There are only two choices: She leaves Kalos with Ash to go to Kanto or just stays in Kalos.
There's no way that she will confess or Amour be made canon at the end of XYZ. Even then only 'Serena in Alola' would mean that it's implied canon, which the writers will never do. That means, they have to have some other Pokegirl balance it all out if Serena ever does leave Kalos.
We'll just have to wait till next week or two. They could have some specials or something planned after TF arc.
>>28324696>>28324789The main flaw of Amour is that Serena just can't form a strong bond with Ash. The closest is people knowing of her crush and supporting her in it, but they don't do anything else. But they never say about how Ash and Serena have a strong bond, because it doesn't exist (despite how Amourfags claim otherwise). Serena is just too passive to do anything, and she's delusional in regards to her relationship with Ash.
