Wow, Serena's boring but you actually like Iris? You have stronger stomach than me...Honestly I Stopped watching X and Y because of how boring of a character serena, I still keep up to date on gym battles but it's because of how poorly the lead female character that lost all interest, so having Iris return will be nice, actually if they don't screw Ash out of losing and he gets a chance to battle the elite four, they could have it where Drasna is friends with Draydon and he and Iris are visiting, I would love to see Iris with new design, some like her BW2 but without the dress, I also doubt that she would be scared of fairy type pokemon or beaten by anyone in the group since
-Serena barely using her pokemon to fight.
-Clemont pokemon aren't as strong has her's.
-The only Pokemon that Ash has that could be her are, Pikachu and maybe Greninja if the whole Ash greninja is still a thing.
I would love it if Bonnie starts calling Clemont a kid after she hears Iris say to Ash, that would make me soon happy that people will say stuff like "OMG THEY RUINED BOONIE!!" because let's face it,Pokemon fans are whiny like that.
FYI, Clemont is a gym leader, Iris is a "gym leader some day when she's better" and honestly Iris will lose if that's what the writers want...
