The other problem is everybody knows that Anakin is going to have to get it on with a queen sooner or later, in order to create a princess.
Which brings me to another poorly thought out point. Obviously princess Leia was a princess in the first movie, to add that kind of fairy tale or fantasy charm to space in the first Star Wars movie. I think it worked, even more so since the princess turns out to be a bossy pain in through much of her time with the heroes.
Now her is the messed up bit that I rarely here mentioned (here's one for you Gaffer), it is common knowledge she is a princess. Luke knew about her judging by his reaction, "The PRINCESS? She is HERE?" So she is a public figure in the galaxy, and it is common knowledge she is a princess... but why?
Seems like the fine citizens of the galaxy would be asking, "Ehem, what exactly makes her a princess again?"
And the response? "Oh, well, you see, her mother was at one point a queen of the planet Naboo, she died and a friend of hers, the Senator of Naboo and his wife, decided to adopt her... but just make sure you don't tell the Emporer, something about his right hand man being the father and would want to turn any children he might discover he had to the darkside."
Kind of funny Vader would never ask, "Hmm, this Senator Organa, who is always giving me trouble, and who used to serve in the Senate with my wife, has an adopted daughter who is a princess. Not too many planets have monarchies these days, I wonder where she is from... Interestingly enough, Padme was a queen, had she not died while nine months pregnant, which I assume without any questions asked, means the nine month old unborn child inside her perished as well, our baby would have been about that age..."
Seriously, this is every bit as bad as hiding Luke but leaving him with his real surname.
Kind of makes you ask the question, why did George even make Amidala a queen in the first place? Seems his original intention was that Leia was the real flesh and blood daughter of a Senator, which in his world, made her a princess. Honestly, this works for me no problem. Why didn't he just go with this for the PT? In trying to add more sense to it and make her a princess because her mom was a queen, he has really made things worse.
