodes where Ash and Serena's relationship isn't the focal point of the episode at all and instead explore Serena's character through several different facts whether it be through her relationship with her Pokemon, her dynamic with Aria, her relationship with her mother, her failures with showcases, etc alongside her relationship with Ash.
That's not really why she left. Seeing Ash was her excuse to leave the house and start her journey because she didn't want to do Ryhorn Racing as she tells her mother that twice in the series.Serena leaves the house because she sees Ash's on TV and decides to return something of his
I don't think that's remotely a fair interpretation of why Serena had Fennekin.Serena obtains a Pokemon to chase down Ash
I don't think it's a bad thing that Serena went on a journey on self-discovery that led her to finding what she wanted to do in life just because Ash invited her too.Serena goes on a journey because Ash asked her too
Even there, it's also Shuana who is also an influence on Serena and not just Ash.Serena remains undecided of her goal and wants to find one after seeing Ash and Shuana profess their dreams
I don't think it's true at all that in the show that more of their rivalry was focused on Miette teasing Serena about Ash in the anime. I mean even in your post you agree that's the case. Miette in many ways is the opposite of Serena in how Miette is confident where Serena is not and using Ash to showcase that dichotomy was a great gag that the anime used to highlight that difference.Miette a rival of Serena spends more time teasing Serena about her crush than actually competing against her in Showcases
I think that the battle with Ash was one of the many factors that led her to make the decision she did and it's characterized so in the anime.Serena is able to make a decision on what she will do after life after having a battle with Ash
There are plenty. That doesn't mean the anime isn't going to ignore Ash's influence on Serena and their relationship since it is one of the driving forces of her character and that's a good thing not a bad thing.There is more but I can't think of at the moment. What I'm saying is that if would of been nice if she had some form of development and or interactions that didn't intertwine with Ash.
