Why haven't the defenders of Winterfell, in S8 of GOT, at least contemplated using wildfire to defend the castle (and humanity)?
I just watched 8.2. The defenders of Winterfell have been armed with Dragonglass and Valyrian steel as much as possible. But no-one has brought up wildfire. Why?
We know regular fire is effective against the walking dead. We know wildfire is pretty useful when defending a keep. Tyrion has used it, Sers Davos and Clegane have seen it being used, Cersei has used it. So why don't they at least fill some of the frozen trenches with it, instead of pointed sticks?
