Game of Thrones:

Who has an explanation for why the army of the dead has been woven for so long?

YYY: The King of the Night just doesn’t need it all, he likes to sit on a horse and look at the army of the dead from somewhere above.

zzz: The King of the Night is like Moses, he loves to drive the crowd here and there, in 40 years, we will go out to the Promised Land.
