Ah.

Well, that is an important and rather crucial bit of information. Aziraphale thinks to put a pin in it because there's a bit more he wants to investigate, but he doesn't intend to breeze by the way that Crowley is looking at him now.

He lets his hand fall down Crowley's jacket sleeve, moving to instead to loosely wrap his fingers around the demon's. There is a slight tremble to the angel's fingers as he does so, obviously still nervous about initiating any kind of contact between the two of them.

"No, no! Of course not," Aziraphale answers him quickly, his tone light. He makes a dismissive gesture with his free hand before continuing on. "The first time was an unfortunate mishap. I practically exploded the entire thing."

Conveniently, he chooses not to mention how.

He lets out an annoyed huff of a breath and a makes a face. "Head Office couldn't stop making little quips about it either," he further explains. This is entirely true, but Aziraphale is also leaving out the part where many of the other angels also accidentally destroyed their first vessel as well.

It's no wonder early humans were so conflicted about what angels actually looked like.

"And I certainly wasn't going to tell you, my sworn adversary, that I blew up my own vessel. Can you imagine how insufferable you'd have been?"

Oh, he'd have to hear it from both ends. Absolutely not.
