Prior to the climactic final fight in Return of the Jedi, Darth Vader senses Luke on the shuttle approaching Endor, but the Emperor does not. Why?
Prior to the final climactic battle above and on the surface of Endor in Return of the Jedi, Darth Vader is able to sense Luke approaching in the shuttle, but Emperor Palpatine is not able to and finds himself surprised by this. While viewers know that there is strength in the connection between Vader and Luke, it is surprising to learn that the Emperor himself cannot sense Luke on the shuttle, despite revealing just moments later that he has foreseen the fact that Luke will come to Vader willingly, before then being brought before the Emperor himself. Despite Palpatine failing to turn Luke to the dark side, there are a number of possible different reasons for Vader’s connection to Luke that bring the characters together.
Set against the backdrop of space, Star Wars is home to one of the greatest space family stories of all time. At its core is the eternal struggle between the Dark and Light sides of the Force, which has manifested itself through the Skywalker family onscreen. In the third installment of the original trilogy, Return of the Jedi, viewers see this struggle come to a head as Luke Skywalker battles to save the soul of his father, Darth Vader, while paving the way for his friends to defeat the Empire and the Emperor himself. Although the original plan had Vader not being Luke’s father, this was arguably the central story to George Lucas’ original space opera.
