She was once Beru Skywalker, Anakins sister. She was never trained, but is force sensitive and can see things before they happen. She married Owen Lars who never agreed with such “wizardry”. She stayed behind with Owen while her brother left on an “idealistic crusade” with Obi-Wan.
Watch the films with this in mind and it works just as well as Obi-Wan’s twisting the truth to Luke.
For me, it makes the entire backstory more interesting as both Owen and Beru would be strongly connected to and involved with the plot of the PT. It would give an opportunity for a good female character and much better relationship dynamics.
This could fit well with a personal canon I have for Anakin.
Anakin Skywalker is a young star pilot who lives a regular farm life on Tatooine with no desire to leave his home planet and believes himself to be a normal person like everyone else, unaware that the Force is strong with him. He then meets Obi Wan Kenobi whose ship has crash landed on Tatooine and is able to see how strong the Force is with Anakin. He then explains to him who he is as a Jedi Knight, the Force, and his involvement in the Clone Wars. After hearing all this Anakin begins to learn about something much greater than himself and when offered the chance by Obi Wan to leave with him to be trained as a Jedi and fight in the Clone Wars he unhesitantly agrees.
His friend Owen Lars tells him he shouldn’t be going with this person on some “damn fool idealistic crusade” but Anakin tells him that this is what he believes in now.
