At the end of the day it comes down to these two lines:
After his greatest failure, Luke hangs from the side of cloud city, lacking weapons and a hand. Completely defeated, he calls for help… anyone.
After her greatest “failure” (this is her one moment of weakness so far) Rey escapes from the Supremacy, having failed to bring Ben Solo back. But her first line back is:
Yeah, I like this!
One thing that’s easy to forget apparently is that at the end of Empire, Luke’s back in tip top chipper shape (already has his hand back), confident and with a plan to save Han being his last line in the film. Whereas Rey’s last line in the film is one of fear and doubt.
