"Me?" Aziraphale scoffed at the very suggestion, as a former agent of the Lord God he certainly did not make mistakes, and certainly not any that would land them somewhere that was very much not Earth by the feel of it. Alpha Centauri certainly had not changed this much since the last time he'd seen it and well where exactly where the crepes?
"No, no I had nothing to do with this," He shook his head at the mere suggestion that it might have been him. After all he would know if he'd done something like this.
He frowned, this was not at all where they were meant to be, even if there were crepes to be had, and from what he could see there certainly were not. But it was easily fixed, they could sort out exactly who was to blame for this cock up once they had actually made it to Paris. As it was - well it was just a matter of a thought, to travel and Aziraphale had that very thought, the exact point where he wanted to arrive was held in his mind and of course with Crowley beside him.
Only.
Nothing happened. They were not whisked from this place and to their correct destination. They had not moved at all. And Aziraphale the self proclaimed level headed being that he was, could not find it in himself to admit just yet that they might just be stuck here. And so rather than mention his attempt at traveling second time instead what he said was. "Crowley, would you be a dear and get us to Paris, and we'll simply put this whole scene behind us."
