>>57076194From what I can remember: The first time the event was on you needed to complete one part of it first before getting the other (Guzma and Jasmine or Diantha and Hilda) and you got one or two golden balls at the end to unlock the last part of the story. But since it's rerun you can do everything and so you get all the balls (or bronze ticket) there were a lot of events like this in past
