As I am sure most of us non-donkey riding folk here on SFF are familiar with...
- Princess Leia was traveling on the Tantive IV trying to get the stolen plans of the Death Star back to Alderaan and picking up Obi-Wan up long the way.
- Princess Leia is so named because she is part of the royal family on Alderaan.
- She is also a member of the Imperial Senate (which is located on Coruscant).
Why would Leia claim she was on a "diplomatic mission" to Alderaan?
Real-life example, would a Senator who was in Washington claim he was going on a diplomatic mission to his home state? I understand inter-planetary travel is over much further distances... but still Leia was just "visiting home".
This also makes less sense when you see where Coruscant and Alderaan are located in relation to Tatooine... Coruscant and Alderann and practically next door neighbors in Galactic terms while Tatooine is in the Outer Rim.
Regardless of the real reason they went there... should she have claimed that she was on a diplomatic mission to Tatooine instead, to make ruse somewhat believable?
It makes even more suspicious that the Death Star was being built near Geonosis and guess what, Tatooine right next door!
What was Leia's reasoning behind being near Tatooine when she was supposed to be going to Alderaan?
