Rey snapped.
"This is why you've been gone all this time? This is why the resistance has floundered, why Snoke has been unopposed? WHY HAN DIED?!" Rey choked back tears.
"Because you've been moping about on this godforsaken island unable to come to terms with the fact you failed?!" Rey's vision became a hazy red of fury and anguish.
Luke stared at her stonily. "No, not because I failed. Not because I considered murdering my own nephew in cold blood."
"But I have given to this galaxy and the force more than you could possibly imagine. I spent years of my life trying and trying to bring balance, help others, restore freedom. And for what? There's always another threat, another evil, another 'empire'. It never ends. The only constant is the fear, the anger, and the suffering. I've lost family, students, friends-"
Luke's composure cracked. "When you see your pregnant wife, murdered before your eyes by the very pupil you trained and loved… You stop being 'Luke Skywalker' anymore. You stop caring, you stop feeling – what's the point? The universe and the galaxy can all go to hell, and the Jedi and Sith along with it. Once upon a time if 'Luke Skywalker' could have given his life to save Han's, he would have.
But Luke Skywalker doesn't exist anymore." Luke turned away and went back to his hut.
