Vriska is definitely quantifiable enough. Noir is also very quantifiable - there's already a character nommed that set the bar for what I'd allow and Jack is nowhere near his level.
EDIT: Also, for some reason AIM is a total failure and isn't letting me enter the Controlmemo group, so I've made a new group for any questions you guys might have. It's sburbmemo, no caps. Sorry for the inconvenience!
