I think Machiavellian would be a good adjective for it (it apparently is also one of the dark triad personalities).For the skill, I put tracking, as Joras was taken on numerous hunts for his father, although I"m sure he'd have preferred to hunt a different prey.

Tracking is covered under survival. It would work as a knack. Also I just noticed you put 'educated' as a skill. That is to broad. 

I'm going to add some more skills to the list to help you and future player out a bit with this aspect of character creation.
