It's because we've done this song-and-dance before. Across worlds. But you don't know that. You can't know that. Genesis thinks, a touch bittersweet in his own head. He doesn't bring it up, either. Cloud is confused by just the feeling of enjoying a kiss with him; there's no way Genesis can drop that sort of information on Cloud, and not expect him to sink with it.

Genesis is much better at acting than Cloud, thankfully, and doesn't drop his mask even a little. At least, not outwardly. The confused longing is met by that same powerful, predatory approval. And while he doesn't sink his fangs in right away, Genesis hooks a claw in him. Mirrored by the way he tugs Cloud by the collar, and brings himself lower and closer.

"Don't think too hard on it, little storm. It felt good, no harm came of it, and I won't even spill your secret if you don't wish." Again, in his own mind, Genesis privately sighs about the fact it's not a secret to plenty of people in their lives. But if the offer makes Cloud feel more secure in his impulses, so be it. "As for familiarity... well, isn't there plenty about your life that is a mystery to you? These sorts of knots tend to unravel themselves in due time."
