Questions about Zauriel ?

Ok this time I have a question about zauriel on new earth he is male but in prime earth he is female how did this happen ?

@kid_omega_prime: Retcon

@thearchon: so dose that mean that there two separate beings then ?

@thearchon: @kid_omega_prime: 2 separate beings so that would mean there would be 2 zauriel's then ok ill play if prime earth one is the female then where is the new earth one ?
