I got a question.
If you were in charge of the anime and you were going to have Misty rejoin Ash how would you make her comeback?
I would have Misty's sisters return and be gym leaders again, then Misty tells Ash that she is not gym leader anymore, then Ash decides if she isn't doing anything join him again. Then when Ash is done Unova have him continue on his journey and have Misty as the main character of the show and write off Ash.
Also when she joins Ash she will be wearing a new outfit that would look stunning
