Of course- Aziraphale had seen things to, and if the theme of the memories were tragic ones, Crowley was curious what he might have seen. His head tilts up to look at Aziraphale from his shoulder. He thinks he knows what the angel might be referring to, but doesn't want to assume.

"What do you mean?" he asks, voice cracking slightly, thinking about that day in particular, about how many times the angel had outright rejected him. Aziraphale had always said no the first time to things, that was normal, but that day he put his foot down, and Crowley really felt it. Like a shot to the heart, even. He had made a choice in that moment, and that choice wasn't Crowley. The demon didn't want to be reminded of it, but it was hard not to spiral down that train of thought.
