Luke - "Leia, do you remember your mother? Your real mother?"
Leia - "Just a little, she died when I was very young"
It's not "Do you remember your mother? Not your real mother, you're adoptive mother, Bails wife"
So where you all get that she is remembering Bails wife is beyond me.
As some else said in a thread elswhere "Have you even seen these film?"
Besides I remember things from my childhood that I can't really explain.
Jesus, not everything has to be spelled out in front of you to make sense.
