Habits truly are hard to break. Riku still tensed a little when Ienzo came in, but the tenseness faded mostly with a silent sigh. Ultimately, he never became a vessel. And that meant he wasn't their major concern right now. And who knows? Riku was able to get along with Lexaeus. Perhaps out of the Organization, a former-Zexion could be an ally or friend. It was something Riku came to terms with not long after they'd spoken on Cambot.

As such, he gave Zexion a nod.
