Game of Thrones has many fine characters, but they all persuade enemies and allies throughout the Seven Kingdoms in very different ways. Most of those ways involve backstabbing or slaying other houses, proving their strength over other characters.

There's also analysis of various scenes - particularly with Dany and Tyrion - showing how characters use different methods of persuasion.
If you've seen all of season six, it's a great look back at the series and some of its most popular figures.
If you like cinema being broke down in this way, there's also a video that breaks down the sales training scene from Boiler Room.
