Chiquito loving burritos is no surprise to me. Mostly because I read his name as that brand of mini tacos they sell in the refrigerated section. *snerk* Maybe you could give your OC's reasons to keep their mouths shut? Hmm. Or maybe introduce the new characters via scentnames that are really distinctive. Like... birthdaycakeicing or dragsitchybutt or strongblacktea or eatsownvomit XXD

Have you thought about keeping a set of standard OC's to reuse in different fics? Not for O-fic, but fanfic. It'd give you memorable background characters without having to recreate from scratch every new fic... Er, just an idea. *shuffles feet*
