Crowley isn't worried about other people looking. He's not exactly ashamed to be with Aziraphale, far from it, if anything he's proud to have such a handsome angel on his arm, but in normal cases he does prefer not to come off as too soft. This isn't one of those times. This is a demon needing his comfort angel, needing to make sure he's really there beside him, not going anywhere.

Crowley nods, "Yes, that and the other person's memory." he mutters, his face pressing into the angel's neck as if he could hide there. "Just reminded me, you know, of all the times I nearly lost you."
