In this moment, like a few small other moments, Grey is struck by the fact that Cinna is just that bare few inches shorter than he is. Grey's cheek rests against Cinna's temple. He doesn't close his eyes as they sway; he is never one to let his guard down that much around other people. But Cinna can feel him relax, just that little bit when Grey's body is pressed to his.

This way, too, Grey can breathe in how Cinna smells, warm and spicy; it sends tingles down his belly. Cinna - how he feels and smells and tastes and looks - means everything, really. So, Grey breathes that in.
