I…
I don’t know.
*breaks down sobbing*
I DON’T KNOW!
*ahem*
I have, in fact, tried before to think of an explanation for this. I inevitably come up with something that makes sense, but is completely out of place in the setting. It’s not just that they have a close family resemblance, because a lot of them aren’t actually related by blood (the Cerulean Jenny, I remember, is the sister-in-law of the Viridian Jenny – they could also be related by blood in addition to being related by marriage, but it would have to be a fairly distant connection like second-cousin, otherwise they’d mention that relationship first). I am unwilling to entertain the possibility that they are a legion of clones, because this is completely out-of-step with the way the world is generally portrayed. I am forced to conclude that they refer to each other as ‘sister’ because they are members of two secretive monastic orders dedicated to medicine and law enforcement, respectively. They ritualistically give up their own identities when they join and surrender their whole lives to the order, and must wear special makeup and clothing to suppress any distinguishing facial features. They have held the contracts for staffing the nation’s Pokémon Centres and police stations since the Pokémon League began, maybe even longer, and their traditional methods produce the most elite nurses and policewomen in the world, whose entire lives are utterly dedicated to their work.
…yeah, this is one aspect of the Pokémon world I’m pretty sure we’re not supposed to take seriously.
