...only Padme found out why Anakin seemed to leave the light. She became afraid for him, realising what he had to do to get so close to the sith that he would now be trusted.. he planned to betray the sith and destroy him, it was the only way he saw. All for the galaxy, the fight against tyrany, For his Wife, his child.. His heart was Full of Love for her still and he pleaded with her to see, Padme: come away with me while there is still time! Anakin: Don't you See? We don't have to run anymore! I can DESTROY him Padme... (Anakin had lost faith in everything by now, except his faith in the Force and his Love for his wife and unborn child) ...Obiwan never found out any of this.
