Hey guys im gonna be straight with you, look as an amourshipper it hurts me the situation on the whole community but just relax about serena, i dont think that the writers are that cynics or stupid to put all the fandom over them so i think they will give us a conclusion that will satisfy at least half of the community, look i do even have a prediction for what may happen on the next episode so please hear me:
-Serena is aiming to become a kalos queen but she realize that she doesnt have to be in kalos to become a queen just like ash didnt have to become the kalos league champion to become a pokemon master so, serena chooses not to become the kalos queen but queen of the world making people smile from all around the world, but she has to do it all by herself because if she were to be helped by yashio (the writers are aware that everyone hates her) she would end up to be just like elle and serena may even think something like "who says that yashio could not do the same to other girl helping her to beat me, just like shes doing with me to beat elle?" of course she aint going to think it in that way but the point is, everything she will do is going to be done by herself besides she is confirmed to be for the last 2 episodes so she wont be leaving on her episode which pretty much confirm that at least her answer to yashio will not be a directly YES, so chill out people, about hints ash will give her indirectly what she needs to do and at least will be a hug (dont ask me why im saying this but i have a great good feeling about this)
