Why did Leia stop to pick up an elderly Jedi, anyway?
Imagine you’re Princess Leia. You’re a member of the Imperial Senate who has just committed treason. Rebels, who were financed and equipped by your father, have just stolen secret blueprints for a planet-destroying superweapon from a fortified government archive during a heated battle. At least a dozen of your own crew died just trying to get these blueprints onto your ship, all killed by a 2-meter tall cyborg wizard in black body armor. The same guy who literally just watched your ship narrowly escape him and jump into hyperspace. As per your father’s instructions, you are to bring the stolen plans to Alderaan, where your planet’s brightest minds will scrutinize them for a weakness.
But before you do that, dad asked you to stop by some dirtball nowhere planet and pick up an old man who used to be a space-cop.
