Gotcha. I was going to argue that with his parents dead (or presumed dead), the Larses would be the closest thing to a family to Luke anyway, but then I remembered that Padmé’s parents would fit that description much better. 😃 Of course their existence in Lucas cannon is questionable, since they only appear in a deleted scene.
Ugh. Now we need an edit that would make Owen or Beru blood-related to Anakin. 😛
