This has bothered me for awhile, and I cant seem to find anything other than speculation on why Luke was been " Hidden from his father" yet was given his last name. The book Dark Lord goes into a little bit about Ben looking over baby Luke, and after a holovid, discovers that Anakin had indeed survived the duel. But this does not, as the films do, truly explain why Luke is a Skywalker in name. Based on events from RotS, where Yoda tell Obi Wan that he hopes the twins can destroy the Sith(they believe Anakin to be dead at this point in the story), this could possibly be one reason, although Palps would surely recognize the Skywalker hertitage if by chance he were to discover it. Was it just normal for the Lars to give him his birthrite? Did Obi Wan say anything to them at the end of RotS? We see nothing in the films that would support that he had told them or suggested Luke was to keep his fathers name. In theory I can only speculate several options: 1: Tattooine is a remote planet, far the empires grasp. This option doesnt cut it for me, its to risky. 2: Obi Wan, nor Yoda, suggested that anything be mentioned to the Lars, the Lars chose to give Luke his birthrite. This option is very likely, although, haveing Ol' Ben around to protect Luke, suugests that the baby could be in danger, so why advertise Luke to the Sith? 3: The Jedi, Ben and Yoda, wanted Luke to have his name sake, knowing that the Force will one day bring Luke to begin his own journey, his own destiny, and knowing that neither Obi or Padme could appeal to Anakin in the end, Luke would only be able to follow his own path and cousre in life as Anakins son, and truly walk in the footprints of his father, as we see him do in so many aspects. I think this option is about as spot on as you can get, I would like to hear any feedback on this, or anyother of the options for that matter. 4: The Jedi anticipate Anakins weakness and hope that Luke Skywalker will appeal to whats left of Anakin Skywalker, also known as the "redemption theory" that many of you have heard about. Through the Force, the Jedi find out that the Chosen One can return, and follow his destiny, and destroy the Sith, as only he can do. This option is also possible, however, there is not a whole lot of evidence to support it, but the general opinion of many fans beleieve the this is a likely scenario. After watching Ep. 3, and during the events that unfold, in the end, why do we not see an answere to this? Is there something we are missing?
