"I didn't realize the grounds were off-limits to everyone else. Terribly sorry," Aziraphale said icily, his momentarily stunned look gone. "Anyway, I was looking for you. I wanted to invite you to supper. I went to the rooms and Chicago looked a little lonely." His face softened. "I took her along. I wasn't expecting to have to look outside. Do you have any idea what time it is?"

He glanced at Ellie*, face apologetic. "I am sorry I interrupted you both. I see Crowley has spoken to you about her. Isn't she absolutely adorable?"

*He didn't look quite at her. It wasn't that he was uncomfortable with her nakedness, or that he had never seen a woman's naked body before**. And it certainly was not because she was unattractive! It was only that Aziraphale was simply and wholly uncomfortable with "girl bits". Crowley was clearly far more comfortable than he was.
**He hadn't seen one recently.
