QUIZ: Can you name who killed these characters on Game of Thrones?

Anything less than 90% and we're sending you to the Wall.

Valar Morghulis. To quote Cersei, when you play the game of thrones, you win or you die. With this in mind, can you name the characters that killed these 20 people in the TV show. Obviously, spoiler alert. To further clarify things, we're looking for the person - or entity/creature - that delivered the fatal and final blow. In one circumstance, we'll accept any option from an equally guilty pairing (wink, wink) Go!
