They look the same because it's all the same person when it comes to body/physical part, we just see them a bit differently because when someone has split personality disorder (a supernatural one in this case too) every personality acts, dress etc differently, some can even speak different languages, be deaf, have diabetes despite original person not being ill etc.
But yeah, whoever of them remain at the end I'll miss the others honestly (in case that they disappear, we'll have to wait and see lol)

Wtf, why make them all look the same with diff personalities and make only one endgame? ARE WE FR? WHY MAKE ONE ENDGAME IF U CAN JUST FUCK ALL.
