To be honest, what do we really know about Showcases? Can we really say its just a girl thing?
And you guys say that Ash might not be interested but we can say the same thing about him and contest but he still participated in one or two. (dont remember the exact number)
I dont think anything is stopping him from wanting to try it out for himself at least once especially if it is to help a friend. =)
It's been confirmed to be a girl's only thing. I didn't want to post my reply in the thread since it's offtopic. And I'd rather not see Ash take even more screentime away from Serena like he did in the 1st year of XY, so I love the girls only rule.
