Ronan can't figure out where Kylo's going with this. He's certainly not apologizing. He's not even, to Ronan's mind, implying an apology. And Ronan knows damn well that his own apology means nothing to Kylo, so it's not forgiveness, either.

What's most important, though, is that Kylo's speaking in the present tense. These sins aren't so vile that he can't bear to put his mouth on Ronan's skin.

Turning his head, Ronan looks over his shoulder and slides his miserable gaze to Kylo's eyes. He utters weakly, "You can't be a mistake. A mistake is something you do, not something you are."

It took Ronan a while to learn the difference, too.

"Hurt me if you think I deserve hurting. If you don't, then... don't."
