why does whitney have 2 pokemon when bugsy has three, even though that is in the original, and why do leaders such as Falkner have higher level pokemon, and then whitney has lower level pokemon?
Please note, it is possible that the information changes by launch but it is not likely. It's also probable that we don't have complete details on the activations of the main details within this update, so it's best to be cautious. (This corresponds to the legends, starters & misc info)
