I'm a big fan of the "Bloodline" novel by Claudia Gray, but one thing doesn't make sense to me.
Bail Organa a member of the senate, a rebel, an intelligent man, who knew Leia better than anybody else for over 16 years, did hide the biggest secret of his daughter in a wooden chest. He knew that his daughter isn't a fan of rituels and nobility and he even foreshadowed his own death, but he hid the secret, that Darth Vader is Leias father, on a distant planet, where Leia needs to be the Govenor of, to get this chest. Why didn't he hide the secret somewhere else? Or atleast tried to protect it with any security stuff or smth?
