"Of course not," He said dryly - unlike Crowley though, Aziraphale was a little more aware of things like that. But truly the temperature wasn't really the temperature wasn't truly something he couldn't deal with, just one small miracle and he was fine.
More interesting than the weather here though was the mystery of these doors, a little like what he'd felt in coming across the prophecies of Agnes Nutter, though perhaps with not quite such potentially Earth ending consequences. Which only served to make it better really - a mystery that wouldn't end in the end of everything? Much preferred really.
So here they were, on the edge of something new with the one other being in existence that Aziraphale would have wanted to share it with. "Oh now that would be just right," He agreed with a small pleased smile at the suggestion of a bookshop. He missed his shop, missed the books he'd spent so long collecting and guarding as bets he could. And now here he was with none of it.
But they had this ahead of them, the potential for something new and exciting and he hadn't felt this interested since the Rosetta stone.
"Only one way to find out though," He reasoned, and decided there was no better time to find out than then. Taking just a moment to see if he could feel any particular energy from any of the doors they had to choose from only to come up with nothing to show for it and picking one at random, pulling the door open and stepping through it and into another bright sun shining sort of day. He lifted a hand to his eyes to try and shield his eyes from the light just a little to take in what they were walking into - not dinosaurs it seemed, or more depressingly a bookshop.
