it is true that they are two different people. and no, lucas didn't completely discredit the eu. bail antillies is the man that ruled alderaan before the clone wars. during the clone wars, dad served under him, and not only proved himself a good fighter, but a capable leader as well. during the war, something went terribly wrong, and bail antillies was killed. once this happened, my dad, bail organa was elected to take his place. you must realize that there are about fourty years between episode one and episode four. a lot can happen in that time.
