Question: How come this movie barely showed anything about Luke and Leia's mother? Luke doesn't even ask anyone what her name was (maybe that was hidden from Leia, but he can probably guess that Yoda or Obi-wan would know). I know we can assume that she was discussed off-screen, but they could have revealed a little more about her.
Question: When the rebels talk about the "forest moon of Endor," is Endor the name of the moon itself or of the planet it orbits? The initial description makes it sound like it's the planet, but later on they refer to the moon as "Endor." Which is it?
Question: Why doesn't Leia see Yoda, Anakin, and Obi-Wan's ghosts at the end of the movie (if she does, she doesn't seem to have much of a reaction to it)? I know she hasn't been trained yet, but when Luke was on Hoth (in Episode V), he was able to see Obi-wan's ghost before he had any training, and he heard Obi-wan talking to him during the attack on the first Death Star.
Question: I've read that in the expanded/extended universe books, Palpatine has a son named Triclops, who he was disappointed in. Why didn't he like him? Why wouldn't he want to try to train his own son instead of spending time trying to get Vader's son to join him?
Question: If Vader wants to kill the current Emperor, and become emperor himself, why does he not let Luke kill him? I am thinking he needs the Emperor to convert Luke to the dark side.
Question: How did the Emperor know that the rebels were going to destroy the new and improved Death Star and that other rebels were going to Endor?
