well, apparently, that's what we have to think now
butthere's no point in Luke asking about her.
Luke specifically wanted to know about THEIR mother....
that's why he asked... why would he give a fuck about her adoptive mother? he knows about his father, now... he wants at least one little thing that he can know about his mother... he just learned practically that Leia was his sister and this is the first chance he's gotten to tell her alone, away from everyone else... so he has to ask Leia for it... that's why he was so sad at her response... because he knew, now, of the tragedy of his father, and now, the tragedy of his mother.
so, yeah, it's easily explained away... given this new information... but it shows, yet again, that Lucas is a bad writer, even beyond his hokey lines...
dont' get me wrong, tho, i liked this movie alot.
the CGI might have been TOO perfect, especially in the Yoda-Palpatine part... and this was the best of the prequels... and arguably, imo, better even than RETURN OF THE JEDI.
