In Star Wars - Episode IV: A New Hope, Han takes his reward for saving Leia and leaves Yavin before the Rebel Alliance sets out to destroy the Death Star. At the last moment, when Luke is on his attack run and Vader is about to shoot his X-Wing down, the Millennium Falcon appears and gets the TIEs off Luke's tail.
Whose initial idea was it to go back and help the rebels - Han, or Chewbacca?
Note: This question was inspired by the new canonical novelization of the movie, titled Star Wars- New Hope: The Princess, the Scoundrel, and the Farm Boy, in which Chewbacca clearly wants to join the rebellion, but is overruled by Han.
And after the deed is done, we read:
Han shrugged. “Well, I wasn’t gonna let you have all the credit!”
Chewbacca growled behind Han, giving the captain a little shake.
“All right, all right, and because we wanted to make sure you got out of this mess in one piece!” Han said.
