Royal Bee says the photo she has of her friends in the diner is years old, but given that they are millennials, have they really been wearing the same clothes since they were teenagers?
Where are everyone's brothers? Boys like King Bee are completely absent despite their sisters appearing.
What's up with the Movie Magic characters? Do they really have two younger sisters? Spirit Queen never appears with Witchay BB in the series.
How old they are depends on how old whoever thinks they're supposed to be, so it's probably more Vague Age, as, other than the Tweens and the Baby Steps line, it's not said how old they are besides that some of them (the OM Gs and the Big Sisters, particularily) look older than the originals or whichever series that came before.
