Oh my god, that fic is so OLD! I'm glad you liked it. (I always meant to write more Vayne, but it never quite worked out. Somewhere on my hard drive is a never-finished WIP entitled 'Notes Toward A History of Ivalice' which was meant to be the Vayne Is A Terrible Colonialist Emperor fic...)

And yeah, I get snapshot personalities off of perfume! It's part of why I love it, I get to be Other People while I wear certain scents.
