Appreciate you holding the contest for us GOT enthusiasts. It was fun seeing the different predictions. As like you, I was surprised the Night King met his death in one show. The episode was gripping for sure but he was killed off so..one show easily. I will be expecting a prolonged battle and death in the book, whenever that will be released.
The two dragon lives, woohoo! Both you and josediccus predicted one death. We need both Dany and Jon to ride them into battle (in sunlight where we can see). 😉
