Who did you make a rationalist? Also, linky?
I haven't submitted it anywhere yet. I've asked some friends to read it first. That way if I'm one of those horrible fanfic writers who can't understand how bad they are, I can spare myself the humiliation.
Also: Nunnally is the rationalist. Lelouch is a bit more methodical as well.
I've been enjoying reading Less Wrong fanfiction, and I wanted to suggest another fandom that should have at least one rationalist fanfiction: Mage: The Awakening. It's a roleplaying game about "modern sorcery." My description can't really do it justice...
