Agreed, except I'd prefer it if Alexa stuck around the group instead of her sister if the speculation about Ash, Alexa, Clemont, and Bonnie are to be proven true. Which I would be all for by the way. The group dynamic of four people hasn't been really done since the Advanced Generation and when it was, I loved it. I'd like to go back to that again for the X and Y Series and put Ash in the role of a mentor to Bonnie similar to how he was with Max. I would also like to see Alexa being sort of a mediator to Clemont and Bonnie whenever they're fighting, as a callback to her relationship with her sister.Well, I hope they break the long-term tradition of having one male and one female travel companion. There's nothing wrong with two girls or two boys is there? As well as that, I have a good feeling that Viola will be joining Ash very soon.
There's more diversity and opportunity for better storytelling when you have a group dynamic of four people compared to just three. When they range from different age groups like the speculation here, then it's all the better and gives viewers of different age groups something to relate to and look forward to watching.
Regardless of who gets put into the group though, I do hope the writers go with four people instead of three.
