@Martha Elena Brenes Orozco I don't think they're identical, she is illegitimate unlike the other, she even called the other big sister or the otherway round, can't remember, and it is a coincidence that they look alike which is why she was even allowed to exist in the first place since she was meant to be used as a replacement, not that I don't know how they knew so far ahead in advance that they'll need a replacement...
