I agree with Eva, the hug was not that of a mother to a long lost daughter. It was a knowing hug of a friend of a mother or just a “you are the only other woman in this franchise” hug.
I would also say that the only truly balance Skywalker in the franchise is Leia, who grew up as a Princess. The saver thing to do would be to have her adopted by a royal family. Of course, then that planet would have been one of the ones that was blown up by the new Death Star.
