“Oh, me? I haven't slept much these past few days," Rey said quietly. "Too much on my mind.”

“Kylo had rummaged through these hopes and fears, things he had no right to. But as he searched, something had changed. Even as he callously rifled through her mind, he had somehow revealed his own. Rey found herself in his mind even as he invaded hers. She felt his rage, like a ruinous storm that filled his head, and his hatred, and his lust to dominate and humiliate those who wronged him. But she also felt his hurt, and his loneliness. And his fear -- that he would never prove as strong as Darth Vader, the ghost who haunted his dreams.
Kylo had retreated at finding Rey in his head -- had practically fled from her. But that had not been the end of that strange, sudden connection. She had seen more -- far more. Somehow, almost instinctually, she knew how he accessed some of the powers at his command -- even though she didn't understand them. It was as if his training had become hers, unlocking and flinging open door after door in her mind.
But now Rey couldn't shut those doors -- and she feared what had been set loose.
Kylo had urged her to let him be her teacher -- had pleaded with her, almost.”

“Kylo Ren knew who was in the escape pod even before it opened with a hiss of vapor---her presence had been a steady pulse from the Force the moment his junk-heap freighter once again somehow heaved itself out of hyperspace without disintegrating. The stormtroopers behind him stood ready, but he just smiled at the sight of Rey crammed into the pod's tight confines.”

“Snoke's escape shuttle is gone," the general replied.
Kylo considered that. Rey had recovered first. She must have realized he was at her mercy, yet she'd left him alive.
Almost as if she cared for him.”
