Emma was wondering that too. She was tempted to ask the obvious question, the incriminating question: whether Izzy still was interested in her, even after their talk in the supermarket carpark, and if Izzy was, what she planned to do about it, exactly.
Emma was tempted to ask, but she knew she wasn’t going to. Mostly because she knew what a terrible, unfair idea actually asking that would be. It wasn’t fair to encourage Izzy, and asking something like that would be encouraging her. It wasn’t fair to let Izzy think they were still flirting, and that there was a possibility of something happening between them, when Emma knew nothing was going to happen. Or at least, she hoped nothing was going to happen. Her uncertainty didn’t change the unfairness of it, though. It was still unfair, either way.
