“For a long minute he gazed at her, his eyes searching the features of that face he'd grown to love so deeply over the years, his memory bringing up images of the past as he did so. The young determination in her face as, in the middle of a blazing firefight, she'd grabbed Luke's blaster rifle away from him and shot them an escape route into the Death Star's detention-level garbage chute. The sound of her voice in the middle of deadly danger at Jabba's, helping him through the blindness and tremor and disorientation of hibernation sickness. The wiser, more mature determination visible through the pain in her eyes as, lying wounded outside the Endor bunker, she had nevertheless summoned the skill and control to coolly shoot two stormtroopers off Han's back.

And he remembered, too, the wrenching realization he'd had at that same time: that no matter how much he tried, he would never be able to totally protect her from the dangers and risks of the universe. Because no matter how much he might love her--no matter how much he might give of himself to her--she could never be content with that alone. Her vision extended beyond him, just as it extended beyond herself, to all the beings of the galaxy.

And to take that away from her, whether by force or even by persuasion, would be to diminish her soul. And to take away part of what he'd fallen in love with in the first place.”
― Timothy Zahn, Star Wars: Dark Force Rising
