Yeah. In X&Y when you get Diancie a maid and butler come to take it from you. But then an older guy says stuff about the magic of friendship and you keep it.What is this? When you bring Diancie into X&Y theres like an in-game event?
This repeats a little differently in ORAS where they try to take it again, but this time a karate guy comes and gives you a mega-stone instead (and you keep the Diancie too of course).
