Lily was still kinda inexperienced with her augmented sense of smell. As important as it was to the use of her powers, in some ways it was still a bit of a black box to her. She could smell a person's biology, and their emotions - which at the end of the day was just smelling the subtle biological changes that they perceived as their feelings - but the truth was that as skilled a biologist as Lily was, she didn't actually have a clear mental map of specific scents to particular biological markers. She knew what biochemical markers would come up to, say, test a person's blood type. And she could smell those biochemical markers. And so she could smell a person's blood type.

But she herself had never actually, personally learned what say Type O blood smelled like, at least not before she had first smelled it with her powers, at which point she had known it was Type O. She hadn't recognized it as a matter of prior familiarity, her brain simply categorized that particular smell as Type O blood, instinctively and automatically.

Right now her sense of smell wasn't giving her much to work with at a conscious level. She wasn't consciously noticing anything of particular value, that they weren't already aware of.

But the senses did a lot of their work unconsciously. Took in a lot of information that was never actually promoted to conscious awareness. And Lily's sense of smell did even more of that. Somewhere in her head, her brain was taking the scents she picked up and matching them to concepts she understood, even if she didn't know what the concept itself should smell like.

So here, now, even though Lily wasn't consciously aware of any specific scents, even if she couldn't have consciously mapped them onto a known concept if she had been, her brain processed the scents that came in through her nose and told her exactly what this camp smelled like.

It. Smelled. Fake.

Lily fixed Sandy with an unimpressed stare and crossed her arms before her. "Or you can stop wasting our time with illusory tricks and reveal yourself," she said simply. There wasn't a hint of doubt in her tone, not even allowing for the possibility that the woman before them might have been real.
