Remember, Incite emotion is a mental stress attack. Courage isn't really a mental stress attack type of emotion... If you want to go for something along those lines, design a presence-based (or possibly conviction-based) stunt to get the whole "inspiring courage" thing going. That's not to say there aren't situations where courage can get you killed, but mental stress, not so much.
I really, really, really would recommend you NOT letting your WCV take courage as incite emotion. For me, that's the same category as Hope, Love, etc, if perhaps a milder version- which is part of why I'd put it as a mortal stunt. Remember, White Court Vampires are STILL Vampires. It should be HARD to be heroic as a WCV. It isn't much of an inner struggle against your monster when sunshine and puppies keep you well fed. If you want a fun RP experience for a struggling-against-my-inner-monster WCV, I'd go with despair or anger- Lust, which Thomas struggles with considerably, is in my opinion the easier side of things from a non-monstrosity point of view.
