We've got to see Dany(and Jon) sitting on the Iron Throne at some point, and it can't just be that in the show finale Jon kills the Night King, pops of to the coronation and then we get end credits. That would suck considering that the show has been building up to a new kind of rule for Westeros, so we have to
see them rule, fight the army of the dead, make some tough decision, maybe even face some opposition, and there's only 6 episodes left.
Heck, we had Robert as king for 7 episodes and he was just a plot device
