It’s very hard to convince people that the mission beyond the Wall+the grand parley next week from the show won’t happen in the book. Do you think it’s likely these may happen in the books?

A mission beyond the Wall? Yes. Jon and co are bound for the Heart of Winter, so I see that happening.

This mission? No. The books already established that wights who go south of the Wall stop being reanimated and rot away. The show dropped that little plotline, but it’s there in the books.
