[@Themerlinhawk][@Caits] Kewl! Paulina's always down for researching people's abilities, so, we could say that in conjunction with the Academy's researchers they figured out a fairly good idea of how Ashleigh is able to sense people's emotions at all, and then Paulina wrote an enchantment that acts like a set of mental earplugs, suppressing her senses enough that she could easily ignore others emotions even in a large crowd. Since the enchantment has to be written on something, it could be attached to an accessory that she wears, or as a tattoo that she has somewhere on her body.
