It wouldn't have mattered, that Han was there to save Rey. That he'd died doing so, that he wouldn't have been there if not for her, did not factor into his emotions. He had been there because that was how things had gone down. He had been there because the Force had willed it--though this, Luke was no longer certain he believed.

But however Han had come to be on Starkiller Base (whatever that was), it was just another in a long line of situations where anyone might have been killed, and his time had come.

"You're wrong," he said softly, squeezing both her hands in both of his and meaning it so much that he forgot about the metal of one of them. "No. Look at me, Rey. Whatever happened, whatever you're not telling me, you couldn't have made Han do anything Han didn't want. So any part you think you played in what happened?" He tilted his head. "He put himself there. If he needed your direction to get there, then that was what he was looking for. Not something you imposed against his will. Believe me. There is no doubt in my mind that he wouldn't trade having known you for anything."
