Aziraphael's hand tightens on Crowley's without the angel fully realising; he isn't surprised, per se, but the change from a day ago is startling. There's real colour in Crowley's face, real liveliness in his eyes, in addition to the very real heat in his touch.

His hand slides over Crowley's shoulder once again and down his back, then the arm goes around his waist.

His smile only widens between kisses.
