Jaime will kill Cersei, Sansa will be pissed at Jon (AA reborn), Jon will have to kill somebody (Arga or Ghost?), Euron has a horn that's a dragon binder (supposedly), and will Bran lead the WW through the wall? Lannisters are screwed, they have nobody. Need to resolve the human battle quickly, then delve into humans vs WW.
If Jon kills anyone it's Sansa.
