Back on topic I guess Flo being 0+ proves this stuff isn’t related to Rh- status. 
Wanderers are everywhere.
Edited to add that wasn’t an attempt to insist Flo is a wanderer if she thinks she isn’t.
Just that wanderers are in all races and some races are nearly devoid of RH- individuals so there must be Rh+ wanderers too.
