Darth Vader finally returns to Tatooine for the first time since his mother, Shmi Skywalker died at the hands of tusken raiders. After cutting off the hand of his son, Luke Skywalker, at Bespin, Vader decides to go on a mission to track everyone who hid his son from him. His first stop was the Lars homestead, where his step-brother, Owen Lars, took in Luke as a baby and raised him.
Notice how Vader didn’t want to see the headstone of his mother Shmi? I wonder if he still hates sand.
