Well, that hadn't been what Crowley was expecting. Though he wasn't sure what he had been expecting, but whatever it was, it wasn't that. So she was a demon, that was... good? He supposed it was good because it meant his original decision about her was correct.
She was definitely from a different world, though. “In your world, demons are raised?” He asked curiously. That was an odd notion. Crowley was okay a being a demon, but he wasn't the best of it either. Perhaps if he had been raised a demon as opposed to falling from Upstairs, he would be better at it. Even so, he still considered himself pretty alright at what he did do.
He shrugged and indicated the seat on the bench beside her. The required investigation. “In our world, we fall... from Upstairs.” He couldn't bring himself to say Heaven or Angels in the sentence. Both reminded him of Aziraphale and wondering when and if the Angel would get to the City. “Never heard of a demon being raised by humans. Antichrist, sure, but he wasn't a demon.” So to speak.
