“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.”
