Well I got mixed opinion with this. Not that I hate Citron and Eureka, but it is much better if Satoshi and Serena have an older companion like Takeshi. Maybe this time an older girl like Viola or Pansy. On the other side, I think it's also good that Citron and Eureka were their companion and Satoshi would be the matured one on the group *Rewatched the previous episodes* ..........W-well okay he's getting there but the point is, this is the perfect opportunity for him to be the leader of the group. That way, he can show the rest that he can take good care of them especially Serena.
I'd like to note here that the show often equates maturity with height. Professor Oak towers over Ash in EP001, Brock was taller than both Ash and Misty (and Misty was a little taller than Ash), and Brock maintained the title of "Tallest in the group" until he left and Cilan took over. And Cilan was the most mature of the BW Group.
Now,
Ash himself is the tallest in the group (not by a large margin over Serena, but by a notable amount over Clemont and lol taller than Bonnie). I agree that this is a good opportunity for Ash to act like the matured leader of the group. Hopefully we get more actions like in XY002 when he was all heroic and awesome... Maybe in the upcoming Malimar Episodes?
Ash being the most mature in the group also makes me hopeful for AmourShipping. Maybe his maturity will bleed into other areas of his life? (hint hint?)
But difference is that May joined Ash in AG01, while Serena joined the group in XY 07, so technically speaking, she still got a few more episodes to decide what she wants to do lol. Whatever it is , I'm sure it'd definitely benefit Ash and Serena interactions. I still think the writers want to take it slow about Serena deciding her goal and I don't mind it at all, but just saying.
That's true, so Serena has until XY21 to decide by that count. We don't know what episode that'll be yet...
I'm greedy, but I want her goal to be something that'll keep her travelling with Ash for a while. Maybe her goal will have something to do with Mega Evolution, which doesn't occur in the games until the 3rd Gym Battle?
And I still think you all are selling Clemont/Bonnie short. I don't feel like this is a similar situation AdvanceShipping found itself in with Max being a virutal impediment. We've already seen Clemont and Bonnie get out of the way. If our observant scientist notices something odd about Serena's behavior, I feel like he'd be the first in line to help her with her Ash problems. And if Serena and Bonnie spend more time together, the more time they have to potentially talk about Ash while he's not within earshot.
