"Oh, that." Caught slightly off-guard, Aziraphale found himself fidgeting but dropped his hands. "Well, you know." That was a terrible answer and he knew it. Then again, he didn't truly have a reason. Not a good one. One that wasn't along the lines of 'The world was going to end' and 'They had work to do'. The list was quite long with various versions of said reasons - excuses, really - and none were viable any longer.
Instead, Aziraphale simply shook his head. "We haven't the time to discuss these bits and pieces. We need to find the others and get out of this awful place. I'm already going to have to have these shoes polished three times," he whimpered, frowning at the very idea.
"I believe these conversations are better suited elsewhere after all. Anywhere that is not these woods." There was a small grin on his face after he spoke, feeling a bit proud that he was, indeed, proposing he and Crowley have what mortals liked to call 'alone time' when all was said and done.
