he should have had anikin walk in on jarjar doing portman, and that be the reason that anikin turned so dark, and jarjar being luke and leia's father would explain a lot about why they were so dippy to have such a strong father. but why would darthvader tell luke he's his father then? just to confuse him so he could cut off his hand, plus he's in denial that his wife would cheat on him with jarjar. I guess luke would be more shocked to find out jarjar is his father darth vader still had some good in him so he didn't want luke to know
