Well now that you put it that way, I feel like I need to go back and do some editing.  You see I didn't think of it like you put it.  What I was thinking was Ev could sense Free's aura because it was familiar to her, but really all Evelyn can sense is spirits of the dead. Come to think of it, I was kinda out of it when I posted, so yeah none of it really makes sense.  Sorry for the fuck-up XD. I'll fix it.

EDIT: Situation handled ^.^  Still kinda put it to where at least Evelyn noticed her.
