There has been discussion about why Owen hates OB1 so much. It got me thinking. What if he was fulfilling a promise to Padme by keeping Luke away from OB1. It is possible that Padme blames OB1 (and the whole Jedi order for that matter) for Anakins downfall. Maybe it is Padme who drops Luke off to Owen and Beru. She knows OB1 followed her, wanting to watch over Luke. So she leaves the Lars homestead with strict orders to never let OB1 near her son. It is possible. She could feel it is the only way to protect her son from the dangers that he might face by joining the Jedi order. What do you think?
